RESUMO:

Considering the damage that improper land use and occupation cause in river courses, the present work aimed to analyze the hydrodynamic and hydrosedimentological variables and the process of marginal erosion along the longitudinal profile of the Mineiro stream, located in Jauru, Mato Grosso, with a view to providing environmental information on the state of conservation/degradation of the area. The methodological procedures used were: bibliographic survey; field work in specific locations to measure the hydrodynamic variables, proceed with the collection of bottom and suspension sediments and the insertion of pins and stakes to monitor the process of marginal erosion. In the laboratory, analyzes were carried out to quantify the suspended load, the granulometry of the transported sediments and the composition of the soil on the banks. The process of colonization of the area began in the 1950s, in a disorderly way and based on the extraction of wood. Its main geo-environmental attributes are: relief with a gentle slope, presence of red yellow eutrophic argisols originally covered by seasonal forests and sub-humid tropical climate. With an area of 102.7 km², within the domain of the Mineiro hydrographic sub-basin, the urban area of the municipality of Jauru and part of its rural area are inserted, comprising several properties, in which the main economic activity developed is extensive livestock. Its main channel is the Mineiro creek, which together with its tributaries supply water to the entire population and economic activities carried out in the sub-basin. The results obtained made it possible to infer that the Mineiro stream is in the process of silting up, due to anthropic actions that suppressed the native vegetation for the introduction of livestock and that allowed the trampling of cattle on the banks of the watercourse. These factors led to soil compaction, increased surface runoff, fragility of the banks and the carrying of sediments into the river bed. Based on this information, it is concluded that it is necessary to implement actions that promote the protection, conservation and/or recovery of water resources in that locality. As part of the necessary actions, an Environmental Education project was developed on the subject in the state school inserted in the study area, based on the geography of perception whose aspect comes from phenomenology. In the 9th grade A and B classes, concepts related to watersheds were worked on and the data from this research were presented. From the individual perception, the students built mental maps about the Mineiro stream. Subsequently, the knowledge learned by the students was shared with the other classes, through the presentation of seminars.
