Abstract

The erosive processes, results of some physical phenomena, in many cases related to the human activities, cause soil loss and create an environmental vulnerability with loss of soil stability and fertility, negatively affecting the economy and the society. In order to mitigate and, when possible, to prevent the erosive processes, it is necessary, the knowledge of the physical and historical characteristics of the area. Therefore, in view of approval of the first Área de Proteção Ambiental, located in Bairro do Timburi, municipality of Presidente Prudente (SP), this assignment aimed to analyze the occurrence of erosion processes linear, and their geomorphological conditions. In this regard, several thematic maps were drawn up, having as a central point the forms of relief, and carrying out fieldwork to identify the areas most vulnerable to the development of erosion processes. As a result, it was identified that, of the 78 linear erosive features mapped, 48 (61.54%) are in concave slopes; 33 (42.3%) on a slope of 5-10%; and 55 (70.51%) related to agricultural anthropic areas.
