Abstrakt: Mathematical modelling is an efficient tool for evaluation of impacts of human activities and environmental changes on water quality in rivers and reservoirs. This contribution describes simulations of water quality in the Vltava River reservoir system, namely cascade of reservoirs Hněvkovice, Orlík, Kamýk, Slapy, Štěchovice, and Vrané. The two-dimensional water quality model CE-QUAL-W2 was used for this task over years 2000 to 2003. Sensitivity analysis, calibration, and evaluation of the model were done. The model gave good results in particular for hydrodynamics, water temperature, and conservative constituents because of good quality of available hydrological and meteorological input data. The accuracy of results was strongly depended on the quality of input data and sampling frequency. Minor problems occurred in water quality simulations based on monthly input data in periods with fluctuating discharges.
