Varni Ciencias de la Tierra water groundwater recharge table fluctuation method groundwater flow modeling chloride mass balance method This work used several methodologies to evaluate the vertical groundwater recharge from precipitation in the Azul aquifer, central Buenos Aires province, Argentina. Firstly, the spatial variation of the recharge was evaluated and then the temporal variation in the recharge was analyzed in a station located in the center region of the study area. Several independent methods were applied to evaluate recharge: chloride mass balance method, water-table fluctuation method, and groundwater flow modeling in steady-state and in transient conditions. The results obtained show that the temporal variation in the recharge (measured in annual periods) was considerably greater than the variability in the precipitation that generated it, for all the applied methods and all the analyzed periods. The annual mean groundwater recharge varied from over 20% of the annual mean precipitation in the upper basin to less than 10% of the precipitation in the plains (lower basin), with intermediate values in the middle sub basin. A conceptual model of the groundwater system is proposed and its relationship to the recharges in each sector of the basin. This model identifies a regional flow system and local systems of different sizes. 2013 artículo científico 2007-2422 https://www.redalyc.org/articulo.oa?id=353531983007 es http://www.redalyc.org/revista.oa?id=3535 Tecnología y Ciencias del Agua application/pdf Instituto Mexicano de Tecnología del Agua Tecnología y Ciencias del Agua (México) Num.3 Vol.IV |
