INTEGRATED ANALYSIS MIDDLE PHYSICAL LIKE SUBSIDY FOR THE DIAGNOSTIC OF PROCESSES EROSIVE ON BASIN OF THE EXTREMA LARGE CREEK IN ANÁPOLIS (GO)

Abstract

Currently, in changeable scale, the Brazilian cities present common problems, derivatives of the intense modifications suffered in previous and aggravated decades throughout the years, for the lack of planning and control of the use of the land. In the city of Anápolis-GO, the use of lands, did not take in consideration the fragilities of the environment where if it inserted, conditioning the city problems of environmental order, that if they reflect in the occurrence of linear erosive processes, silting and floodings. The basin of Extrema large creek is one of the areas of Anápolis with this type of environmental problem. Ahead of this, the present work investigated the relation between the constraints of the environment, including its use and the occurrence of linear erosive processes in this hydrographic basin. It is based on the integrated analysis of the components of the nature and the society, made possible with the aid of the geoprocessing technologies. The results obtained show that the distribution of the erosive focus is associated in such a way with both to natural conditions as anthropic. The erosions are mainly located on forms of relief with slope greater than 10%, covered by latosoil and Cambisoils, developed from rocks of the complex Granolithic Anápolis-Itauçu and in the group Araxá in south of Goiás, where the use of the land has no infrastructure appropriate.
