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.

Zastosowanie programu komputerowego »Dyspozytor« jako narzędzia w procesie regulacji rozpływu wody w kolektorze »Olza«
(Wydawnictwa AGH, 2010) Swolkień, Justyna
The article treats about the usage of »Dyspozytor« application in mine waters' flow regulation inside the »Olza's« interceptor sewer. Lack of its regulation is a main reason for huge variations of chlorides and sulphates concentration in the Odra river what in the end drives its ecosystem to the total destruction. Computer calculations show that in order to remain stable chlorides and sulphates concentration it is necessary for each interceptor sewer's object to work with a proper working parameters'. The computer program, together with »Olza's« interceptor sewer, helps to regulate water flow from each mine. It determines what kind of water class is possible to obtain taking into consideration river flow and its earlier contamination. Thanks to it is possible to maintain constant chlorides and sulphates concentration due to the exact water class. It is also possible to maintain low pressure in the interceptor sewer's pipelines what improves its energy consumption.
