Abstract: The aim of this paper is to review the water resources of the Korisos basin located in the NW Greece and to explore the ground- and surface water interactions. Based on results, it can be concluded that there is a hydraulic communication between the torrent flow and the alluvial aquifer, indicating the important role of stream flow to recharge the alluvial aquifer. Total abstraction from the aquifer appears to be sustainable as deduced from groundwater level measurements. Furthermore, it is pointed out that the exploitation of surface water and groundwater simultaneously would allow a maximisation of water use efficiency.
