Development of Hydrodynamic Model and the Model of Lowland Reservoir Pollution Formation (the Klyazma Reservoir as an Example)
Results of field observations of the heavy metals and their forms content in the Klyazma Reservoir bottom sediments, as well as oxygen and temperature in the water mass have been presented. Three groups of metals have been separated according the index of mobility in bottom sediments. The two-dimension hydrodynamic mathematical model and the model of pollution distribution have been developed. They enable to forecast formation of physical/chemical conditions in bottom layer that influence the water quality formation in terms of the heavy metals group. Within the reservoir two zones have been singled out: the transit zone and the stagnation (lake) zone; each of them are characterized by different proportion of metal forms in bottom sediments due to formation of oxide and anoxide zones in the bottom layer.
