Evaluation of hydrogeological conditions based on modelling: a case study in the Kampinos National Park region, central Poland

Hydrogeological modelling of the Kampinos National Park (KNP) region has been carried out. The KNP comprises a hydrogeological unit of valley relatively simple structure, and has been investigated empirically and theoretically since the 1970's. Results of numerical modelling given here provide a quantitative evaluation of hydrogeological parameters, recharging infiltration, river drainage and evapotranspiration processes (groundwater evaporation), water balance and the role of hydrodynamic zones in the recharge and drainage contribution in the water balance of the Vistula valley unit.
