Abstract
-
This paper presents a study of the characteristics of the slopes that make up the relief in the Ibirapuitã River basin in the west of Rio Grande do Sul. The relief classification follows a geomorphometric automated mapping proposal presented by Silveira & Silveira (2013). The classification is performed by means of crossing information and topographic attributes generated by GIS and in a hierarchical decision tree. The crossing of information using the decision tree with the parameters of altitude, slope, curvature profile and plan identified 12 representative units in the basin. The cartographic product obtained suggests that the methodology is appropriate to characterize the slopes in study area and the spatial distribution of processes, with great potential for support in work relating the relief characteristics with other environmental attributes and land use.
