Abstract
After Tiaoxiankou was controlled by the sluice built in 1959, the deposition in front of the sluice has become very serious. The Hua rong River has lost its river function, and the water environment become worse and worse, so they all have affected the industry and agriculture production and resident life in this region severely. In the meantime, the Tiaoguan bend where Tiao Xiankou is located is excessively curved, the river regime is not smooth, the head of protrusive rocks of the Tiaoguan is very outward, releasing flood discharge is not effective, so the flood control situation is very severely and there is not good for the navigation. According to the problems of Tiaoxiankou and Tiaoguan bend, this paper puts forward two kinds of regulation schemes of cutting Tiaoguan bend in conjunction with double sluices control and cutting the head of protrusive rock of the Tiaoguan in conjunction with single sluice control. The two kinds of schemes have their own advantages and disadvantages and can reach the regulation target basically. The scheme implementation of cutting Tiaoguan bend in conjunction with double sluices control can fundamentally change the river regime conditions and flood control situation of Tiaoguan bend, and improve the navigation condition. However, existing facilities will be rebuilt, and some changes will be caused by river erosion and deposition of its upstream and downstream. The scheme implementation of cutting head of protrusive rocks of the Tiaoguan and single sluice control can basically solve the problem of head of protrusive rocks and some dangerous situations. Meanwhile, this scheme will not change the existing river regime. However, the over bent river bed and poor flood situation can also exist, and some part of Tiaoguan town need to be rebuilt. The two schemes can act as the basic schemes of regulation plan of Tiaoxiankou, Huarong River and Tiaoguan bend.
