Abstract

In recent years, due to factors such as extreme climate and human activities, droughts have occurred frequently in middle and lower reaches of Yangtze River, causing certain adverse effects. In order to understand the runoff evolution law in middle and lower reaches of Yangtze River under dry conditions, and provide scientific reference for the water replenishment scheduling of the Three Gorges Project during dry water period. This study analyzed the measured data of various stations along middle and lower reaches of Yangtze River before and after the construction of the Three Gorges Project, to obtain changes in runoff propagation characteristics in various sections of the Yichang to Datong River section. Based on MIKE11, a hydraulic model of middle and lower reaches of Yangtze River was constructed, to study the dry water propagation characteristics of middle and lower reaches of Yangtze River under different scheduling methods of the Three Gorges. The research results have certain significance for the rational replenishment and scheduling of the Three Gorges Reservoir during dry water period, ensuring the production, living, and ecological water use in the middle and lower reaches, and further meeting the needs of navigation, irrigation, urban water supply, and resistance to salt tide invasion during the dry season.
