Resumo: | This article presents the results of a research aimed at geotechnically and geoenvironmentally characterizing the São Pedro stream basin, located in Uberlândia/MG - Brazil, from the physical environment’s attributes and properties, with a view to using land as a means of rainfall infiltration. The used methodology focuses on analytical mapping and generating cartographic documents that are individually elaborated and analyzed. Besides that, the characterization of unconsolidated materials (in situ and in laboratory) and coefficient of permeability (k) tests (in situ with a Guelph permeameter) were performed. With this data at hands, a quali-quantitative analysis of the physical environment’s features was made through the study of its attributes and their representation in maps. Variables related to infiltration and runoff processes were privileged. For the area of the São Pedro stream basin, values of k varying between 10-4 and 10-5 cm/s were found. The adequacy-to-infiltration map showed the areas next to the streams and in the stream’s mouth as non-adequate or slightly-adequate. On the other hand, the areas close to the drainage divides of the basin showed to be highly-adequate. The center of the basin and the region between the Jataí and the Lagoinha streams are also highly-adequate to infiltration. These areas with higher adequacy are appropriate to the implementation of structural and non-structural measures that seek to reduce flood risks. Thus, we hope to contribute to urban planning in this study area through these geoenvironmental maps. |

A metodologia utilizada concentra-se no mapeamento analítico, gerando documentos cartográficos elaborados e analisados individualmente. Além disso, é feita a caracterização de materiais inconsolidados (in situ e laboratório) e ensaios do coeficiente de permeabilidade (k) (in situ com o permeâmetro Guelph). De posse de todos os dados foi feita a análise quali-quantitativa das características do meio físico pelo estudo de seus atributos e sua representação em mapas, privilegiando variáveis relacionadas à avaliação de processos de infiltração e escoamento. Para a área da bacia do córrego São Pedro foram obtidos valores de k variando entre as ordens de grandeza de 10-4 a 10-5 cm/s. O mapa de adequabilidade à infiltração apresentou ser não adequado ou pouco adequado nas áreas mais próximas aos canais e na foz do córrego principal. Os terrenos situados próximos aos divisores de água da bacia apresentam-se muito adequados. O centro da bacia e a região localizada entre os córregos Jataí e Lagoinha são também muito adequadas à infiltração. Estas áreas com maior adequabilidade são apropriadas à implantação de medidas estruturais e não estruturais, visando reduzir riscos a inundações. Assim, de posse destes mapas geoambientais espera-se contribuir para o planejamento urbano na área de estudo.Universidade Federal de Uberlândia2019-10-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/4634410.14393/SN-v31-2019-46344Sociedade & Natureza; Vol. 31 (2019)Sociedade & Natureza; v. 31 (2019)1982-45130103-1570reponame:Sociedade & natureza (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUporenghttps://seer.ufu.br/index.php/sociedadenatureza/article/view/46344/27256https://seer.ufu.br/index.php/sociedadenatureza/article/view/46344/27257Copyright (c) 2019 Ana Clara Mendes Caixeta, Vanderlei de Oliveira Ferreira, Luiz Nishiyamainfo:eu-repo/semantics/openAccessCaixeta, Ana Clara MendesFerreira, Vanderlei de OliveiraNishiyama, Luiz2019-11-07T10:49:13Zoai:ojs.www.seer.ufu.br:article/46344Revistahttp://www.sociedadenatureza.ig.ufu.br/PUBhttps://seer.ufu.br/index.php/sociedadenatureza/oai||sociedade.natureza.ufu@gmail.com|| lucianamelo@ufu.br1982-45130103-1570opendoar:2019-11-07T10:49:13Sociedade & natureza (Online) - Universidade Federal de Uberlândia (UFU)false |
