 abstract={The Belchatów lignite open pit dewatering caused changes in water management of the area. Groundwater natural resources were changed. While groundwater storage were reduced, groundwater renewable resources were grown. For estimation the changes of ground water resources, ground water flow model was constructed representing the study area of about 2500 km2. The model simulation was performed for steady state condition for the period before drainage system has been put into operation and also for transient conditions as a result of 20-years mine dewatering with the mine water inflow ranged from 170--450 m3/min. The results obtained during simulation indicate that in the range of dewatering influence area effective infiltration from precipitation grows about 50%. Additional recharge of aquifer as a result of increase of water infiltration from water courses as well as artificial recharge from disposal site caused that the total renewable resources increased about 80%. After 20-years of dewatering, the total mine water inflow from groundwater renewable resources was 72. 7% and from groundwater storage was 27.3%.},
