Abstract

In urban areas, the development of erosive processes can cause damage such as siltation of water sources, contamination of rivers, destruction of homes, undermining of foundations, silting of pipes, floods, reduced rural productivity and often loss of human lives. For any erosive feature, whether in an urban or rural area, when it is possible promote its recovery, a comprehensive analysis of the installed process must be carried out, observing the local conditions of the area that contributes to the appearance and development of the feature and the surrounding area. In this way, it presents at this article a broad study of the conditions that led to the formation and development of an urban erosive feature in Bauru City, enabling improved decision-making processes regarding solutions that should be adopted. The data were organized using the form for surveying conditioning factors and identifying erosive features, prepared by Mercaldi and Furegatti (2020). The erosive feature was classified based on the table developed by Mercaldi and Furegatti (2019) which identified it as a gully erosion.
