Analysis and Recovery Proposal for Erosion Process Located in the City of Planaltina-GO
The rapid process of growth of urban areas in the country, with disorderly occupations with little care to the physical environment, has caused serious erosion and numerous problems. In the central region of Brazil, in particular, in the Planaltina city in the state of Goiás, the situation is not very different, requiring urgent interventions aimed at the recovery of degraded areas. As striking consequence of the disorderly occupation is the erosion, which occurs without distinction on the various geomorphological domains present in the Midwest. Thus, erosions generate various economic social consequences such as loss of inhabitable or cultivable areas, pathways interruption, silting of the riverbed of watercourses, exposure of the public and private equity and risks to nearby communities, common facts also to other cities and constantly aired in the media. used urban occupations practices have been one of the main causes for the intensification of erosion processes around these areas. The removal of native vegetation, soil sealing and destination rainwater without necessary care can modify the flow regime active with the resulting upwelling of erosive processes. In this context, an erosive process large located in the city of Planaltina / GO evolves over two decades mainly due to the advancement of human occupation combined with little drainage systems consistent with the local situation, but also the lack of appropriate interventions that have contributed for converting slopes with high risk of instability and to surrounding areas. Thus, it is of paramount importance to know, among other factors, the origin and evolution of the erosive process in question, the type of local soil, environmental changes caused over time in the study area with a view to proposing interventions can be efficient recovery of the area degraded by erosion. Therefore, this article seeks to present an analysis and proposed recovery for the erosive process in question in order to use the area to be recovered for leisure, sport, education, among others.
