RESUMO:

The river channels correspond to important landscape elements in the context of cities. Due to industrialization and consequently the acceleration of urban expansion, they have undergone intense environmental changes in their natural courses. This same process occurred in the urban river channels of the city of Manaus - Amazonas. In view of this, the present dissertation has as its object of study the hydrographic sub-basin of the Cachoeirinha creek. The study aimed to analyze the process of use and occupation, hydrodynamics and the impacts on the river channel in the Igarapé da Cachoeirinha, in the city of Manaus, Amazon. For the development of the study, the organization in stages was used, which were the bibliographic survey, cartographic survey, analysis of secondary data, monitoring of hydrodynamic variables, application of protocols in the defined sections and later the systematization of the data. The igarapé drainage network underwent several alterations (widening, canalization, rectification) in the riverbed, mainly in the medium and lower course. Through changes in river processes, associated with dense urbanization in the surroundings, eight sections in poor condition, one in fair condition and one in good condition were identified. The only section that is in good condition is located in the source area, in the upper course of the channel. However, it is possible to state that the sub-basin, from section 3 onwards, is altered and impacted at different levels. Still, through the analysis of bathymetric data, the period with the lowest flows is in the ebb, but the channel had zero flow in section 1, ebb period, as well as in section 10, in the flood period, considering that this section also receives influence the flood of the Rio Negro. The width increases from upstream to downstream showing variations between the two studied periods. Finally, measures are needed to mitigate the various impacts on the Cachoeirinha stream, thinking about the sustainability and environmental diversity that the channel exerts in the general context.
