ABSTRACT: Turów, a lignite opencast mine in Poland, has strongly influenced the hydrogeological condition of the Tertiary Žitava basin in the Czech Republic. The excessive pumping caused watertable drops of up to 60 m in the Czech part of the Žitava. The four-layered flow model proved that the spreading of groundwater depression is undergoing mainly within the Middle Tertiary aquifer into the Czech part of the Žitava basin. All aquifers are separated by an east-west fault on the border of Poland and the Czech Republic. The east-west fault behaves as a hydraulic barrier, except for the Middle Tertiary aquifer. The Upper Tertiary aquifer is significantly affected by direct pumping in Turów mine in the Polish area and leakage to the Middle Tertiary aquifer in the Czech area. Groundwater drops in the Tertiary aquifers lead to a decline in water levels of the Quaternary aquifers and the water losses in the brooks.
