    The objective of this thesis was presenting the changes in the salinity level of the Upper Vistula River before and after the implementation of the hydrotechnical protection system and reviewing the factors which may be affecting its effectiveness. The study of Cl- and SO42- levels was based on ion chromatography. After the systems implementation a decrease of salinity levels has been noted in every examined watercourse receiving the wastewaters disposed from the mine. In the monitoring point in Gostynia river a drop in salinity levels from 11,24g/dm3 to 8,58g/dm3 was observed. In the Vistula River at the Bieruń Nowy point the levels dropped from 3,93g/dm3 to 2,47g/dm3. In the monitoring point in Potok Goławiecki the levels dropped from 26,4g/dm3 to 15,35g/dm3 and in the Vistula River at Pustynia monitoring point from 2,83 g/dm3 to 0,95g/dm3. For retaining the normative levels of Cl- and SO42- there’s a need to relocate the control point Pustynia. Comparing the systems in the Odra and Vistula Rivers implies that the possibility of choosing the optimal versions of coal water dosages will come up no sooner then after the takeover of the retention-dosage functions by the excavations belonging to the inactive “Piast” Ruch II mine.

    The main purpose of this thesis was analysis of using the Vistula river cascade, which includes six weirs. Paper describes all of these weirs and their hydro-electric power plants. Furthermore it contains economic analysis of electric energy production based on hydro-electric power plants as well as ecological advantages of electric energy production in that way.
