Mapeamento geomorfológico da área de influência do Escudo Sul-Rio-Grandense no Município de Pelotas/RS

Abstract

The science that has the relief as its object of study is the Geomorphology. It can be studied in many ways, including the geomorphological mapping, from which can be provided diagnostics and ambiental prognostics. The geomorphological mapping is the objective of this research, which is directed to the influence área of the Sul-Riograndense Shell in the city of Pelotas/RS. To the elaboration of this essay, stand out as theoretical and methodological basement, authors as Ab‟Saber (1969), Ross (1992, 2014), Florenzano (2008) and Rehbein (2011). The outlines of the relief features of the Sul-Riograndense Shell area of influence in the city of Pelotas were made; also the characterization of morphogenetic and morphocronological data; the characterization and cartographic representation of morphological data (morphometric and morphographic) and the characterization of relief‟s morphodynamic. In order to meet the outstanding objectives, were realized bibliographical reviews to understand the relief‟s genetic-evolutionary framework of the study area.Also includes the organization of a database of base cartography, necessary for the preparation of cartographic products, as well as the preparation of the map of use and land coverage. Finally, through field work, were identified and characterized the morphodynamics of the relief. Therefore, it was found that standarts on hills and alveolar plains predominate in this area of studies, also standing out the mapping of 1587 drainage headboards. One relevant aspect to highlight is the occuring of laminar erosion on the hills and hillocks, predominantly. There was also the siltation of river channels as a result of slope down riverbanks, devoid of riparian vegetation. Lastly, this research is considerated a resource to alert the local community about the ambiental impacts that surround them, besides servins as basis for planning politics. In addition, it is expected from that research – by its produced products – that it contributes to educational establishments in the city of Pelotas and region, providing more detailed information about the local geomorphology.
