Análises morfométricas e fisiográficas de sub-bacias hidrográficas na Bacia Alto Paranapanema

Abstract

Water is an essential resource for life, playing a vital role in ecosystems and anthropogenic activities. Due to the improper use of water resources, population growth, and inefficient planning, water has become a scarce resource. The study of the morphometric characteristics of these basins is crucial for the sustainable management of water resources, identification of vulnerable areas, and prevention of water-related disasters such as droughts and floods. Thus, this study aims to analyze 12 sub-basins of four different landscape matrix types in the UGRHI 14 - Alto Paranapanema: forest, pasture, agriculture, and urban area. The analysis considered physiographic, morphometric, and land use aspects, using parameters such as: form factor (Kf); compactness coefficient (Kc); circularity index (Ic); drainage network frequency (Dr); sinuosity of the main river (Sin); drainage density (Dd); texture ratio (T); average basin slope (H); relief ratio (Rr); elongation ratio (Re), average surface runoff extension (l), and finally, the roughness index (Ir).
