Analise Morfometrica de Bacias Hidrográficas: um estudo de caso da sub-bacia do Rio Mumbaba - PB.

Abstract

The following work consists of a morphometric analysis carried out on the Mumbaba River Basin, Gramame River sub-basin, located in Paraíba state, using the Qgis software, and applications of Geoprocessing techniques for the generation of data, by SRTM images, and Topographic Charts. By comparing the results synthesized from the MDEs, created by the SRTM images and Topographic Charts, so that the specific designation can be made, for the application of the appropriate models made according to the need for detail, financial budget and estimated time. to perform the analysis for a given project / action, following the Almeida 2007 methodology, for the production of morphometric parameters, such as form factor, circularity index, drainage density, for the diagnosis of flood probability, siltation risk, and for the determination of each model according to the need for forecasting future risks in the area, which may affect installations of a particular project made in the basin studied here.
