Abstract: For the scientific substantiation of measures ensuring the rational use of water resources and the stable functioning of the Lower Volga water management system, a mathematical model, algorithm, and computational technology for the functioning of the Volga-Kama reservoirs networks (cascade) have been developed, which implements multi-criteria analysis methods for solving the problem of operational management of waterworks during the spring flood [1,2]. The methodology allows searching for trade-offs solutions in the interests of various water users (water supply, hydropower, transport, ecology, agriculture and fisheries, and others), based on a poorly defined hydrological forecast during the flood period (April-June). Computing technology was implemented for 9 large reservoirs (Figure 1): Rybinskoye, Gorkovskoye, Cheboksarskoye, Kuibyshevskoye, Saratovskoye and Volgogradskoye on the river Volga and Kamskoye, Votkinskoye and Nizhnekamskoye on the river Kama. The total useful volume of 9 reservoirs of the Volga-Kama cascade is 78.0 km3. The average annual inflow is 250 km3, during the spring floods (april-june) - 160 km3.
