Abstract

Today the flood capacities of the Moscow water reservoir system are determined depending on catastrophic spring floods. The rain flood volumes and the consequent maximum discharges are much less of spring flood volumes and the consequent maximum discharges. Main hypothesis of the research is possibility of safe use of flood capacity and drafts from water reservoir after the end of spring flood recession. Accordingly the aim of the research is safe use of flood capacity part for the water storage during summer after spring floods. The aim has required of solving of next problems: - to model the spring and rain flood hydrographs respecting of different probability; - to develop the new logical conditions for flow control by water reservoir; - to research different scenarios of river flow and reservoir operation respecting of the possible drafts from flood capacity; - to check the developed new rules with help of simulation of water reservoir operation; The modeling of the spring and rain flood hydrographs respecting of different probability was made on the base of long time observations according to Russian normative methods. It have been established that there is possibility of the increasing water level upper Normal Water Reservoir Level after main wave of spring flood for the added drafts from flood capacity and for the increasing of water exchange in water reservoir and river system. The added drafts from flood capacity and increased of water exchange in water reservoir and river system during June month allows decrease of blossom blue-green algae and improve the quality of water resources. A probability of alarm situation respecting of big water levels during spring and rain floods is not increased.
