摘要
Abstract
The Jianli reach is one of the obstructive waterways in the Yangtze River and becomes worse since the commissioning of the Three Gorges Project. The paper constructs a plane 2-D water and sediment mathematical model for the Jianli reach and the evolution process of the Jianli reach is simulated. Experimental data are used to verify the model. The results show that the river regime will not change greatly under natural conditions, and the Wuguijia reach will exist perennially as the main channel, especially after the commissiong of the Three Gorges Project. Along with the operation of the Three Gorges Project, the head of Wugui island will be eroded continuously, and the shoal will not change much, which is still the main navigation obstruction. Finally, some river regulation methods are proposed in the paper.关键词
