Resumo: The natural water erosion process occurs at a slow rate and the anthropic impact changes these equilibrium conditions, intensifying the process. Among the characteristics that condition this process, the susceptibility to laminar and linear erosion at the edges of Itumbiara Hydroelectric plant reservoir (GO/MG) is outstanding. In this regard, the general objective of the research is to present a proposal for modeling the susceptibility and laminar and linear water-erosion potential, at the edge of reservoirs. In order to achieve this objective, in addition to the registration of the respective land features, processing of digital elevation models and the mapping of physical conditions were carried out. The observed erosive processes coincided, in general, with moderately high or medium susceptibility classes. As for potentiality analysis, there is predominance of agropastoral use over high or moderately high susceptibility, both for the laminar and linear erosions.

Dentre as características que condicionam esse processo, destaca-se a suscetibilidade à erosão laminar e à linear nas bordas do reservatório da UHE de Itumbiara (GO/MG). Neste sentido, o objetivo geral da pesquisa é apresentar uma proposta de modelagem da suscetibilidade e da potencialidade erosiva hídrica, laminar e linear, em borda de reservatórios. Para atingir tal objetivo, além do cadastro das respectivas feições, foi realizado o processamento digital de modelos digitais de elevação e o mapeamento dos condicionantes físicos. Concluiu-se que, em geral, os processos erosivos coincidem com as classes moderadamente altas ou de média suscetibilidade. Quanto à potencialidade, ocorre o predomínio do uso agropastoril sobre alta ou moderadamente alta suscetibilidade, tanto para o processo erosivo laminar quanto para o linear.EDUFU - Editora da Universidade Federal de Uberlândia2022-10-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado pelos paresapplication/pdfhttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/5990610.14393/RCG238959906Caminhos de Geografia; Vol. 23 No. 89 (2022): Outubro; 34-56Caminhos de Geografia; Vol. 23 Núm. 89 (2022): Outubro; 34-56Caminhos de Geografia; v. 23 n. 89 (2022): Outubro; 34-561678-6343reponame:Caminhos de Geografiainstname:Universidade Federal de Uberlândia (UFU)instacron:UFUporhttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/59906/34757Copyright (c) 2022 Diego Tarley Ferreira Nascimento, Patrícia de Araújo Romão, Maurício Martines Sales, Marta Pereira da Luzhttp://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessRomão, Patrícia de AraújoNascimento, Diego Tarley FerreiraSales, Maurício Martines da Luz, Marta Pereira2022-10-11T13:56:10Zoai:ojs.www.seer.ufu.br:article/59906Revistahttps://seer.ufu.br/index.php/caminhosdegeografia/indexPUBhttp://www.seer.ufu.br/index.php/caminhosdegeografia/oaiflaviasantosgeo@gmail.com1678-63431678-6343opendoar:2022-10-11T13:56:10Caminhos de Geografia - Universidade Federal de Uberlândia (UFU)false
