Hydrochemical characterization of groundwater in the Guadalquivir River aquifer in western Jaen: application of geostatistical techniques

摘要

The alluvial aquifer of the Alto Guadalquivir River is a shallow aquifer located in the central part of the province of Jaen, Spain, and its groundwater resources are used mainly for irrigation of crops in an important agriculture-dominated area (Lorite & Jimenez-Espinosa, 2008). This study is located in the western zone of this aquifer (Fig. 1). Hydrochemical and water quality data were obtained from April to June 2003, and 110 water samples were collected. The chemical composition of the water is not only influenced by the agricultural practices, but also by the interaction with the alluvial sediments.
