Compartimentação do relevo baseada em parâmetros morfométricos: uma análise da região do extremo oeste da Bahia

Abstract

The remote sensing and geoprocessing techniques have become optimising technologies for environmental studies and various other fields of science. The study presented here aims to identify the areas with the most significant susceptibility to dissection and after that to enable further analysis, especially concerning environmental planning. For the development of the research was used the Global Relief Dissection Index, proposed from the use and overlapping of three geomorphometric parameters. The results showed that the areas most susceptible to dissection are in the transitional range between the Serra Geral plateau and the São Franciscan Depression, mainly where higher roughness concentrations occur.
