Summary: In July 1991 started an applied hydrogeological research project in the electro-hydraulic analogy domain within large alluvial porous media saturated with groundwater of a common salinity. By using the resistivity sounding data, important geohydraulic parameters can be estimated accurately enough and considerably low-costly in comparison with conventional methods. The method of computation of necessary apparent geohydraulic parameters: the transmissivity index and the leakage index was researched and defined. The research results can be applied for: the selection of optimal locations and arrangements of pumping sites, the determination of pumping site sanitary protection zones, the estimate of alluvial aquifer recharge by the infiltration of precipitation and the estimate of groundwater vulnerability by agricultural pollution (fertilizers and pesticides). These results can be applied in almost all plains of large European rivers occurring within the zone of moderate climate. The international cooperation has obvious advantages. Several institutions from Germany, Hungary, Austria, Italy and, partly, from France responded affirmatively to the proposals for cooperation. A part of this research project ("Mapping of vertical permeability of loose sediments in large river plains by means of geophysical exploration") makes a contribution to an international research project having been organized by the Commission of the European Communities (COST Action 66 "Pesticides - Soil - Environment").

Keywords: Electro-hydraulic analogy, hydraulic conductivity index, transmissivity index, leakage index, alluvial aquifer, covering aquitard, large river plains, northern Croatia

Research goals: The basic goal of this applied hydrogeological research project is to determine a reliable relationship between two parameters, the hydraulic conductivity and specific electric** resistivity of loose clastics saturated with fresh groundwater and occurring in the large river plains of northern Croatia. After determining this relationship, two apparent geohydraulic parameters: the transmissivity index and the leakage index can be computed from the data obtained by shallow resistivity sounding. These indices control enough accurately the horizontal and vertical groundwater flows in large alluvial deposits. The parameter values obtained that way and plotted on maps may serve to solve several important water management problems in these river plains. They are: the discovery of high-yielding aquifers, the location of optimal pumping sites, aquifer modelling, the sanitary protection zoning of pumping sites, the estimate of precipitation infiltration magnitude and the groundwater vulnerability to agricultural pollution (fertilizers and pesticides). The research results can be applied not only in the plains of all large rivers in northern Croatia but also in almost all such river plains within the moderate climate zone. This research method is very fast, sufficiently accurate and, minimally, several times less-costly than the earlier applied methods. The aim is also to launch an international research cooperation within this project; either within the European Union cooperation in science and technology (COST Actions), or via bilateral scientific cooperation. By accomplishing it, (a) the number of research pilot areas would be increased, (b) the huge European scientific potential would be utilized and (c) the relationship hydraulic conductivity - electrical resistivity, the basis of this research project, would be more accurately determined.
