【Abstract】 A mathematical model and analysis is applied to simulate the channel regulation engineering measures of Jiepai reaches in the transition segment. The model has been finished according to the water-sediment characteristics of Jiepai reaches on the Middle Yangtze River. The research achievements be submitted including erosion and deposition volume, navigation channel change, velocity distribution, current regime in calculation stretch after channel regulation, are useful to design.更多还原
