Resumo: This article presents the results of mapping the flow routes of surface runoff in an area characterized by profound changes in relief caused by anthropic interventions. We chose the Tucum stream upper basin (Sao Pedro, São Paulo - Brazil) as a case study because it is marked by the advance of urbanization on land with strong susceptibility to erosion, with the presence of linear erosive features (ravines and gullies) and a complex history of interventions seeking to control them. We obtained primary data from a topographic survey  in the field and carried out operations to develop a Hydrologically Consistent Digital Elevation Model (HCDEM) in the ArcGIS 10.1 program. Then, the Concentrated Flow Map of the area was elaborated from the modeling using the Multiple Flow algorithm in the ArcView 3.2 program. The results showed that topographic features of detail, especially technogenic terraces, have exercised marked control over the flow routes of surface runoff, contributing to generating erosive advance vectors of the ravines and gullies.

Como estudo de caso foi escolhida a alta bacia do córrego Tucum (São Pedro - SP), por apresentar um cenário marcado pelo avanço da urbanização sobre terrenos com forte suscetibilidade à erosão, com a presença de feições erosivas lineares (ravinas e voçorocas), e um complexo histórico de intervenções buscando o controle de tais processos. Foram utilizados dados primários, obtidos a partir de levantamento topográfico em campo, e executadas operações visando à elaboração de um Modelo Digital de Elevação Hidrologicamente Consistente (MDEHC), no programa ArcGIS 10.1. Em seguida, foi elaborada a Carta de Fluxo Concentrado da área, a partir da modelagem através do algoritmo Multiple Flow, no programa ArcView 3.2. Os resultados permitiram constatar que feições topográficas de detalhe, em especial, terraços tecnogênicos, têm exercido controle marcante sobre as rotas de fluxo do escoamento superficial, contribuindo para a geração de vetores de avanço erosivo das ravinas e voçorocas existentes na área.Universidade Federal de Uberlândia2020-11-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/4943110.14393/SN-v32-2020-49431Sociedade & Natureza; Vol. 32 (2020); 820-831Sociedade & Natureza; v. 32 (2020); 820-8311982-45130103-1570reponame:Sociedade & natureza (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUporenghttps://seer.ufu.br/index.php/sociedadenatureza/article/view/49431/30218https://seer.ufu.br/index.php/sociedadenatureza/article/view/49431/30219Copyright (c) 2020 Dener Toledo Mathias, Cenira Maria Lupinacci, João Osvaldo Rodrigues Nunesinfo:eu-repo/semantics/openAccessMathias, Dener ToledoLupinacci, Cenira Maria Nunes, João Osvaldo Rodrigues2021-07-01T16:18:20Zoai:ojs.www.seer.ufu.br:article/49431Revistahttp://www.sociedadenatureza.ig.ufu.br/PUBhttps://seer.ufu.br/index.php/sociedadenatureza/oai||sociedade.natureza.ufu@gmail.com|| lucianamelo@ufu.br1982-45130103-1570opendoar:2021-07-01T16:18:20Sociedade & natureza (Online) - Universidade Federal de Uberlândia (UFU)false
