Abstract
In 1995, a hydrogeologie study was carried out in the Nere river catchment basin to assess the real hydraulic resources and the possibilities of harnessing the river for generating electricity. The following aspects were studied: 1) Assessment of available water resources and their temporal distribution 2) Identification of the main water souree 3) Calculation of exploitable water volumes 4) Possibility of increasing the water flow the spring surroundings Besides to the study of the meteorologieal, hydrologie and hydrogeochemical attributes, a geophysical prospecting survey was carried out by GPR with the aim of determining the geometrie boundaries in the spring zone and locating the impervious basement in a weir used as a gauging station.
