Caracterização morfométrica da bacia hidrográfica do rio Meia Ponte no Centro-Sul de Goiás

Abstract

The Meia Ponte River Basin, which supplies important urban and industrial centers, faces challenges related to water scarcity, requiring detailed studies for effective resource management. Through the analysis of morphometric parameters such as area, perimeter, compactness index, drainage density, and slope, it was possible to understand the basin's hydrological dynamics and its influence on the distribution of water resources. The results show that the basin has an elongated shape, a characteristic that reduces flow concentration and the likelihood of major floods. Thus, the topographic analysis reveals a predominantly flat terrain, which, combined with the high sinuosity of the drainage network, directly impacts water concentration time and the risk of localized flooding. Additionally, the study highlights the importance of the Cerrado vegetation, predominant in the area, for maintaining water quality and availability. The study concludes that sustainable management of the basin's water resources must consider these morphometric factors, aiming to mitigate the impacts of human activities and preserve biodiversity.
