| description | Environmental studies, seeking knowledge of resources and the weaknesses do part of the work of Environmental Geology Laboratory (LAGEOLAM – UFSM) during the past 15 years. The west-southwest of Rio Grande do Sul represents an area of great environmental degradation with accelerated processes of erosion, gullies, and sands process. This paper analyzes and maps geo-environmental units in Itu River basin, using a mapping scale of 1:50,000. The components represent a geo-environmental interaction between the characteristics of the physical environment (topography, geology, drainage, soils, precipitation, surface features) and the use and occupation of land. The work defined 9 units as those with homogeneous characteristics from dynamic surface processes, which are: unity of recent deposits, sandstone hills, hills of volcanic rocks, flat tops, sandstone buttles of the sandstones, buttles of volcanic rock, steep topography, urban use, processes of sands. This map serves as a tool in regional development projects and resource management. |

Os estudos ambientais, que buscam o conhecimento dos recursos e as fragilidades do meio, fazem parte dos trabalhos do laboratório de geologia ambiental (LAGEOLAM – UFSM) durante os últimos 15 anos. O oeste-sudoeste do estado do Rio Grande do Sul representa uma área de grande degradação ambiental com acelerados processos de erosão, voçorocamento, e processo de arenização. O presente trabalho analisa e mapeia unidades geoambientais na bacia hidrográfica do Rio Itu, usando uma escala de mapeamento de 1:50.000. Os componentes geoambientais representam uma interação entre as características do meio físico (relevo, geologia, drenagem, solos, precipitação, feições superficiais) e o uso e ocupação da terra. Foram definidas 9 unidades com características homogenias quanto aos processos de dinâmica superficial, que são: unidade de depósitos recentes, colinas de arenito, colinas de rochas vulcânicas, topos planos, morrotes de arenito, morrotes de rocha vulcânica, relevo escarpado, uso urbano, processos de arenização. Este mapa serve de ferramenta em projetos de desenvolvimento regional e gerenciamento de recursos. 2012-07-18 2022-03-17T15:13:43Z 2022-03-17T15:13:43Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://www.revistas.usp.br/rdg/article/view/47214 10.7154/RDG.2012.0023.0012 http://biblioteca-repositorio.clacso.edu.ar/handle/CLACSO/41849 por https://www.revistas.usp.br/rdg/article/view/47214/50950 Copyright (c) 2012 Romario Trentin, Luís Eduardo de Souza Robaina application/pdf Universidade de São Paulo.
