Problem oceny zasobów odnawialnych wód podziemnych systemów wielowarstwowych metodą modelowania na przykładzie zlewni Kłodnicy

Groundwater renewable resources are the basis to estimate water-bearing and safe exploitation. Safe yield (disposal resources) in turn, exerts the influence on decisions about new intakes location, limitation of groundwater extraction in the older one and limitation of land use by defining protection areas. In spite of this, the problem seems to disappear in polish scientific literature and documentations. From numerous consultations in revisers circle during execution of groundwater model of Klodnica catchment, results that there is possible various approach to renewable groundwater resources assessment. The conclusion is that the discussion is needed about the methodology and feasibility of such estimations in some cases. Groundwater renewable resources are still important point of most of the resources documentations. In this paper, the problem of distinguishing of resources in sub element of the system was shown. There was performed analysis of different possible solutions . The varies advantages and hazards was taken into consideration and the final solution was proposed.
