The Experience in Applying a Water Reservoir Operation Model Using Dynamic Volume Nomograms in Exercising Special-Purpose Spring Water Releases

Resumo

Simulation models of river reservoir functioning in which dynamic volume nomograms are used to consider the non-horizontal nature of the reservoir water surface have not been so far applied due to the lack of accurate and fast-working computer realizations of such models. In 2015–2016, the authors of this paper developed such a program. In the periods of carrying out special-purpose spring water releases to the lower reaches of the Volga River in 2016 and in 2017, the developed model was used in a trial mode for a designing the reservoirs’ water regime. The results of water releases carried out under complicated hydrological and economic conditions proved the high performance of the model and confirmed the prospects of its application to solve the inverse problem.
