Hydrodynamic characteristics and sustainable use of a karst aquifer of high environmental value in the Cabrejas range (Soria, Spain)

Abstract

This paper describes the research carried out in a karst aquifer located in Soria, Spain. The system presents considerable good-quality water resources, yielding a series of springs which constitute a “Natural Monument”. An integral study of the hydrological cycle is presented in order to characterize the hydrodynamic behavior of the aquifer. Research combines conventional geological and hydrogeological approaches with more innovative techniques such as speleo-diving. On the basis of relatively little available data, quantitative results are obtained. These include estimations on porosity, hydraulic conductivity, transmissivity, and groundwater renewal rate and aquifer reserves. A vulnerability assessment is carried out to evaluate the potential effects of overpumping. This is followed by a proposal for sustainable aquifer management. Since aquifers such as the one in this study are frequently found, this methodology could be successfully extrapolated to other cases.
