Hydrogeological compartmentation of the Guarani Aquifer System in the serra geral escarpment in the northeast of RS

The objective of this work was to evaluate the compartmentation of the Guarani Aquifer System (GAS) in the Serra Geral escarpment in the northeast of the RS. Therefore, the information of 276 tubular wells and the trace of morphostructural lineament at different scales were used, aiming to promote t...

Modelo Hidrogeológico.The objective of this work was to evaluate the compartmentation of the Guarani Aquifer System (GAS) in the Serra Geral escarpment in the northeast of the RS. Therefore, the information of 276 tubular wells and the trace of morphostructural lineament at different scales were used, aiming to promote the delimitation of hydrogeological compartments and to evaluate their influence on the aquifer characteristics. The results were used in the elaboration of a conceptual hydrogeological model. It was observed that the variations of the top of the GAS present relations with the relief of the region. The groundwater flow follows from the highest regions towards the limits of the compartments, following, in general, the top of the GAS, with characteristics of unconfined aquifer. The specific capacity presented a great variation between the compartments, with the most productive wells located near the discharge areas of the aquifer. Regarding the hydrochemistry, it was verified little differentiation between waters, with variations occurring mainly due to the influence of local characteristics. Thus, the results obtained in this study demonstrate that, in the study area, the GAS is compartmentalized, and that this compartmentation has influence both in productivity, as well as in the top of the SAG and in the groundwater flow.O objetivo deste trabalho foi avaliar a compartimentação do Sistema Aquífero Guarani (SAG), na Escarpa da Serra Geral no nordeste do RS. Para tanto, foram utilizadas informações de 276 poços tubulares e os traçados de lineamentos morfoestruturais em diferentes escalas, visando, com isso, promover a delimitação de compartimentos hidrogeológicos e avaliar a sua influência nas características do aquífero. Os resultados foram empregados na elaboração de um modelo hidrogeológico conceitual. Foi observado que as variações na cota do topo do SAG apresentam relações com o relevo da região. O fluxo de água subterrânea segue das regiões mais altas em direção aos limites dos compartimentos, acompanhando, em geral, o topo do SAG, com características de um aquífero livre. A capacidade específica apresentou uma grande variação entre os compartimentos, com os poços mais produtivos localizados próximo das áreas de descarga do aquífero. Com relação à hidroquímica, verificou-se pouca diferenciação entre as águas, com as variações ocorrendo principalmente por influência das características locais. Dessa forma, os resultados obtidos nesse estudo demonstram que nessa região o SAG se apresenta compartimentado, e que essa compartimentação tem influência tanto na produtividade, quanto na cota do topo do SAG e no fluxo da água subterrânea.ABAS - Associação Brasileira de Águas Subterrâneas2018-04-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://aguassubterraneas.abas.org/asubterraneas/article/view/2896510.14295/ras.v32i1.28965Águas Subterrâneas; v. 32 n. 1 (2018): REVISTA ÁGUAS SUBTERRÂNEAS; 130-1392179-97840101-7004reponame:Águas Subterrâneas (São Paulo.
