In 2011–2013 complex experiments were conducted on the Uchinsk reservoir water area during different hydrological seasons. As a result of these researches a hydrodynamic model of Uchinsk reservoir has been developed on the basis of SMS v.10.1 (Surface-water Modeling System) licensed software package by AQUAVEO LLC in 2d approximation.The main factors influencing secondary pollution caused by bottom sediments, spreading of pollutants supplied from bottom sediments, as well as possibility to control the reservoir water quality have been highlighted. Quantitative hydro/physical, hydro/dynamic, and hydro/chemical criteria for forecasting of the probability of secondary pollution caused by the reservoir bottom sediments have been developed. A concept of reservoir zoning by the hazard level of water mass secondary pollution with heavy metals during the period of conditions favorable for heavy metals output from bottom sediments. On the basis of these criteria mapping of the Uchisk reservoir water area with the use of a mathematical model has been carried out. Measures on the reduction of the reservoir secondary pollution probability have been proposed.
