Abstract (in english)
   Gravel pits near the Mohelnice city, Czech Republic, are situated in an aquifer that is important for ground water supply. The impact of gravel pits on ground water was assessed using numerical computer modeling; different stages of mining were simulated. The maximum rise of the ground water table has reached +1 m, while the decline is -3 m, compared to original levels. The gravel pits become drainage bases of the aquifer as the result of both mining activity and artificial changes in the Morava River channel. As a result of ground water flow into the open gravel pits, there is precipitation of calcite, pyrolusite and amorphous Fe(OH)3, as well as an increase of pH values.
