Zoneamento geoambiental da bacia hidrográfica do rio Ibicuí da Armada - RS: potencialidades e suscetibilidades

Abstract

The study area, represented by the river Basin Ibicuí of the Armada (BHRIA), located in the southwest portion of the state of Rio Grande do Sul. Stretch your area on portions of three major cities in the state, they are: Dom Pedrito, Santana do Livramento and South Rosary. Overall objective of this work is a geo environmental zoning, using as input information relating to the physical environment and the use and occupation. The rationale for choosing BHRIA, was the fact that present significant cases of superficial and economic dynamics, besides being an area rich in terms of geology, hydrology and geomorphological features. The number of work with this theme are still rarefied in this region. The term "zoning" in the proposal developed in LAGEOLAM / UFSM, refers to the installment of a given geographical area and has its direction in determining the weaknesses and environmental potential of landscapes. The definition of a homogeneous environmental unit may use a single parameter or a group of them to form one unit, which is the basis for analysis of an area. Parameter is defined as the basic element that is inserted and handled on a cartographic document, such as information that is part of the environment components. The theoretical assumptions that guide the research related to geoenvironmental studies focus on systemic character information, dealing with the integration of elements of nature and society spatialized form. The diagnosis provides information relating to natural and man-made features that comprise the study area, indicating potential and susceptibilities of systems and units. This paper presents information that can be used as territorial planning tools, as well as serving as a subsidy as the basic education of people in cities that occupy the watershed.
