Abstract

This study aimed the morphometric characterization of Corrego Guassu catchment, a watershed used for water supply for human consumption in Mundo Novo, MS municipality, which has problems concerning the water availability during the drought season. Free GIS software were used to obtain and process spatial data. Thus, the catchment delineation and the morphometric characteristics were obtained automatically using the softwares gvSIG and QuantumGIS, respectively. The catchment area was found to be 62.75 km², its shape is elongated, with lower flooding vulnerability in normal conditions of rainfall, low drainage density and smooth-rolling relief. As a solution to the problems of water lacking, we suggest the construction of a reservoir in the actual outlet. Lastly, the employed free GIS accomplished the tasks purposed by this study in a satisfactory way.
