Practice and Exploration of Integrated Operation of the Lower Jinsha River - Three Gorges Cascade Multifunctional Reservoirs

Abstract

The Lower Jinsha River - Three Gorges Cascade Multifunctional Reservoirs include 4 reservoirs: Xiluodu, Xiangjiaba, Three Gorges and Gezhouba, which have many functions such as flood control, power generation, navigation, ecology, water supply, and public safety. In order to give full play to the comprehensive benefits of the cascade reservoirs, the operation and management authority carries out integrated operation. In dry season, the power generation, navigation, ecology, and water supply needs are considered as a whole, and integrated drawdown operation are carried out. In flood season, take the needs of flood control, power generation, shipping and public safety into consideration, carrying out integrated flood prevention operation and connecting with water impoundment operation. This article summarized the practical experience of integrated operation of cascade multi-functional reservoirs, introduced the technical support system, and explored the development of a broader integrated operation of reservoirs.
