Description:

Many factors affect the quality of water in rivers, including: types of pollution sources, the shape of the catchment, the type of land use, the amount of pollution flowing in. The construction of a retention reservoir is one of the factors affecting changes in the river valley related to the landscape, the environment, and water flow hydraulics. Reducing the velocity of water flow on the section of the reservoir causes changes in the characteristics of the movement of pollutants, some of them are deposited in the reservoir. The article analyzes water quality parameters at intake points located below (Uniejów) and above (Biskupice) of the Jeziorsko dam on the Warta River. The variability of such parameters as BOD5, TOC, pH, temperature, Ntot, Ptot was analyzed. The research also analyzed the dynamics of water inflow and outflow from the reservoir. The actual water retention time in the reservoir, which makes interpretation of the results difficult. The most indicators were characterized by the significance of differences for research in 2014.
