Abstract

This work analyzes the changes undergone by the coastal aquifer of Chipiona during the last half century, as a consequence of agricultural transformations and water management in the region. Initially, the aquifer suffered overexploitation and salinization due to marine intrusion in the 1990s and subsequently, an increase in storage as result of reduced pumping and increased recharge caused by the use of allochthonous surface water for irrigation. These modifications led to significant changes in groundwater hydrochemistry: (i) the salt wedge retreated notably and (ii) salinity increased owing to the agricultural soil washing and the application of irrigation water of poor quality from the lower basin of the Guadalete River. Finally, some management guidelines aimed at improving and protecting groundwater quality are proposed.
