  • Mostrar Abstract
  • The problem regarding anthropic actions and, consequently, the impacts of the silting up processes in the Rio Branco hydrographic basin refers to the changes, in the short and long term, that bring losses to the river flow of the area under analysis. Chapter 1 of this research seeks to relate the importance of education for water resources in conjunction with social function and action, in order to consider that the implementation of new methodologies must consider the local social reality. Still, one must consider the relationship between environmental problems such as silting up and water scarcity with the need to repair, mitigate and prevent anthropogenic actions. Thus, the use of low-cost alternative technological instruments makes it possible to popularize research in different spaces, causing transits and contacts with different places and subjects, since alternative and low-cost technologies can be transformed into pedagogical and educational instruments capable of shaping an environmental and social reality. Chapter 2 addresses the importance of society's participation in mitigating the water crisis and aims to discuss the importance of social participation in mitigating the water crisis, through environmental education and citizen science, combined with alternative cost technologies reduced and accessible, which can be used both by students in the classroom and by the population for the promotion of citizen science and environmental education, in the mitigation of local environmental problems.

  • Mostrar Abstract
  • Technical Assistance and Rural Extension (ATER) is defined as a public policy that aims to bring technical assistance to rural properties, improve work processes and, consequently, the quality of life of farmers. The ATER service, through its agents, is the inducer for the development of rural communities in Brazil and in the world. The biggest environmental impacts emerged within the Brazilian agricultural reality in the middle of the last century. The lack of planning for an adequate use of water and the poor infrastructure caused socio-environmental problems. Access to water is a primary factor, without which nothing is done and nothing is produced. The main public policies, initiatives and techniques related to ATER and conservation of water resources in the Jauru river basin in Mato Grosso, developed by ATER entities, were surveyed, and the results from the point of view of the extensionists involved in the projects were described, of the effects for the qualitative and/or quantitative improvement of water resources. Among socio-environmental impact programs and projects that were executed in the basin are PRONATER (National Program of Technical Assistance and Rural Extension in Family Agriculture and Agrarian Reform), POLONOROESTE (Integrated Development Program of Northwest Brazil) PROVÁRZEAS (National Program for the Use of Irrigable Floodplains) and the new Brazilian Forest Code (Law 12.651 of May 25, 2012).

  • Mostrar Abstract
  • Wetlands have relevant functions, which affect not only ecological relationships, but also the current
    civilization model and the development of human agglomerations in their physical space. In the
    occupation of space in these regions agronomic management practices are used, among which is
    drainage, whose application is necessary for the water table and accelerate surface runoff. This
    engineering work is a mandatory environmental licensing activity, under the terms of CONAMA
    Resolution nº 237/97, however, this environmental management instrument does not have its
    procedural rite defined by the environmental agencies. Therefore, we justify this research with the
    elaboration of guiding elements to the regulation of CONAMA Resolution nº 237/97 and the decision
    making regarding the use of these activities in wetlands in Mato Grosso state, for the sustainable use
    of water resources. The objective of this work is to elaborate a proposal for a Normative Instruction
    on environmental licensing in agricultural drainage channels in the State of Mato Grosso. For this,
    research was carried out based on a systemic review of existing literature, relevant to the technical
    nature of the construction of drainage channels, to the hydrological changes produced by their
    installation in Wetlands and to the legal conjecture of their environmental licensing. The research
    took place from the analysis of scientific productions registered in the electronic research addresses,
    carried out through the following search engines: Scielo, Capes and Google academic, from July
    (2020) to April (2022). From the analysis of the bibliographic material, the existence of productions
    relevant to the theme was obtained. From these data, we found the occurrence of environmental
    damage and mitigating measures, the historical analysis of the use and the legal support of this on
    wetlands, including their current situation at the global, national and local level. The results also
    revealed Governments' relationships with drainage channels and wetlands, and with these, their
    challenges. The conclusion of this work led to the preparation of a proposal for a Normative
    Instruction concerning the licensing of drainage channels for agricultural practice in humid areas in
    the State of Mato Grosso.

  • GRANT AS AN INSTRUMENT FOR MANAGEMENT OF
    WATER RESOURCES IN THE STATE OF MATO GROSSO

  • Mostrar Abstract
  • Water, as a natural resource, is an element of fundamental importance for life, both for the maintenance of ecosystems, for meeting basic human and animal needs, and as an input in most processes of human productive activities, contributing to the social, economic and cultural development of the world. However, water is not available in a balanced way on the planet, presenting great spatial and temporal variability. These facts, associated with the growing consumption of water to satisfy its multiple uses, have made the water availability in certain regions of our planet insufficient to meet all the demands and to maintain the minimum environmental conditions necessary for sustainable development, generating , in some places, a situation of water scarcity, causing negative environmental impacts and contributing to the occurrence of conflicts between users. In Brazil, according to the legal framework, water is considered a public domain good and its right to use is granted through the issuance of the so-called granting of the right to use water resources, which was established by Law No. In the state of Mato Grosso, the granting of the right to use water is governed by Law 6,945 of 1997, which establishes the State Policy on Water Resources, the granting being one of its instruments for managing and regulating water resources. This management instrument has the characteristic of being a command and control tool, and its objective is to ensure the use of water, with quantitative and qualitative criteria, in order to guarantee the effective exercise of the right of access to water resources by the user, in addition to to seek to protect water resources, through criteria and conditions that must be respected. Although the grant has several positive points, in Mato Grosso, it lacks improvement and, currently, it runs the risk of having its application finalized with the issuance of the granting act, which would invalidate its purpose, considering that it is not limited to to the simple issuance of the act of granting. That said, this work, in addition to analyzing the grant system carried out in the State of Mato Grosso, wants to point out solutions aimed at promoting greater efficiency to the grant instrument. The development of this work took place by means of a survey of information carried out with the water resources management agency (SEMA/MT) in its database, plus an extensive bibliographic and documentary research regarding the management of water resources. Finally, a grant manual was prepared with a view to facilitating water user access to technical and administrative granting procedures. The analysis of the data of this work showed that there are certain deficiencies that, if overcome, could give greater effectiveness to the instrument of granting the right to use water resources for the attainment of the purposes for which it is intended.

  • INFILTRATION WELL FILTERING SYSTEM ADAPTED TO URBAN WAY DRAINAGE - HEAVY METAL MITIGATION

  • Orientador : FRANCISCO LLEDO DOS SANTOS
  • Data: 25/10/2021


  • Mostrar Abstract
  • In cities, flooding negatively impacts the lives of its residents and passersby, who are unable to move during heavy rains, with potential human losses, in addition to material goods, coexisting with the risk of contamination through direct or indirect contact with the water retained in the track. With the premise of addressing this issue, this research brings, as a structural alternative, the use of an infiltration well adapted to mitigate flooding, adjunct in parallel to the public rainwater drainage system. It is capable of promoting the return of water resources to the water table through infiltration and, notably, free of external pollutants. Thus, a filtering composed of layers of sand and granular activated carbon was proposed in this structure, together with a non-woven synthetic blanket separating the soil from the other materials, in addition to a pre-filter as a complementary structure to remove a greater fraction of solids. presents in the urban environment, which reduce the efficiency of the process. The system was given the name of Improved Infiltration Well, having as criteria in the choice of its components its retention sources, durability, filtration time and cost/benefit. In the mathematical modeling, the pre-filter proposed retention of 2.26 to 80.52% of the sediments in the dynamic flow condition, especially for a range of 0.063 to 2mm, while in the medium sand filter a greater retention is predicted in the range 0 .1 and 0.2mm, with removal of 12.38% of the sediments. Granular activated carbon was used in the retention of heavy metals, such as Lead (Pb), Chromium (Cr), Cadmium (Cd) and Nickel (Ni), and the filter efficiency was evaluated through a comparison with the results received in runoff water, corresponding to the rainy season for a delimited urban environment in the city of Cuiabá-MT. It was possible to overcome that each gram of filtering material has a capacity to retain contaminants such as Pb and Cd, respectively of 12.05 mg and 30.58 mg, above those observed in the field, so that such material is in a condition for removal of even more metallic compounds, conferring greater health to human and the environment, while the elements Cr and Ni were not necessarily found, offering no risk as underground safety water or having the need for a filtration process. Subsequently, the geometry and other technical specifications sufficient for a satisfactory filtration are defined, allowing the amount of contaminants present to meet the determined concentration limits, determined in current legislation, namely: CONAMA resolution No. 396 of April 7, 2008, among others.

  • SPACE-TEMPORAL DETECTION OF CLIMATE EXTREMS AND ITS INFLUENCE ON FIRES AND WATER RESOURCES USING REMOTE SENSORS

  • Orientador : CARLOS ANTONIO DA SILVA JUNIOR
  • Data: 29/10/2021


  • Mostrar Abstract
  • The imbalance in the supply and demand for water caused by natural events such as drought is capable of destabilizing human activities. It is estimated that by 2030, approximately 700 million people will be impacted by the effects of drought, which have a significant impingement on social and economic spheres. Changes in climatic patterns indicate that dry periods will be intensified, and as a result, episodes of forest fires and an amplification in greenhouse gases (GHG) emissions will increase the risks to global public health. Between 1999 and 2018, there were heat sources in all Brazilian biomes. These emissions from the burning of plant biomass, contribute to the country being one of the world's largest emitters of greenhouse gases. In Tocantins, drought events that occur mainly in the southeastern region of the state, as well as the high number of heat sources, represent a direct risk to communities, the environment and water resources. In this work, the study area comprises the Manoel Alves da Natividade River Basin - BHMAN, due to its important role to agriculture and to the communities inserted in this study area, which depend on this water resource. Through the use of remote sensing techniques, drought events (using the standardized precipitation index - SPI), and heat sources (through products available by the MODIS sensor) will be analyzed, in order to identify the possible synergistic pattern established by both factors, to then elaborate a methodology that helps the monitoring in hydrographic basins.

  • Mostrar Abstract
  • Water, health and food insecurity can happen even in countries with plenty of resources, such as Brazil. Due to its continental dimension and the non-homogeneous distribution of income and resources, this discrepancy between regions is caused, an example of this is access to water, Brazil, while concentrating a generous portion of all fresh water available in the world, has some of its inhabitants with considerable difficulty in accessing water, and this access is measured not only in quantity but also in quality. This type of difficulty can occur in the outskirts of cities, however, higher rates of water shortages occur in small rural properties, especially those with production characteristics for subsistence. In addition to water supply, these people in rural regions may suffer from the lack of other basic sanitation services, such as the correct disposal of effluents, which ends up serving as a vector of diseases, which affect mainly children, increasing even the rate of child mortality. Combined with these two problems, the lack of nutritious and sufficient food further reduces the quality of life of the population that is already vulnerable. All these factors make rural populations have only subsistence production characteristics, not being able to produce beyond their own consumption and consequently not improving their living conditions. Therefore, Social technologies for small rural properties brings some technologies, which are based on millenary knowledge, to try to help small producers to gain access to these services, guaranteeing their water, sanitary and food security. Technologies were chosen that have the characteristic of reasonably easy deployment and low cost, this is because they are low-scale implementation technologies, and should only be used for single-family homes. The manual's main approach is to help the small producer choose, install and maintain the technology on their own, with little or no need to hire third parties.

  • Data: 26/11/2021


  • Mostrar Abstract
  • Water resources are one of the main factors for the maintenance of life on earth, in addition to being a means of carrying out numerous social and economic activities, due to this great importance there is also a great concern on the part of society about the pollution of water resources arising from production agricultural scale, especially in commodities. The use of pesticides is closely linked to the pace of production, that is, the more areas that are suitable for agriculture, the greater the use of these agricultural inputs, which in turn can cause major impacts on water resources and their ecosystems and on the soil microbiota. Given this environmental concern, this work is justified by the acquisition of information and identification of the active ingredients present in agrochemicals used in the main crops in the municipalities in the drainage area of the Alto Juruena hydrographic basin, in order to understand the risks that these substances represent in the process of pollution of the surface water by pesticide, through the survey of quantitative and qualitative data, especially from government agencies and regulatory agencies, data tabulation and application of a specific algorithm that indicates the risk of contamination of ground and surface water in the study area by the solubility of the pesticide in water, for its half-life in the soil and its infiltration power in the soil. It was observed that in the region there is a high rate of use of pesticides with high power of environmental contamination as well as toxic to human health, such as the herbicide Paraquate, which was banned for sale in Brazil in 2020.

  • Data: 29/11/2021


  • Mostrar Abstract
  • The implementation of the National Water Resources Policy in the scope of the Hydrographic Basin is still a challenge for the management bodies. Therefore, the Hydrographic Basin Committee, a collegiate body, part of the Water Resources Management System that brings together representatives of public authorities (Municipal, State and Federal), civil society and users of water resources, is relevant in the consolidation of a hydrographic basin as a unit territorial planning and management. From this perspective, we assume that, in addition to the attributions conferred by Law 9,433/97, which is the responsibility of the Hydrographic Basin Committees, the function of managing the use of water resources in an integrated manner with the participation of government entities and civil society in conservation of the natural environment and environmental impacts, arbitrate the conflicts caused by the use of water resources in the basin. In the case of the Jauru River Hydrographic Basin, the main river in the Pantanal, it has intensified in recent years, with advances in the energy sector for the implementation of an energy undertaking of Small Hydroelectric Plants (PCHs). The objective was to analyze the process of water management in the Jauru River hydrographic basin by the hydrographic basin committee and the conflicts generated from the implementation of the Small Hydroelectric Power Plants (PCHs) energy undertaking. The research object is qualitative, descriptive, exploratory, and for this purpose, the form sent electronically to members of the CBH rio Jauru was used, prior contact was made explaining and clarifying the objective of the work and the importance of this study. This work aims to analyze the management of water in the hydrographic basin of the Jauru River/MT: Role of the Jauru River Hydrographic Basin Committee in the implementation of Small Hydroelectric Plants (PCHs). By analyzing the perception of committee members about the implementation of energy projects through Small Hydroelectric Plants (PCHs) in the hydrographic basin, it points out a failure in the management of the water resource, as a result, affects the exercise of governability and governance of the Jauru River hydrographic basin committee itself . As a final proposal for this research, there is a Draft Socio-environmental Agreement Product to be used as a subsidy instrument for the CBH of Rio Jauru and participants who make use of the water resource in the hydrographic basin.

  • Mostrar Abstract
  • There are gaps in systematic knowledge of the situation of groundwater in Brazil that make it difficult to identify and delimit the extent of the problems that affect aquifers and their users. Among these, one refers to the lack of mechanisms in the States to systematize, store and mainly disseminate data relating to groundwater, which hinders the organization and production of information in the definition of strategies for implementing the technical and legal instruments of their respective policies of water resources. This research aims to develop a digital and online mapping system that can be used as a support tool for management by public agencies, through access to a set of technical information on the underground well submitted for environmental licensing in the State of Mato Grosso. For the preparation, data from registered, authorized and authorized wells in the State, provided by the Superintendence of Water Resources of the Mato Grosso State Secretariat for the Environment were used. Data were standardized and entered into a public interface of spatialized data in the form of interactive maps, accessible via internet browser, built with free and open source tools and services (Leaflet and GitHub) that allow for use and collaboration by the community. A web platform was then resulted with a dynamic map containing information on hydrographic basins, road systems and existing aquifer systems in the State of Mato Grosso and the location of granted wells demonstrating the use of groundwater, with free access for use by the government agencies and users. It is expected that through the online and public publication of data from underground wells granted by SEMA-MT, until then with restricted access, it can serve as an information tool for the general public and assist in the management of water resources for public and private agencies, organizations and other interested parties, in addition to providing a collaborative repository that allows the use and updating of groundwater grant data.

  • Mostrar Abstract
  • As anthropic actions in hydrographic basins are intensified, the availability of drinking water to people is proportionally reduced. Multilateral organizations such as the UN have provoked countries to promote the 17 sustainable development goals of the 2030 agenda; and the sixth deals with “Ensuring the availability and sustainable management of water and sanitation for all.” Brazil has about 12% of the fresh water available on the planet, but it is disproportionately distributed among its regions and among its population. The State of Mato Grosso, a reference in agricultural production in the Cerrado, has its territory inserted in three hydrographic regions: Amazon, Paraguay and Tocantins-Araguaia. The State's water potential expands the participation of agribusiness in new agricultural investments (irrigation/aquaculture). The Manso hydroelectric plant was the first with a reservoir to be installed in the state, which, in addition to producing electricity and controlling the flow of the Cuiabá river, caused irreversible damage to the environment and conflicts between the APM – Manso and the families who were relocated from the area flooded by the reservoir. Part of these families were relocated to the resettlement projects created by Furnas. Two decades after the formation of the reservoir, this study sought to understand the contribution of the Manso reservoir in improving the quality of resettled people through socioeconomic development. Therefore, its general objective was to characterize the effect of the APM-Manso Reservoir on the socioeconomic development of the Bom Jardim, Campestre, Mamede and Quilombo Resettlement Projects. The research area was constituted by the Resettlement Projects in question. The method used was the case study and data acquisition was carried out in two phases: the first documental and bibliographic research; and the second field survey. The data collection instrument was the checklist, consisting of the items: a) infrastructure; b) agricultural activities; c) environment and sustainability; d) batch technification; f) water and soil and g) other relevant observations; the checking of the checklist items was carried out in each batch participating in the research. Regarding the Campo research, seven lots in the Bom Jardim resettlement, eight lots in Campestre, eight lots in Mamede and eight lots in Quilombo took part in the research. The sampling considered only the lots that had families that were resettled by Furnas. For a better presentation of the results and discussions, in the Study, they are presented in the form of chapters. In chapter I, themes related to water are presented, which seeks to understand its dynamics of availability among Brazilian regions, as well as realities present in the installation of hydroelectric plants, such as the creation of resettlement projects. In chapter II, a diagnosis of the hydrographic basin of the Manso River - BHRM is presented, with emphasis on the morphometric, pluviometric and pedological characteristics of the basin. Also, data on the population and economic activities developed in the municipalities that make up the basin are presented. Chapter III presents facts that are associated with the implementation of APM Manso and its consequences for families settled in the resettlement projects created by Furnas. In chapter IV, the results of the analysis of data collected in the field are presented with a checklist, which demonstrates soil fertility, water and economic limitations, which limit the development of agricultural activities, even with the abundant availability of water in the reservoir. In the Study, the conclusions lead to consider that two decades after the inauguration of the APM Manso, the Manso reservoir did not effectively contribute to the socioeconomic development of the Bom Jardim, Campestre, Mamede and Quilombo resettlement projects.

  • Mostrar Abstract
  • The water governance model in Brazil is integrated by political, economic and social guidelines which, as a consequence, has its use affected at different social levels. Thus, it is determined, to whom the water is directed, its time of use and form of abstraction, and also which type is appropriate, also determining its right to use, its services and its benefits. In this management process, the participation of different sectors is of paramount importance, ensuring the availability of water in adequate quantity and quality for multiple uses. In view of this situation, the National Water Resources Policy, Law No. 9,433, instituted on January 8, 1997 - characterized by establishing the instruments for the management of water resources in the federal domain, enforced the aforementioned guidelines, thus creating the Hydrographic Basin Committees, conferred on them the management of water resources in an integrated manner and with the participation of society. The present work aims to evaluate the governance methodology implemented by the three River Basin Committees of the Teles Pires River, for the implementation of Water Resources Management Instruments, and through the application of tools that can support the water governance strategy with a focus in common issues between the committees but which are treated with individual planning, suggest the integration of their actions aiming at a better adjustment and efficiency of them. The methodological procedure used in the research was qualitative, exploratory and participatory. A document search was carried out on the ANA and SEMA-MT websites, an analysis of the documents and minutes produced by the committees, and a questionnaire was given to the members, in order to analyze their degree of perception of the current reality of the committees and the commitment of each one . According to the results obtained, the basin committees still have little maturity in the process of implementing the water resources management instruments, the interviewees have little time available for questions related to the CBH, the support offered by the government agency is below the demands of the committees, which impacts on not reaching minimum indicators of the governance process. Thus, as a product of this dissertation, a matrix was developed which contains the positive and negative factors of the current situation of the Teles Pires Basin Committees, characterizing the search for a management improvement process with more efficient decision-making, achieved through actions associations between the committees of the Teles Pires Basin.

  • PRELIMINARY TECHNICAL STUDY ON THE CLASSIFICATION OF DYES AS AQUATIC ENVIRONMENTAL CONTAMINANTS IN  MATO GROSSO STATE

  • Orientador : ADLEY BERGSON GONCALVES DE ABREU
  • Data: 08/12/2021


  • Mostrar Abstract
  • The availability of fresh water in the world is compromised due to several factors, among them, the concern is greater due to irregular dumping or, without treatment of industrial effluents directly in the water bodies, generating a huge damage to the environment. Effluents containing dyes are the most worrying, as they contain a high load of organic chemical compounds, do not degrade easily and are highly toxic to the environment. Thus, the objective of this work was to carry out a bibliographic survey of information related to the toxicities of dyes in the aquatic environment, identifying the toxicity levels of the dyes listed, the result of toxicity found should be forwarded to the State Secretariat for the Environment (SEMA) in order to subsidize the lowering of a specific technical standard classifying the dyes in the category of environmental contaminants to meet the requirement of State Law No. 10,748 of August 2018 of the State of Mato Grosso. The methodology applied was exploratory and explanatory research, which was guided by the bibliographic survey of the information in the documents: technical standards, legislation, scientific articles, theses, published dissertation that deals with the area in question and that used tests with test organisms. After studying and analyzing vast material, it was possible to observe that among the identified dyes, azo dyes have higher levels of toxicities than other groups, especially the acute level, in addition to presenting carcinogenic and mutagenic activity, cytoxicity, clastogenic and cytostaticity / genotoxicity potential. So we can conclude that, in the case of dyes, more water-soluble compounds tend to induce less toxicity, whereas less soluble compounds tend to be more absorbed by organisms and, consequently, are more likely to induce toxicity. It should be noted that for the detection of dyes in the environment, it is necessary for the environmental agencies to establish a monitoring program that uses analytical technological tools for a more accurate analysis of the occurrence of dyes in water resources within the state of Mato Grosso, so that this, can quantify the levels of concentrations of the order of microgram per liter (µg / l) or lower, thus enabling the process of environmental risk assessment.

  • Data: 16/12/2021


  • Mostrar Abstract
  • The current scenarios of real estate projects are growing in large urban centers mainly due to state policies for financing real estate. By concentrating a large part of the public and private sectors, the capitals end up standing out in this context, reaching extraordinary numbers in real estate expansion. The positive aspects of this sector's heating are the increase in indicators such as the Gross Domestic Product (GDP) and the Human Development Index (HDI), generation of jobs in civil construction. On the other hand, points that require great attention must be observed, such as the zoning of the city and public policies to minimize environmental impacts, ensuring the supply of quality water and sewage treatment as a priority for human survival. Naturally, such critical points will be addressed if the municipal government is in line with national policies. The standard procedures for receiving, analyzing and approving sanitary sewage projects filed in the municipality of Cuiabá are based on Decree No. 6714 of September 3, 2018, establishing for those interested in obtaining construction permits, occupancy permits, urban projects and licenses and environmental adequacy and other measures. Thus, considering the relevance of Decree No. 6714/2018 in the aspect of quality of life, a survey is proposed to investigate the impact of this legislation on urban expansion. This work intends to map the real estate projects carried out around the Coxipó River in the period from 2018 to 2021; identify those projects approved based on Decree No. 6714/2018; observe whether the processes for discharging effluents into the Coxipó River are complied with and assess the quality of water in these locations. Finally, a technical document will be prepared presenting in detail the strengths and weaknesses of Decree No. 6714/2018. It is expected that the reflections and propositions encourage discussions and help in decision-making by entities that exercise the power to improve this body of water.

  • Mostrar Abstract
  • The Guarani Aquifer System (SAG) is one of the largest freshwater reservoirs in the world, and
    has been widely explored due to the quantity and quality of stored water, mainly in the outcrop and
    recharge areas where the aquifer is free (not confined). The outcrop and recharge areas are considered
    to be highly vulnerable and changes in land use and the activities carried out can impact the recharge
    potential and cause changes in water quality. The State of São Paulo is located under one of the outcrop
    and recharge areas and due to the high population density in the area covered, it is subject to constant
    transformations due to urban, industrial and agricultural expansion. The spectral-temporal analyzes of
    anthropic interference in water production were carried out in four delimited areas, located in the
    municipalities of Boa Esperança do Sul, Bofete, Brotas and São Simão, in the period from 2012 to 2018.
    The rain index was obtained through of the CHIRPS system. The actual evapotranspiration rate was
    obtained using the MODIS Sensor. The information on lithology and piezometric level was obtained
    through RIMAS of the Geological Service of Brazil. Hypsometric maps were made from images from the
    ALOS / Sensor Palsar satellite. The recharge estimates were performed using the computer program
    ESPERE, using the WTF (Water Table Fluctuation) method. The variables of land use (forest, exposed soil,
    anthropic use and water courses) were obtained through the Normalized Index for Fraction Difference
    proposed by Souza et al. (2005) supported by the Linear Spectral Mixing Model (MLME) algorithm
    through images from the Landsat 8 Satellite / OLI Sensor. Boxplot statistical analysis, canonical variables
    and Pearson's correlation, were performed using software R. The study areas showed significant
    anthropization. The study area located in the municipality of Boa Esperança do Sul presented a
    significant area with exposed soil, one of the smallest forest areas, one of the lowest evapotranspirative
    rates, and the lowest recharge potential. The study area located in the municipality of Bofete, presented
    the smallest area of exposed soil, one of the largest forest areas, high evapotranspirative rate and the
    greatest recharge potential. The study area located in the municipality of Brotas had one of the smallest
    forest areas, the lowest evapotranspirative rate and one of the lowest recharge potentials. The
    municipality of São Simão, despite having a forest area with a median higher than the municipality of
    Bofete, had a significantly lower evapotranspiration rate, and had the second highest recharge potential.
    This work is presented as a methodological suggestion for researchers and professionals in the area of
    water resources who are interested in carrying out similar studies in other areas of outcrop of the SAG.
    The study aims to contribute as technical support for the decision making of the National Water
    Resources Management System (SINGREH) and with the provisions of State Law No. 9866/1997, in order
    to contribute to the sustainability of the Guarani Aquifer System.

  • Mostrar Abstract
  • Irrigation is a technology that allows greater agricultural productivity, as it maintains production stability, regardless of climatic fluctuations. However, it is the largest water consuming activity in Brazil. With a slightly rugged relief, good supply of water and because it is located close to the BR 163 and BR 364 highways, the main grain transportation routes to Brazilian ports, the Alto Teles Pires basin region stands out in the national agribusiness scenario, being recognized for its high productivity and irrigated and mechanized production. The rapid and growing expansion of irrigated agriculture in the region may impact the demand for the use of water resources. This paper aims to demonstrate, through remote sensing techniques, the growth of center-pivot irrigation in the Alto Teles Pires basin over a period of 24 years, analyzing the trends of expansion in the coming years and areas of the basin with the greatest potential to expand irrigated agriculture. The results indicate an expansion of 396 times the number of pivots in the studied period, with the total area irrigated by a center pivot in the last 5 years growing by 44%. As for the areas with potential for expansion, they correspond to about 42% of the total area of the basin. The data obtained is key to management and public policy actions in the region, since the expansion of uncontrolled irrigated agriculture can generate conflicts of water use and compromise the availability of water in the basin. Therefore, identifying and monitoring the expansion of irrigated areas is essential for water management in river basins and for the effective implementation of the instruments of the National Water Resources Policy, such as the granting of use and the monitoring of rivers.

  • Mostrar Abstract
  • The  use  of  economic  instruments  applied  to  the  management  of  water  resources corroborates  the  recognition  of  water  as  a  good  endowed  with  economic  value,  as recommended  by  the  National  and  State  Water  Resources  Policies,  Laws  9.433/97 and 11.088/2020, respectively. The charging, carried out in some basins in Brazil, is not yet implemented in Mato Grosso, however, the subject is the target of discussions that  goes  beyond  the  scope  of  the  State System  of Water  Resources  regarding  the possibility of its implementation. In recent years, Mato Grosso has stood out on the international scene as an important agricultural center, especially in grain production. Such economic activity is strongly dependent on water for irrigation, aiming at yield improvement. Irrigation is the consumptive use that accounts for almost half of the water intake in the country. In Mato Grosso, as of 2016, there was an intensification of the  use of groundwater for irrigation of monocultures, especially due to the  fact that  some  regions in the center-north  of  the  State had  presented superficial  water unavailability,  according  to  the  adopted  criteria  for  concession.  This  pressure  on groundwater  resources  brings  to  light  some  worrying  factors,  among  them,  the absence  of  studies  and  technical  criteria  that  can  support  decision making  in  the management  for  effective  protection  of  these  waters.  In  this  context,  the  need  for investments,  including  financial  ones,  in  the  management  of  water  resources  is evident, which highlights the charging for water use in order to induce rational use and obtain resources for improved  management. In light of this, this work proposes an analysis of the  price  of water and  its  impact on  the  profitability of  the irrigator using  groundwater  in  the  Parecis  Aquifer and  the  charging’s  fundraising  potential, from the perspective of charging as one of the pillars for financial sustainability of the Water  Resources  System. The  analyzes  showed  the  importance  of  establishing  the price  of  water  considering  technical  criteria  and  local  specificities, since  the  prices already  practiced  in  Brazil  used  in  this  study  produce  a  minor  impact  on  the sensitivity analysis. It was also possible to identify that the charging models, in the context of this study, are capable of financing, for the most part,  only the  scenario that contemplates projects classified with medium and low priorities. Lastly, a draft law  was  drawn  up to regulate  charging  in  the  state  of  Mato  Grosso,  which  will be presented to SEMA for analysis. Due to the lack of studies on this issue in the State, it  is  expected  that  the  reflections  and  propositions  will  encourage  discussions  and assist in decision making of the entities of the State Water Resources System.

  • Mostrar Abstract
  • The interaction of the human being with the environment has been presented, by many authors, as the cause of the situation of environmental and water crisis of the present moment. These suggest that in order to understand the proportions of the current situation and try to seek solutions, it is first of all necessary to try to understand human behavior, its relationship with the environment and the way it perceives and acts in the environment. Knowing what motivates behavior change, which can either degrade, protect or conserve, implies understanding the individual's perception from his insertion and interpretation of the environment. Faced with the problems of the water crisis, quality and quantity, it is increasingly necessary to develop works that aim to understand the interaction of man with water resources, thus leading to study the environmental perception of the actors involved in the processes that influence the dynamics of streams urban. In this sense, environmental perception in its essence gathers sensory, cognitive aspects and emotional, which act on the environmental reality to which the individual is inserted. The objective of this research was to study the perceptions of the residents of the banks of the Garrucha stream, in relation to environmental issues in order to present an educational intervention proposal. The research was developed in the city of Araputanga-MT in the urban perimeter. The methodological approach used in conducting the research was qualitative, through a single case study and interview technique with 40 residents who live on the banks of the stream. In this way, the results obtained allowed the elaboration of an educational intervention proposal with the residents, based on the perceptions of the residents. In this perspective, the proposal extends to seeking partnerships with educational institutions and a river basin committee and other bodies for the possibilities of mitigating the stream's environmental problems through environmental education.

  • Mostrar Abstract
  • Due to the constant population growth around the world, it is expected that the use of water will continue to increase proportionally to it and concerning other factors such as climate change and the emergence of new social standards. These factors bring up the need to evaluate how water management is practiced nowadays. In order to obtain efficient results in this sense, it is pertinent to consider an innovative approach of water resource management that is sensitive to economic, social and environmental parameters. New approaches, responsive management, and innovation in the public service are essential components to achieve water security that guarantees the availability of water in sufficient quantity and quality to meet human needs, the practice of economic activities and environmental conservation, that are ideal for dynamics of the city administration. For its abundance of water resources, the state of Mato Grosso is known as the State of Waters, where there are placed three of the twelve hydrographic regions in Brazil, in addition to the Metropolitan Region of the Valley of Cuiabá River, a region where events related to the inefficient management of urban water are growing, such as floods, floods, pollution of water bodies, increased risk of contamination by waterborne diseases, reduction of areas of permanent preservation, lack of care in basic environmental sanitation services, among others. This work has as main objective to raise conditions of the application of integrated management of urban waters for the city of Cuiabá, through techniques of Nature-based Solutions (SbN) aiming control of runoff of rainwater in retention devices and infiltration, to the municipality of Cuiabá, with a view to the legal framework, the history of urban occupation and sanitation in the municipality, the available water resource, and its predominant uses, and the municipal public management. The practical product of this dissertation will be a draft of a legal instrument of municipal authority, whose objective is to regulate the application of structural measures based on the concepts of NbS. To achieve the objectives of this paper consultations were held on the legal framework related to urban drainage and basic sanitation in the city of Cuiabá, also to official data on demand and quality of service, in addition to bibliographic research. Given the research and data from the municipalities, an analysis of the structure and model of integrated planning for urban water management was carried out and these methods of success can be used in public management in Cuiabá and also what are the tools used to achieve it.

  • Mostrar Abstract
  • In the water resource management process, the participation of the various sectors is of fundamental importance for guaranteeing water in quantity and quality in view of its multiple uses. This implies a series of processes and steps that will support decision making by the collective, reflecting the entire hydrographic basin management unit in the integration and articulation of all the activities that need and impact water resources, in order to ensure availability , sustainability and conservation. In this context, the institutionalized legal frameworks advocate the guarantee of water for all forms of life prior to the desires of the productive market, Law No. 9,433 of 1997, establishes a series of regulations and structures to strengthen the integrated management of water resources, among which the creation of hydrographic basin committees (CBH´S), with decentralized and participative management, with the hydrographic basin as a territorial management unit, for decision making in each hydrographic region aiming to meet the different specificities. This work aimed to analyze the perceptions of the members of the hydrographic basin committees, of the Cabaçal River and of the Jauru River, located in the southwestern portion of the State of Mato Grosso, about the governance of water resources. Qualitative, descriptive, exploratory, this research analyzed the governance processes of CBHs Rio Jauru and Cabaçal. The results show that with respect to participation processes, representatives of civil society, the government and water users are part of it, yet both committees have a high number of absences at meetings, one of the challenges is the geographic size of the basins that requires effort from all members participating in the management of water resources in the basin. There are no management instruments in place, it is worth considering that the committees are recent and are being restructured, training is needed to support the councilors to become familiar with the watershed and the management system. The committees do not have a deliberative function, only the State Water Resources Council has this function, a different framework from the national policy that establishes deliberations for the hydrographic basin committees. The challenge is to make these spaces participatory and include the different actors, so that they can actually plan and regulate the management of water resources whose results are reflected in the conservation of water resources in the hydrographic basins of the Jauru and Cabaçal rivers.

    CUIABÁ RIVER WATER QUALITY MODELING TO EVALUATE THE CONTROL OF DIFFUSED POLLUTING
  • Orientador : RODRIGO BRUNO ZANIN
  • Data: 20/11/2020


  • Mostrar Abstract
  • The Upper Rio Cuiabá Watershed, bounded by the Planning and Management Unit P4 (UPG-P4) and located on the plateau of the Hydrographic Region of the Paraguay River (HR-Paraguay), presents itself as a point of high interest for water quality control, since it encompasses the most populous and densest region of HR-Paraguay (with about one million inhabitants), it has a growing expansion of the agricultural and livestock sectors and is located upstream of one of the largest extensions of wetlands in the world: the Pantanal. Among the main causes of the water quality problems observed in HR-Paraguay are the transport of sediments and diffuse rural polluting loads from the plateau region to the Pantanal. Thus, this work aimed to evaluate the impact of the implementation of alternatives to control phosphorus present in the diffuse loads of the UPG-P4 on the water quality of the Cuiabá River. Using the HEC-RAS software to perform a one-dimensional stationary modeling, four water quality scenarios were simulated: (i) Base Scenario: flows during flood periods without diffuse load reduction; (ii) Scenario 1: flows during flood periods with an 80% reduction in phosphorus concentrations in pasture and agricultural areas; (iii) Scenario 2: flows during flood periods with an 80% reduction in phosphorus concentrations only in pasture areas; (iv) Scenario 3: flows during flood periods with an 80% reduction in phosphorus concentrations only in agricultural areas. The results showed that the phosphorus limits established by CONAMA Resolution nº 357/2005 were reached only in Scenario 1, and only in the stretch between the Manso River and the beginning of the urban area of Cuiabá. It was observed that, in the study area, the impact of pasture areas is more significant than agricultural areas. However, the configured model proves to be useful as a tool for making decisions related to the planning of water quality control, and can be used for the evaluation of various combinations of solutions and scenarios at UPG-P4 and with the potential to be replicated in other regions of HR-Paraguay, as long as the necessary adaptations are made. With it, it is possible to study alternatives that can reach the limits established by the legislation. However, it is important to carry out a critical assessment of the real impacts and improvements that meeting the maximum concentrations required by the CONAMA resolution would bring to the dynamics of the Pantanal. To this end, complementary studies would be needed to assist decision making within the scope of the Paraguay River Hydrographic Region.

  • Mostrar Abstract
  • It is estimated that in Brazil only 51.9% of the population has sewage system care and only 44.9% of the sewage generated in the country goes through some treatment process. In this context, it is necessary implementing alternative technologies in order to mitigate the difficulties that the basic sanitation sector faces. Thus, it is essential to choose an adequate system for the treatment of effluent, especially in regions such as the State of Mato Grosso that still has a large area that needs care. Built Wetlands have proven to be versive and efficient in reducing elements such as Suspended Solids, Chemical Oxygen Demand (DQO), Biochemical Oxygen Demand (DBO), Ammoniacal Nitrogen, Total Phosphorus, Nitrate and Nitrite. The removal of these pollutants takes place through mechanisms of filtration, adsorption, sedimentation, decomposition, microbial metabolism and metabolism of aquatic plants.  The present work aims to verify the efficiency of a Wetland Built bench for the treatment of synthetic sewage. In this sense, it was verified that the synthetic sewage obtained a significant reduction in the parameters of DQO, DBO, Ammoniacal Nitrogen, Total Phosphorus, Nitrate and Nitrite after passing through the WC system. Therefore, the studied alternative systems demonstrated viability for the treatment of synthetic sewage, presenting itself as a promising alternative for the treatment of effluents, in order to collaborate with the greater scope of sewage treatment in the communities.

  • Mostrar Abstract
  • Most cities appear and evolve the margins of water courses, as these supply several demands, such as domestic needs, transportation, economic, cultural activities and other uses, which promote changes in urban water courses, changing their morphology and shapes originals. The city of Rondonópolis-MT has about 06 (six) urban rivers, the largest being the Arareau River. The present work arises from questions about the impacts that permeate the urban section of the Arareau River, the current situation of the river and what measures can help in mitigating the damage that occurs in the Arareau River? The objective was to diagnose the situation of the Arareau River taking into account the use and occupation of its banks in relation to the demographic growth of the city and whether there is monitoring of the quality of the waters of this river. For the analysis of land use and occupation, the comparison of satellite images obtained by Google Earth over an interval of 14 years (2004 to 2018) was used. Eight (8) points were selected for on-the-spot verification and collection of water samples, which underwent X-ray Fluorescence Spectrometry analysis. The results obtained showed a diagnosis of changes both in land use and occupation and in water quality. of the river, indicating the need for intervention by the public administration and the other entities of management and regulation of water resources, regarding environmental care and water quality. The product developed as part of this research was an action plan to mitigate the problems encountered, aiming to regain access to natural resources, in order to allow the population to revive the culture that is in the collective memory of the population, reaffirming the need for creation, expansion and application of actions that minimize these impacts.

  • Although the Pantanal is well known for being the largest humid area on the planet, during the dry season, the water resource is scarce in some points, even compromising the feasibility of installing families and raising animals in the region. To change this perspective, the initiative to use social technologies to capture and store rainwater, changed the characteristics in a small part of a region lto Pantanal in the municipality of Cáceres-MT. The study area is the Rancho da Saudade, which has 47 families, where small dams, called Barraginhas, since 2011, whose function is to improve the supply of drinking water animal and plant production. This work is characterized as an exploratory study descriptive, having the Rancho da Saudade settlement as a universe of research and as object of study the families of the locality. The research sample consisted of forty-six seven family units, with a semi-structured interview data collect. It is expected with this research, to try to understand the transformation that occurred in the lives of families based in Rancho da Saudade in Cáceres-MT, with the process of construction of barraginhas to the present day, from the perspective of the settled population. The specific objectives of the project will be (i) - Analyze the perceptions of residents of the Rancho da Saudade settlement in relation to the contributions of barraginhas technology; (ii) - Analyze the quality of water use in the Rancho da Saudade settlement; (iii) - Prepare an educational proposal for the dissemination of barraginhas social technology, contributing to replication in other rural communities. As a product, research is interested in specific analysis of the quantitative and qualitative data referring to the change in the family farmer, in the border region, in the municipality of Cáceres-MT, disseminating and socializing the results of the research with the community involved, government agencies and other bodies linked to family farming, providing technical subsidies for the management of water resources in settlement areas.

  • Mostrar Abstract
  • The population increase directly impacts the generation of solid waste, compromising the quality and multiple uses of water bodies, especially those located in the area of influence of Final Solid Waste Disposal Centers (RDFRS), since leachate or leachate contains substances highly soluble and toxic. What environmental impacts does the landfill cause for the Ribeirão do Lipa basin and surroundings? The objective of this work was to evaluate the environmental quality of the area of influence of the Final Disposal Center for Urban Solid Waste (CDFRSU) in Cuiabá, MT. The study area is the Cuiabá Municipal landfill Located on the Balneário Letícia road, s / nº, Sítio Quilombo, inserted between the microbasins of Ribeirão do Lipa (RL) and Córrego Doutor (DR) and Córrego Três Barras (TR), which are constituents of the Coxipó River sub-basin, belonging to the Cuiabá River Basin. This investigation was based on the analysis of legislation on Integrated Management and Planning of Water Resources and Solid Waste, Digital Cartographic Base - MMA / DSG; physical chemical data from Ribeirão do Lipa provided by the Secretariat of the Environment (SEMA); field observations and the use of an unmanned aerial vehicle (drone). In the region there was an increase in land use and occupation (1984 to 2017), due to urban expansion, but it maintained a high rate of vegetation cover, less around the Municipal Landfill of Cuiabá-MT, with areas with little or no vegetation. The data on the physical and chemical variables of Ribeirão do Lipa, indicated that the variables BOD and O2 showed values above the limits established in CONAMA Resolution nº 357/2005, an indication of the presence of organic matter, which promotes the alteration of the physical-chemical parameters of water quality, can kill fish and eliminate other aquatic organisms. The leachate flows through the soil without any containment or treatment measures, reaching adjacent watercourses such as Ribeirão do Lipa, with consequences not yet measurable on the impacts associated with heavy metals in the leachate composition. It is noteworthy that spaces built to be manure lagoons were observed, due to the aspect of which they were never used. Solid waste collected in the city is exposed to the open sky, and the coverage of solid waste does not occur entirely. There is the presence of recyclable material collectors without any protection measure (IPI, access to drinking and bathing water) and residents in the landfill's area of influence, which is illegal. The relationship between the management of water resources and solid waste requires an articulation between the two sectors, especially in the urban environment, to minimize direct and indirect impacts on the drainage basin where the Cuiabá Landfill is installed. It emphasizes that the term “sanitary landfill” is far from meeting the basic requirements for such classification, conceptually, the indicators classify between Lixão and Controlled Landfill, both distant from the Solid Waste Law (11,445 / 2007). In this perspective, an integrated management plan for the area is proposed, taking into account environmental and social risks, especially human health, and to comply with Law No. 12,305 / 2010, which established deadlines for the adequacy of the disposal of solid waste, extended to 2021 (in cities the size of Cuiabá). It is expected that the plan will contribute to decision-making by the competent bodies, in order to comply with the law, which aims to maintain a balanced environment for current and future generations.
