Abstract

Knowing the morphometric characteristics is essential to understand the hydrological behavior of a river basin and provide a diagnosis for conservation projects. Although this is a widespread topic, there are few current studies on the Japaratuba River Basin (JRB) with this theme. In this sense, this article aims to present a morphometric and geospatial characterization of the JRB, using the Digital Elevation Model (DEM) of the Shuttle Radar Topography Mission (SRTM) and the geoprocessing and remote sensing software QGIS. The morphometric parameters were calculated and maps of slope, land cover and soil types were created. Located in Sergipe, the JRB covers an area of ​​approximately 1674 km², a perimeter of 233.44 km and a main river with a length of 112.20 km. The results of the shape factor (0.32), compactness coefficient (1.6), circularity index (0.39) and elongation ratio (0.63) indicate that the BHRJ has a low tendency to flood under normal precipitation conditions due to its elongated shape. It has a medium drainage density (1.26 km/km²), in addition to a relief that varies from flat to strongly undulating, 19 land cover classes and 7 soil classes. Finally, the importance of this type of analysis to assist in the planning and management of water resources is highlighted.
