Land use and water quality in watersheds in the state of São Paulo, based on GIS and SWAT data

Land use influences the quality and availability of water resources, but Brazil has made little progress in integrated watershed management. This study therefore applied geoprocessing for land-use classification and evaluated the impact on the hydrological balance in order to contribute to the integ...

This study therefore applied geoprocessing for land-use classification and evaluated the impact on the hydrological balance in order to contribute to the integrated management of water resources. Using GIS tools, two drainage areas from the water catchment points of two municipalities, Santa Cruz das Palmeiras and Piedade, were delimited; land-use mapping was carried out using the supervised classification method of satellite images, and the SWAT model was applied for hydrological simulation. The methods used were appropriate. The surface runoff was related to the absence of vegetation and the predominance of exposed soil. The relationship between land use/land cover and the hydrological balance was evidenced, especially the impact of agricultural activities and the lack of natural vegetation in the surface runoff.Departamento de Saúde Ambiental Faculdade de Saúde Pública da Universidade de São Paulo (FSP/USP), Avenida Doutor Arnaldo, 715Instituto de Ciência e Tecnologia Departamento de Engenharia Ambiental Universidade Estadual Paulista “Júlio de Mesquita Filho” (UNESP), Avenida Três de Março, 511Instituto de Ciência e Tecnologia Departamento de Engenharia Ambiental Universidade Estadual Paulista “Júlio de Mesquita Filho” (UNESP), Avenida Três de Março, 511Universidade de São Paulo (USP)Universidade Estadual Paulista (Unesp)2020-12-12T00:56:15Z2020-12-12T00:56:15Z2019-01-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://dx.doi.org/10.4136/ambi-agua.2325Revista Ambiente e Agua, v. 14, n. 5, 2019.1980-993Xhttp://hdl.handle.net/11449/19800210.4136/ambi-agua.2325S1980-993X20190005003002-s2.0-85073300100S1980-993X2019000500300.pdfScopusreponame:Repositório Institucional da UNESPinstname:Universidade Estadual Paulista (UNESP)instacron:UNESPengRevista Ambiente e Aguainfo:eu-repo/semantics/openAccessVeiga, Denise Piccirillo Barbosa DaGuandique, Manuel Enrique Gamero [UNESP]Nardocci, Adelaide Cassia2025-11-15T05:07:32Zoai:repositorio.unesp.br:11449/198002Repositório InstitucionalPUBhttp://repositorio.unesp.br/oai/requestrepositoriounesp@unesp.bropendoar:29462025-11-15T05:07:32Repositório Institucional da UNESP - Universidade Estadual Paulista (UNESP)false
