Opis:
The hydrochemical analyses of water inflowing, stored and flowing away from Mściwojów water reservoir were conducted from April to November 2012. Measured were 27 physico-chemical indices of surface water sampled at 8 dates from four measurement-control points. Analysis of results revealed that water inflowing into Kałużnik river was the best quality - corresponded to class III, but only due to nitrate nitrogen. In the water Wierzbiak from the river, only two from among 16 indices exceeded class II (nitrate nitrogen and phosphates). Water in the reservoir was classified to quality class III because of the temperature and BOD5 similar as water flowing away from the reservoir. Moreover, the paper assessed usable values of inflowing water, stored in the reservoir and flowing away from it. On the basis of the analysis, it was stated that water cannot be supplied to people since it does not meet the requirements stated in the Minister's regulations concerning the conditions of the natural habitat of cyprinids and salmonids.

Opis:
The paper presents the evaluation of soil water erosion risk of the Mściwojów water reservoir drainage basin. In the present study, modelling with the use of GIS (Geographical Information Systems) and RUSLE (Revised Universal Soil Loss Equation) erosion models were exploited. Values of topographic factor (LS) were calculated after formulas proposed by Moore et al. [1991] as well as Desmet and Govers [1996]. The results of erosion prognosis by means of RUSLE method after Moore's formula are by 40% higher than values evaluated after Desmet and Gover's formula. Eroded soil mean mass from area unit during the year is estimated at the level of 10.35-14.53 Mg • ha-1 • year-1, depending on computable formula used. Results of this research enabled to divide the drainage basin area into soil water erosion intensity zones based on predicted soil loss values according to Marks et al. [1989]. The study shows that water erosion risk of soil in the Mściwojów water reservoir drainage basin is very high. Almost one third of its area is located in the high and very high class of erosion risk.
