Resumo: | The present article aims at the mapping of the Geomorphologic Units of the Hydrographic Basins of the Jaguari Mirim, Inhadiju, and Piquiri Streams, located in the west of Rio Grande do Sul – Brazil. Data analyzes defined six units characterized as: Unit I – Plane Top Relief in Volcanic Spill: shows plane relief with relatively low erosive processes and intemperism; Unit II – Hills in Volcanic Spill: slightly wavy areas underneath the plateau summit; Unit III – Hills and Small Size Hills in Volcanic Rock: formed by strongly wavy relief and with scarps; Unit IV – Small Size Hills in Sandstone: composed by isolated small size hills with origin associated to the existence of united sandstones that keeps the plane top relief; Unit V – Hills in Sandstone: Relief of hills located at the medium and low course of the streams, with the occurrence of accelerated erosive processes which produce sand dunes and accelerated erosions, and sometimes with the blooming of united sandstones in the half-slope or in the top; Unit IV - Plane Relief in Low Altitude: Relief of plane topography that predisposes the superficial dynamic processes, generating the accumulation of sediments as well as the formation of fluvial terraces. The fragility of the natural systems, in face of the antropic interventions, is largely associated to its genetic characteristics. Thus, the geomorphologic analysis in the environmental studies is a tool for the maintainable planning of the activities introduced in the region. |

Este artigo objetiva o mapeamento de Unidades Geomorfológicas das Bacias Hidrográficas dos Arroios Jaguarí Mirim, Inhadiju e Piquiri, localizadas no Oeste do Rio Grande do Sul - Brasil. As análises dos dados definiram seis unidades caracterizadas como: Unidade I - Relevo de Topo Plano em Derrame Vulcânico: apresenta relevo plano com processos erosivos relativamente baixos e intemperismo; Unidade II - Colinas em Derrame Vulcânico: constituem-se as áreas suavemente onduladas sob o topo do Planalto; Unidade III – Morros e Morrotes em Rocha Vulcânica: formado por relevo fortemente ondulado e com escarpas; Unidade IV - Morrotes em Arenito: composta por morrotes isolados com origem associada à existência de arenitos coesos que mantém o relevo de topo plano; Unidade V - Colinas em Arenito: relevo de colinas localizadas ao médio e baixo curso dos arroios, com ocorrência de processos erosivos acelerados gerando areais e voçorocas, às vezes com afloramentos de arenitos coesos na meia encosta ou no topo; Unidade IV - Relevo Plano em Baixa Altitude: relevo de topografia plana que predispõe os processos de dinâmica superficial gerando acumulação de sedimentos e a formação de terraços fluviais. A fragilidade dos sistemas naturais, face às intervenções antrópicas, está amplamente ligado às suas características genéticas. Desta forma, a analise geomorfológica nos estudos ambientais é uma ferramenta para o planejamento de forma sustentável nas atividades implantadas na região.UFPRTrabalho realizado com apoio FAPERGS n° 05/18123 – CNPq 470432/2006-3.Righi, EléiaRobaina, Luis Eduardo de Souza2009-10-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufpr.br/raega/article/view/1208910.5380/raega.v18i0.12089RA'E GA Journal - The Geographic Space in Analysis; v. 18 (2009)RAEGA - O Espaço Geográfico em Análise; v. 18 (2009)2177-27381516-413610.5380/raega.v18i0reponame:Ra'e Ga (Online)instname:Universidade Federal do Paraná (UFPR)instacron:UFPRporhttps://revistas.ufpr.br/raega/article/view/12089/10959info:eu-repo/semantics/openAccess2018-07-05T19:27:37Zoai:revistas.ufpr.br:article/12089Revistahttps://revistas.ufpr.br/raegaPUBhttps://revistas.ufpr.br/raega/oai||raega@ufpr.br2177-27382177-2738opendoar:2018-07-05T19:27:37Ra'e Ga (Online) - Universidade Federal do Paraná (UFPR)false |
