Estimation of recharge of the Guarani Aquifer system based on the application of the water-table fluctuation method in the Ibicui River-RS

The estimation of groundwater recharge is determinant for the sustainable groundwater management. The recharge can be estimated using different methods according to the characteristics of the studied area, the spatial and temporal scales and data availability. The goal is to estimate the recharge of...

Unconfined aquifers. WTF. Ibicuí basin.Recarga subterrânea. Aquíferos livres.VNA. Bacia do Ibicuí.The estimation of groundwater recharge is determinant for the sustainable groundwater management. The recharge can be estimated using different methods according to the characteristics of the studied area, the spatial and temporal scales and data availability. The goal is to estimate the recharge of unconfined aquifer units that belong to the Guarani Aquifer System, located in the Ibicuí River basin, based on the application of the Water-Table Fluctuation (WTF) method. The water level data were obtained from five monitoring wells of the RIMAS project operated by the CPRM/Brazilian Geological Service. The method was applied to the monthly average of the water level to each monitoring well, in periods between 24 and 39 months. The monthly recharge estimations were about 417,0 mm to 730,7 mm, and the values of precipitation that correspond to recharge varied between 11% and 18%, with an average of 13,82%. It was observed that the highest values occurred in the northwest region of the basin, while the lowest were found in the southern region. The method delivered good results when compared to other assessments that were carried out in the same region.A estimativa da recarga subterrânea é determinante para a gestão sustentável das águas subterrâneas. A recarga pode ser estimada usando diferentes métodos que variam de acordo com as características da área estudada, as escalas temporais e espaciais adotadas e a disponibilidade de dados. O objetivo é estimar a recarga de unidades hidroestratigráficas pertencentes ao Sistema Aquífero Guarani (SAG), localizado na bacia do rio Ibicuí, com base na aplicação do método Variação dos Níveis d'Água (VNA). Os dados de nível d'água foram obtidos a partir de cinco poços de monitoramento pertencentes à rede RIMAS (Rede Integrada de Monitoramento de Águas Subterrâneas) da CPRM/Serviço Geológico do Brasil, instalados na bacia. O método foi aplicado para a média mensal dos níveis de água em cada poço de monitoramento, em períodos que variaram entre 24 e 39 meses. A recarga mensal foi estimada entre 417 mm e 730,7 mm, e as porcentagens de recarga em relação à precipitação variaram entre 11% e 18%, com média de 13,82%. Na região noroeste da bacia foram encontrados valores mais altos em contraposição à região sul. O método apresentou resultados compatíveis com outros estudos realizados na mesma região.ABAS - Associação Brasileira de Águas Subterrâneas2017-03-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://aguassubterraneas.abas.org/asubterraneas/article/view/2863110.14295/ras.v31i2.28631Águas Subterrâneas; v. 31 n. 2 (2017): REVISTA ÁGUAS SUBTERRÂNEAS; 12-292179-97840101-7004reponame:Águas Subterrâneas (São Paulo.
