Abstract:

The aim of the analysis was to compare physicochemical parameters and chemical composition of two groups of artificial reservoirs, mountain and lowland ones, characterised by different parameters and functions. Three mountain artificial reservoirs (Klimkówka, Dobczyce, Czorsztyn) located in the Upper Vistula basin (Carpathian Mountains in Poland) and three lowland reservoirs (Ivankovo, Verhnevolzhskoye, Vyshnevolotzkoye) located in the Upper Volga basin (Eastern European Lowland in Russia) were selected for the study. Data for the summer season in 2009-2013 were used in the analysis. Mountain reservoirs display high water concentrations of sulphates, chlorides and biogenic nitrates, and lower concentrations of ammonium and oxygen indicatorin relation to lowland reservoirs. Similar concentrations of phosphates were noticed in both the mountainand the lowland reservoirs. The hydrochemical differentiation between the individual mountain reservoirswas small, and statistically significant differences only occurred for SEC. Greater differentiation of the hydrochemical parameters was found among the lowland reservoirs. Statistically significant differences were demonstrated with regard to SEC, Cl- and NO3-.

Abstract:

The main objective of this paper was to demonstrate the changes in the natural thermal regime of the middle course of the Dunajec River, caused by the construction of the reservoir complex in the villages of Czorsztyn and Sromowce Wyżne 1994-1997. The analysis is based on water temperature measurements conducted in the river longitudinal profile, four times at the turn of 2012/2013 under hydrometeorological conditions for each season of the year. The field research results were expanded to include an analysis of archival materials relating to the temperature of the Dunajec River, in the hydrological years from 1984 to 2007, at the village of Krościenko’s water-gauging station. The station is located approximately 22 km downstream from the Czorsztyn and Sromowce Wyżne Reservoirs. The analysis showed that the formation of the Czorsztyn-Sromowce Wyżne Reservoir Complex caused a distinct change in the thermal regime of the mid-Dunajec River. Under favorable conditions these changes reach the Rożnów-Czchów Reservoir Complex.
