Investigating the Effects of Agricultural Water Management in a Mediterranean Coastal Aquifer under Current and Projected Climate Conditions

Coastal delta plains are areas with high agricultural potential for the Mediterranean region because of their soil fertility, but they also constitute fragile systems in terms water resources management interaction underlying aquifers sea. Such a case is Pinios River plain located central Greece, which constitutes significant ecosystem. Soil and Water Assessment Tool (SWAT) SEAWAT models were combined order to simulate impact current practices main groundwater budget components salinization shallow aquifer developed area. Moreover, climate change was investigated using data from Regional Climate Model two projected periods (2021–2050 2071–2100) sea level rise scenarios (increase by 0.5 1 m). Modeling results providing insight: although contribution river inflows significant, direct recharge precipitation found be higher, while capillary major part outflows aquifer. during simulation period, flow higher than seawater Regarding assessment, indicate that variability posed increasing aquifer’s deterioration both its quantity quality status, latter expressed increased Cl? concentration. This evidence becomes more limited storage capacity Concerning rise, it less compared decrease increase crop needs.
