 abstract={Liquidation works carried out since 1994 in the post exploitation workings ofthe sulphurmine Machow are nearing completion. Its expected that by the end of the year 2000 the horizontal isolation layer forming the base of the future water reservoir will be completed. Dewatering ofthe mine however has to be continued at least until the partial filling of the reservoir by waters from the Wisła. At that time the pressure of the ore waters of the tertiary layer wi11 be in equilibrium within the recreational reservoir which won't cause the breakup (disintegration) of the newly formed isolation layer. In the end phase of its functioning the dewatering barrier system will undergo continual changes. These will occur as a result ofthe necessity ofmoving the internal we11 barrier from the base ofthe ore or the above-ore layer to the perimeter of the future water reservoir (external barriers). The quantity of withdrawn ore waters wi11 ensure the maintenance of the hydraulic height in the vicinity of the liquidated mine. The change in water relations was prognosed using a bydrogeological model ofthe Tarnobrzeg sulphur depression, this aBowed a piezometric estimation of the effectiveness of the ore dewatering system (Table 2) during consequent phases of the liquidation process. Each of these phases is also documented in the form ofhydroizohip maps (fig. 1--4) presenting the expected position of the hydrodynamic fields. These maps also show the increase in water table heights (impression) as compared to the state at the end of 1999 which is accepted as the initial state in simulation calculations. The obtained results from the prognostic calculations form the basis for the design or modification of barrier wells. During the filling up period of the reservior they will be helpful in a rational water management scheme.},
