Aplicação de uma ferramenta SIG para caracterização morfométrica de uma bacia hidrográfica: estudo de caso da microbacia de Itapagipe na região de Salvador-BA

Abstract

This paper addresses the importance of morphometric characterization of river basins, with emphasis on the Itapagipe basin, located in Salvador, BA. W atersheds are areas delimited by topographic dividers, and the analysis of their morphometric analysis of their morphometric parameters, such as area, perimeter and shape indices, helps to understand their hydrological behavior and identify risks, such as flooding. Inadequate urban planning and increasing urbanization aggravate these risks, especially in storm drainage areas. The research proposes the use of QGIS software, a Geographic Information System (GIS), to carry out a morphometric analysis of the Itapagipe basin. Based on geospatial and topographical data, the software makes it possible to calculate parameters, generate maps that help with urban planning and indicators for assessing the risks that may exist in the basin.
