ABSTRACT

Using isotopic techniques to investigate hydrogeologic properties of aquifers and springs is a common approach nowadays that overcomes problems of monitoring classical hydrogeologic parameters such as piezometric levels and groundwater flow velocities. Nevertheless, interpretation of the results and maintenance of long term isotopic monitoring are also difficult and resource consuming tasks. In the present study the isotopic composition of springs and rain water has been examined in various sampling sites of Western Crete in order to identify spring-aquifer interactions and propose appropriate management and restoration measures. The output of this effort illustrated 4 main groups of springs sharing common isotopic characteristics and recharge zones. These potential recharge areas for each group have been delineated by combining the isotopic and geological properties of the entire area with the contribution of GIS techniques.
