(Springer, 2016-11)In order to identify the origin of the main processes that affect the composition of groundwater in a karstic aquifer, a hydrogeochemical and isotopic study was carried out of water from numerous observation wells located ...
-
(ASCE-AMER SOC CIVIL ENGINEERS, 2008-04)This work presents a novel approach for solving groundwater management problems with reduced computational effort. We replace a groundwater flow model governed by a partial differential equation with a simple model governed ...
-
(Elsevier, 2020)In Central Chile, the increment of withdrawals together with drought conditions has exposed the poor understanding of the regional hydrogeological system. In this study, we addressed theWestern Andean Front hydrogeology ...

Groundwater resources of the Western Andean Front: insights from the Aconcagua Basin, Central Chile (Universidad de Chile, 2020)The misunderstanding of hydrogeological processes together with the oversimplification of aquifer conceptual models result in numerous inaccuracies in the management of groundwater resources. Despite that Chile is a ...
