RT Conference Proceedings T1 Hydrodynamic and hydrochemical evolution of the Bajo Guadalhorce Valley alluvial aquifer (Málaga, S Spain) in the last 40 years A1 Nieto-López, José Manuel A1 Barberá-Fornell, Juan Antonio A1 Andreo-Navarro, Bartolomé K1 Acuíferos K1 Hidrogeología AB Groundwater flowing through coastal aquifers is increasingly impacted by human pressures asconsequence of a growing demand on drinking water, tourism and agriculture, among others.Thus, groundwater availability very often depend on its quality since water salinization andpollution are the main challenges for water management because of seawater and freshwaterinteraction. Therefore, it is crucial to monitor the availability of groundwater and its quality underchanging scenarios where this water resource can be specially threatened.This study aims to assess the spatial distribution and time evolution of groundwater levels andhydrochemistry of the alluvial aquifer of the Bajo Guadalhorce Valley (Málaga, S Spain) for theevaluation of its quantitative and qualitative status. To that, groundwater level, electricalconductivity and Cl- and SO42- concentrations of water have been measured in a field samplingcampaign carried out in the alluvial aquifer of the Bajo Guadalhorce Valley (Málaga, S Spain) inApril 2017. Additionally, historical data from the last 40 years have been compiled.
