摘要：Salinity is a common problem in Greek islands, especially, during the summer period when the saltwater intrusion becomes more severe due to extensive over pumping. In the past few years, the industrial zone of the City of Herakleio in Crete appears to have an increasing water demand as result of the continuous industrial development. The water demand is mainly cover from groundwater resources. The karstic nature of the geological formations beneath the industrial zone has a great impact in the overall hydro-geological characterization of the aquifer. Also the expansion of the saltwater front into the aquifer is hard to be determined due to the presence of innumerable cracks, which act as closed conduits of saltwater and the density variation between the saltwater and the fresh water. The main objectives of this study were to map the geology and the salinity zone in the area based on geophysical measurements. The industrial zone lies on a karstified limestone with several faults that need to be delineated. Mapping of the area revealed also specific places that were recommended for observation wells. In the future, these wells are planned to be used as injection wells for the restoration of the aquifer. Another objective of this study was to propose different management scenarios to inhibit the saltwater intrusion front further inland. In this paper, scenarios that suggest artificial recharge of fresh water are presented in order to raise the groundwater level and to create a groundwater flow towards the sea.
