On the reseaech project "Identification of the hydraulic parameters of covering aquitards in the northern Croatian plains"

This paper refers to a kind of continuation of an earlier, just terminated national (Croatian) research project but it is also a part of just launched international (Danubian) and multidisciplinary research programme. The presented part of the research belongs to a segment of the bilateral German-Croatian cooperation in the field of scientific research. The basic hydraulic parameters of covering aquitards will be tried to be determined on the basis of pumping tests of several selected individual wells. These parameters will also be determined on four pumping sites where groundwater have been pumped for a long time and where water pressure changes were observed in neighbouring observation wells. The values of the hydraulic parameters of covering aquitards obtained this way will be used to determine - otherwise, till now not yet accurate - relationship between geohydrautic and geoelectric parameters and, by doing this, to enable the use of a simple and retatively inexpensive applied-hydrogeological method for the evaluation of aquifer recharge conditions and, especiaily, its vulnerability to the pollution from ground surface.
