Análise Geoambiental aplicado ao estudo da vulnerabilidade à erosão na praia do Bispo/ Mosqueiro-PA

Geoenvironmental analysis applied to the study of vulnerability to erosion on the Bispo beach/Mosqueiro-PA

Abstract

Erosion is a very complex phenomenon, since it involves the direct or indirect action of several factors, such as geological and geomorphological characteristics, soil types, climate, vegetation, in addition to human interference that modifies the natural conditions of each one. from them. With this, this study proposed to generate a map of vulnerability to erosion of Praia do Bispo in Mosqueiro/PA, based on the intersection of geoenvironmental variables: geomorphology, geology, soil, vegetation, land use and climate. Using sources and data extracted from existing information, together with IBGE, INPE and EMBRAPA, which make Shapefiles (Vectors) available free of charge, from the State of Pará, where these data were treated, georeferenced and standardized. It obtained results from two types of scenarios: urban area and Forest. And with that, identified the points of erosion in the area, the first being the dynamic behavior and the second the conditions of the biophysical environment suffering the same impacts in their areas related to erosion.
