In order to prevent floods on rivers in the presence of a cascade of hydroelectric power plants, it is possible to use the methods of railway transport in the management of their operation, which ensure the prevention of prolonged congestion in the movement of trains due to the accumulation of an increased fleet of wagons on certain landfills. In railway transport, the most dangerous in operational activities are unloading points located mainly on the outskirts of the country or the continent of Eurasia. For railway transport, the most important point in management is the reception of trains during the overhaul of tracks on main lines, mainly located in the central geographic center of the country, located in Kuzbass in Russia. On rivers, in the event of electricity generation, the most dangerous place is the hydroelectric power station located in the middle of an extended river basin. However, the most important and effective points in managing their operation are the upper and lower hydroelectric power plants. The lower hydroelectric power plants provide a quick discharge of excess water, which helps prevent floods. Upper hydroelectric power plants allow one to raise the water level of the cascade of the entire extended river basin at a lower cost.
