| Abstract | |
This work presents a method of analysis and compartimentalization of the environment that combines the subdivision in Ottobacias (Pfafstetter, 1987) with engineering geological mapping. Initially the basin was divided in 9 areas, represented by the 4 larger Pardo river sub-basins and the remaining 5 areas called interbasins. Furthermore, the characteristics of the attributes, rocky substratum, unconsolidated materials, slope, drains and landforms were obtained by engineering geological mapping and then analyzed in each one of these units. The areas that have not predominance of at least 70%, for the analyzed attributes, were subdivided until reaching this level of homogeneity. In the last stage, the obtained Ottobacias were regrouped in order to have compartiments with similarities at least 70%, considering the analyzed attributes. This compartimentalization leads to the attainment of 90 units. These units belong to 15 sub-groups which their aptitudes and geoenvironmental restrictions were further analyzed. This compartimentalization procedure and analysis were shown to be adequate for regional scales investigation, mainly in basins of great dimensions, as it is the case for the Pardo river basin. This compartimentalization and analyses provide bases for more detailed geoenvironmental studies. (AU) | |
