Resumo: Groundwater has become an important source for water supply, due the increase of restriction for surface water supply, today with scarcity and poor quality conditions. This study aims to estimate the groundwater recharge of SASG and the surface water quality from two small watershed. The watersheds, with different land use, are located at northwest of Rio Grande do Sul State. The groundwater recharge was calculated base on the drain flow rate data, collected in dry conditions. To estimate the runoff time in each watershed it was calculated the concentration time. The flow rate on a dry period was considered as water withdraw from the aquifer. The monitoring program included physical and chemical data from surface water measured during a hydrological year. The land use was mapped base on Google Earth images. The recharge was estimated in 0,58252 m3/year/m2 in the watershed 1 and 0,95476 m3/year/m2 in the watershed 2. The watershed 2 has higher forest land use. According to the water use classification, indicated in the legislation, the surface water is classified as from Class 1.

Esse trabalho tem por objetivo estimar a recarga do SASG e caracterizar a qualidade da água superficial, em duas sub-bacias hidrográficas contíguas, em diferentes condições de uso e ocupação do solo na região noroeste do Estado do Rio Grande do Sul. A estimativa de recarga do aquífero foi realizada por meio de medições de vazão, sem a presença de precipitação, sendo calculada posteriormente ao tempo de concentração em ambas sub-bacias, após cada evento de precipitação. As estimativas e leituras dos parâmetros físico-químicos de qualidade da água foram realizadas durante um ano hidrológico. Para a obtenção das informações de uso e ocupação do solo foram utilizadas imagens do Google Earth. A recarga do aquífero foi de 0,58252 m3/ano/m2 na sub-bacia 1 e 0,95476 m3/ano/m2 na sub-bacia 2, sendo maior na sub-bacia 2. A sub-bacia 2 possui um percentual de vegetação superior que a sub-bacia 1, propiciando melhores condições para a infiltração da água oriunda da precipitação. Os parâmetros físico-químicos caracterizaram as águas correntes de ambas sub-bacias como de Classe 1, de acordo com a legislação vigente.Universidade Federal do Rio de Janeiro2016-10-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufrj.br/index.php/aigeo/article/view/701010.11137/2016_3_25_31Anuário do Instituto de Geociências; Vol 39, No 3 (2016); 25-31Anuário do Instituto de Geociências; Vol 39, No 3 (2016); 25-311982-39080101-9759reponame:Anuário do Instituto de Geociências (Online)instname:Universidade Federal do Rio de Janeiro (UFRJ)instacron:UFRJporhttps://revistas.ufrj.br/index.php/aigeo/article/view/7010/5577Copyright (c) 2016 Anuário do Instituto de Geociênciashttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessGraepin, CristianeMancuso, Malva AndreaCamargo, MarizaSilva, José Luiz Silvério daBorba, Willian Fernando de2017-02-15T18:21:53Zoai:www.revistas.ufrj.br:article/7010Revistahttps://revistas.ufrj.br/index.php/aigeo/indexPUBhttps://revistas.ufrj.br/index.php/aigeo/oaianuario@igeo.ufrj.br||1982-39080101-9759opendoar:2017-02-15T18:21:53Anuário do Instituto de Geociências (Online) - Universidade Federal do Rio de Janeiro (UFRJ)false
