Oszacowanie zasobów kompleksu wodonośnego za pomocą modelu numerycznego

Traditional methodology used for estimation of groundwater resources is based on hydrological methods. Application of numerical aquifer models enables to extend it with full water balance in the catchment. The balance makes possible the verification of coordination of various measurement data. This connected with calibration of hydrogeological parameters such as superficial replenishment or transmissivity of aquifer that can also be accomplished with numerical model. The utilizing of computer allows for taking into account of complex hydrogeological schemes as well as for easy calculation of local and regional dynamic and potential resources. Estimation of exploitational resources requires already the dynamical formulation including their relation with surface water resources. Aquifer model prrepared in such a way can become a foundation for simple linear models of groundwater drawdown impact on groundwater gaining stream. They can be utilized then in modeling of catchment water resources.
