Assessment of water management and hydropower potential of the river based on simulation modeling of water management balance

The article is devoted to the issues of substantiation of design solutions in the field of water management and hydraulic engineering construction using simulated water management models. The problems of creating databases using various models of natural processes, including climate forecasting systems and a model of atmospheric dynamics, are touched upon. The list of tasks that are solved with the use of MIKE class models, capable on the one hand to solve the problems of modeling natural processes, on the other – to carry out simulation modeling of natural technical systems, including water management, is considered. Software packages can be used to develop rules for managing individual reservoirs and their cascades. It is noted that when creating water management systems, determining their parameters and mode of operation, it is advisable to develop simulation models for expert water management analysis. This allows you to evaluate the functionality of the systems and avoid significant errors at more detailed stages of design and operation. As an example, the water management system of the Zapadny Manych, a tributary of the Don, is given. The problems of the object and the range of tasks to be investigated are formulated. The system functions due to the regular water supply of part of the Don and Kuban rivers flow to it. The transfer resources are spent on irrigation, hydropower and demineralization of Lake Manych Gudilo, which is a wetland of the Rostov region of international importance. In the work, the system is schematized and a hydrological and water management analysis of the development of irrigated lands and hydropower potential is carried out using simulation modeling of the water balance with optimization elements. The directions of further research on the water supply system of the Zapadny Manych River basin are formulated.
