Abstract: This study studies the historical and future evolution of the degraded quantity and quality of water resources in the coastal and agricultural Almyros Basin, in Greece. Multi-model ensembles of RCP4.5 and RCP8.5 projections from the Med-CORDEX database for precipitation and temperature have been corrected for bias and used in the analysis. The simulation of surface water and groundwater has been performed using an Integrated Modelling System that contains coupled models of surface hydrology (UTHBAL), groundwater hydrology (MODFLOW), nitrate leaching/crop growth (REPIC), nitrate pollution (MT3DMS) and seawater intrusion (SEAWAT). The results indicate that the water deficit will become larger, the nitrate pollution will be reduced, in general, although local prohibiting concentrations will be present, and the seawater intrusion will advance inland.
