Resumo: | The objective of this research was to predict soil loss due to laminar erosion in the Ribeirão Bocaina watershed (BHRB), located in the municipality of Passos-MG. The prediction was performed using the Universal Soil Loss Equation (USLE). The factors of the physical and anthropic environment influencing the water erosion process considered were: erodibility, erosivity, topography and vegetation cover and conservation practices. All factors were integrated and spatialized in the Geographic Information System (GIS), with the aid of geoprocessing techniques. As a result, Current Potential to Erosion (CPE), presented 55.4% of the total area of BHRB with soil losses below 10 t.ha-1.year-1, with a predominance of the “light” class and 44.6% of the area with losses greater than 10 t.ha-1.year-1 with a predominance of the “very high” class. There are areas with high soil losses, mainly in areas of agricultural crops, with soils more susceptible to erosion and steep slopes. The use of EUPS for the qualification of areas vulnerable to erosion showed advantages and showed an effective tool to assess the vulnerability to soil erosion and to assist in environmental and conservation planning of the use of the soils and water resources of the Ribeirão Bocaina River Basin. |

A modelagem foi realizada por meio da aplicação da Equação Universal de Perdas de Solos (EUPS). Os fatores do meio físico e antrópico influentes no processo de erosão hídrica considerados foram: erodibilidade, erosividade, topográfico e cobertura vegetal e práticas conservacionistas. Todos os fatores foram integrados e espacializados no Sistema de Informação Geográfica (SIG), com auxílio de técnicas de geoprocessamento. Como resultados, o Potencial Atual à Erosão (PAE) apresentou 55,4% da área total da BHRB com perdas de solo menores que 10 t.ha-1.ano-1, com predomínio da classe “ligeira” e 44,6% da área com perdas maiores que 10 t.ha-1.ano-1 com predomínio da classe “muito alta”. Há locais com perdas de solo elevadas, principalmente em áreas de culturas agrícolas, com solos mais suscetíveis à erosão e declividades acentuadas. A utilização da EUPS para fins de qualificação de áreas vulneráveis à erosão apresentou vantagens e mostrou uma ferramenta eficaz para avaliar a vulnerabilidade à erosão do solo e auxiliar no planejamento ambiental e conservacionista do uso dos solos e recursos hídricos da Bacia Hidrográfica do Ribeirão Bocaina.EDUFU - Editora da Universidade Federal de Uberlândia2022-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado pelos paresapplication/pdfhttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/5913010.14393/RCG238759130Caminhos de Geografia; Vol. 23 No. 87 (2022): Junho; 153–174Caminhos de Geografia; Vol. 23 Núm. 87 (2022): Junho; 153–174Caminhos de Geografia; v. 23 n. 87 (2022): Junho; 153–1741678-6343reponame:Caminhos de Geografiainstname:Universidade Federal de Uberlândia (UFU)instacron:UFUporhttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/59130/33961Copyright (c) 2022 Letícia Bueno de Oliveira Rocha, Rômulo Amaral Faustino Magrihttp://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessRocha, Letícia Bueno de Oliveira Magri, Rômulo Amaral Faustino2022-07-25T12:30:51Zoai:ojs.www.seer.ufu.br:article/59130Revistahttps://seer.ufu.br/index.php/caminhosdegeografia/indexPUBhttp://www.seer.ufu.br/index.php/caminhosdegeografia/oaiflaviasantosgeo@gmail.com1678-63431678-6343opendoar:2022-07-25T12:30:51Caminhos de Geografia - Universidade Federal de Uberlândia (UFU)false |
