Effect analysis of Yellow River improvement project from Wanglao Tan to Meijia Wan in Ningxia

对黄河宁夏段王老滩至梅家湾河段已建工程进行梳理,分别从工程治理前后河道平面形态、断面横向摆幅、弯道靠溜情况、河道流路变化以及工程对不同洪水的适应性等方面,对比分析河道整治工程治理效果.结果表明:该河段经微弯治理后,河道主叉及流路趋于稳定,工程布局基本合理,河势得到有效控制.建议今后应抓住有利时机,继续对工程段落进行上延下续.

To sort out the building project of Ningxia section from Wang Laotan to Mei Jiawan,by comparatively analyzed the treatment effect of the river training project in terms of flat from of the river, section transverse wing, turn by flow conditions, changes in the river channel, and project adaption to different floods and so on.It turned out that, after the micro-bend governance, the cross river and the main channel is becoming stabilized, the engineering layout is becoming reasonable, the river regime has been effectively controlled, it is recommended that, we should seize the favorable opportunity to continue extending this project section.
