Stan zasolenia rzeki Odry za kolektorem »Olza« w zależności od jej przepływu i warunków atmosferycznych
(Wydawnictwa AGH, 2010) Swolkień, Justyna
This article treats about the state of salinity in Odra river in connection with its flow and atmospheric conditions. Very high chlorides concentration in the river is a consequence of dropping into its water highly contaminated mine waters form the south - western part of Upper Silesian Coal Basin. Mine waters are transported through the interceptor sewer called »Olza«. The author divides the river flows on the five categories and classifies them due to the exact water classes. Taking into consideration flow margins calculated by using the computer program called »Dyspozytor« and river absorptiveness due to the specific water class, it was possible to estimate the influence of dosing and retaining on the state of river waters salinity. It was also possible to state in which conditions there is a chance to keep the highest water class and in which there is no such a chance.

Wpływ zrzutów wód kopalnianych na wielkość przepływów wody w rzekach w początkowym okresie odwadniania odkrywki »Tomisławice« KWB »Konin«
(Wydawnictwa AGH, 2011) Wachowiak, Grzegorz
Since 2009, dewatering of the Tomisławice Open Pit has become yet another anthropogenic factor changing hydrographic conditions in the catchment of the Upper Noteć River above Gopło Lake. The flow values of watercourses receiving mine water, i.e. the Pichna and Noteć rivers, recorded in the period before mine dewatering have been analyzed. The values of mine water discharges provided by the Konin Brown Coal Mine are discussed and verified against the results of conducted hydrometric measurements. The verified values of mine water discharge were compared with characteristic values of river flow. The percentage of mine water discharge in the flow of the Pichna and Noteć rivers has been calculated. The necessity to include also other anthropogenic factors such as water discharge from the Warta-Gopło Canal to the Noteć River in the estimates of the impact of the Tomisławice Open Pit dewatering on river discharge and water resources of Gopło Lake is indicated. The paper is based, for the most part, on the results of water environment monitoring of the Tomisławice Open Pit carried out by the Institute of Meteorology and Water Management National Research Institute Poznań Branch in cooperation with the Poltegor-Projekt (Wrocław).
