Resumo: | The objective of this study was to assess potential erosion in the stream Rico hydrographic sub-basin (SRHS), in order to support improvements in environmental conservation and economic productivity. The procedures took place in the ArcGIS® program, with the aid of a geographic database. SRHS was delimited with the aid of a Digital Elevation Model. The erosive potential was estimated using the Universal Soil Loss Equation, w.ith the parameters: slope, ramp length, erodibility and erosivity. Erosion was quantified, classified and mapped. The most comprehensive erosion class is the “strong” one. However, the “moderate to strong” to “very strong” classes account for 91.841%. Soil losses range from 6.933 ton/ha.year to 12173.283 ton/ha.year, with arithmetic mean of 1715.276 ton/ha.year and standard deviation equal to 792.560 ton/ha.year. Such results indicate a high tendency for soil loss, which may cause losses associated with incorrect planning of rural activities. The use of conservationist techniques, the correct anthropic occupation and maintenance of vegetation cover are extremely important measures for SRHS. |

Os procedimentos ocorreram no programa ArcGIS®, com auxílio de um banco de dados geográficos. Foi delimitada a BHCR com auxílio de Modelo Digital de Elevação. O potencial erosivo foi estimado através da Equação Universal de Perda dos Solos, com os parâmetros: decli- vidade, comprimento de rampa, erodibilidade e erosividade. A erosão foi quantificada, classifcada e mapeada. A classe de erosão mais abrangente é a “forte”. Porém, as classes “moderada a forte” a “muito forte” contabilizam 91,841%. As perdas de solo variam de 6,933 ton/ha.ano a 12173,283 ton/ha.ano, com média aritmética de 1715,276 ton/ ha.ano e desvio padrão igual a 792,560 ton/ha.ano. Tais resultados indicam alta tendência à perda de solos, podendo causar perdas associadas a um planejamento incorreto das atividades rurais. O emprego de técnicas conservacionistas, a correta ocupação antrópica e manutenção da cobertura vegetal são medidas de extrema relevância para a BHCR.Universidade Federal de Minas Gerais2022-09-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://periodicos.ufmg.br/index.php/ccaufmg/article/view/3715410.35699/2447-6218.2022.37154Agrarian Sciences Journal; Vol. 14 (2022); 1-6Caderno de Ciências Agrárias; v. 14 (2022); 1-62447-62181984-6738reponame:Caderno de Ciências Agrárias (Online)instname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGporhttps://periodicos.ufmg.br/index.php/ccaufmg/article/view/37154/31455https://periodicos.ufmg.br/index.php/ccaufmg/article/view/37154/31456Copyright (c) 2022 Caderno de Ciências Agráriashttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessFiorese, Caio Henrique UngaratoAguilar, Tiago Oliveira de2022-09-23T15:09:48Zoai:periodicos.ufmg.br:article/37154Revistahttps://periodicos.ufmg.br/index.php/ccaufmgPUBhttps://periodicos.ufmg.br/index.php/ccaufmg/oaiccaufmg@ica.ufmg.br2447-62181984-6738opendoar:2022-09-23T15:09:48Caderno de Ciências Agrárias (Online) - Universidade Federal de Minas Gerais (UFMG)false |
