“…Dessa forma, é possível compreender que parâmetros morfométricos podem subsidiar a formulação, o planejamento e a tomada de ações quanto à fragilidade ambiental de áreas de interesse (Costa et al, 2020). Contudo, há de se considerar que somente o coeficiente de rugosidade não revela o verdadeiro potencial de uso do solo (Oliveira et al, 2013), sendo recomendável que haja um aperfeiçoamento dessa análise observando dados pedológicos, climáticos e socioambientais.…”

The hydrographic basins are of great importance in environmental studies, as their components are interconnected and the alteration in any of them can generate a great impact in the region in which it is located. Therefore, this research aimed to analyze morphometrically the Carapiranga river watershed, located in the municipality Registro (SP), Brazil, using geoprocessing techniques to obtain physical data of the watershed that support management and planning actions. For this, the geoprocessing techniques used topographic maps provided by the Geographical and Cartographic Institute (GCI) to perform the morphometric analysis. The results showed that the watershed covers an area of 68.88 km², a perimeter of 75.71 km, has a more elongated, and less circular shape, and the watercourse presents up to the 4th order. The parameters of circularity index (0.17), compactness coefficient (2.39), and sinuosity index (1.24) demonstrated that the basin has good drainage, as it has medium permeability and high infiltration. It is noteworthy that the roughness coefficient indicates that a large part of the basin is suitable for agriculture, main economic activity of the region, especially banana production, as this basin does not have areas with steep slopes, which attenuates water erosion.

Human land use land cover changes (LULCCs) can cause impacts on watershed lands and on water resources. The regions with land use conflict suffer more intense erosion processes due to their high slope and drainage density. The study intends to evaluate scenarios with an absence of land use conflict and verify if it can contribute to reductions in surface runoff, avoiding the carriage of tailings to river channels. In the study, the SWAT model was used in the hydrological modeling of the Paraopeba River watershed affected by the rupture. The results show that the SWAT model was able to reproduce the flow data with good and very good performances. The quality indicators in the calibration step were NSE = 0.66, R2 = 0.69, PBIAS = 5.2%, and RSR = 0.59, and in the validation, step were NSE = 0.74, R2 = 0.77, PBIAS = 13.5%, and RSR = 0.51. The LULCC from 2000 to 2019 led to a 70% increase in lateral runoff (LATQ) and a 74% decrease in aquifer groundwater. The scenario of land use capability and no conflict can reduce lateral runoff by 37% and increase water infiltration by 265%, minimizing the point and diffuse contamination of the tailings in the Paraopeba river channel.
