ANALYSIS OF THE HYDROGEOLOGICAL CONDITIONS IN MODELLING OF GROUNDWATER RESOURCES IN THE BIAŁA PRZEMSZA AND PRZEMSZA CATCHMENTS

Abstract. The aim of hydrogeological modelling of the Przemsza and Biała Przemsza catchments was to estimate their disposable resources. The modelled area is more than 2000 square kilometres in size, and is about 680 square kilometres larger than the area of the catchments. This article focuses on the discussion on the applied model schematization, which takes into consideration mine drainage. The study area is characterised by a complicated hydrogeological system, additionally changed by human activity (mine drainage and water consumption for utility purposes). On a local scale, the hydrodynamic conditions should be regarded as transient. On a regional scale, with some approximation, they can be regarded as quasi-stationary. Complexity of the hydrogeological conditions prevents use of simple schematization involving the separation of a sequence of aquifers and aquitards. In this situation, it has been decided to develop a hydrogeological model consisting of seven layers, using lithological criteria
