Resumo

A detailed study of watersheds is essential for environmental and territorial planning, as well as for the sustainable management of water resources. In this context, morphometric analysis is an effective tool for identifying a basin's predisposition to erosion and flooding processes. This study presents a morphometric analysis of the Corumbataí River Basin, located in the Center-East region of São Paulo State, Brazil. The basin supplies nine municipalities and holds strategic importance due to intensive agricultural, industrial, and urban activities. Dimensional parameters, drainage patterns, and relief characteristics were analyzed using SRTM data and Geographic Information Systems (GIS) tools. The results indicate a low propensity for flooding, moderately dissected relief, and low drainage density, which point to limited water availability. The roughness coefficient identified areas with high susceptibility to erosion, in contrast with the current land use, which is predominantly characterized by sugarcane cultivation and clay mining. Morphometric analysis proved to be effective in identifying environmental vulnerabilities and providing valuable support for the development of land-use and conservation policies that are more compatible with the basin?s natural characteristics, reinforcing its potential as a tool for integrated environmental planning.
