Many floodplains are excluded from development because the floods cause considerable damage to people’s lives and properties. Systems of hydraulic engineering structures for flood protection working with hydropower facilities are analysed to solve the problem of reducing the flood control volume of hydropower station. Methods of reducing the risk of flooding in the river basin by means of a distributed system of detention self-regulated dams are discussed. A geoinformation method used to justify the selection of parameters of such dams, primarily location of dam that minimize impact on the environment (ecological factor), is presented. In the present study, a system of multipurpose flood protection self-regulated dams is analysed as the measures for mitigation of flash floods in the Far Eastern region of Russia.
