ANÁLISE MORFOMÉTRICA DE BACIA HIDROGRÁFICA UTILIZANDO DADOS DE DIFERENTES MODELOS DIGITAIS DE SUPERFICIE

Abstract

The morphometric analysis of the watershed is important to support the development of environmental studies. With the advancement of geotechnologies, Digital Surface Models (MDS), extracted from satellite images and processed in a Geographic Information System environment, have been an important source of data forthe morphometric analysis of basins. This study characterizes watershed morphometry using different MDS. The Pirapozinho river basin was adopted as the object of study. The findings of this work reveal a low propensity to flood the basin under analysis. Also, we note that there may be variations in the morphometric parameters according to the MDS used, even though they are models of the same spatial resolution.
