sediment discharge
2.It has conducted physical model tests on five plans of different operational modes of Sanmenxia Reservoir and different combination of sediment discharge conditions and analyzes the influence of different sediment discharge conditions and different operational modes to scour and fill of reservoir area.
5.Complicated hydrologic and geographic conditions,and the large scale of the Xiaolangdi Hydraulic Project on the Yellow River are introduced briefly.Three desilting tunnels are designed to meet the requirements of flood control,sediment discharge and runoff regulation.According to the performance requirements of desilting tunnels,the tunnel lining down-stream of the grouting curtain is designed to be post-tensional prestressed lining.On the basis of investigation and research,experiements and analysis,the unbonded prestressing system is used.It is the largest unbonded prestressed tunnel lining project in the world,and the first one in China.
6.The paper managers to explore the feasibility of automatic monitoring technology for flow discharge in Yellow River Flow Diversion Channels. This technology integrates high accurate water gate position control and high accurate water level gauge in heavy sediment and discharge calculation model with 485 computer communication to approach automatic discharge monitoring in water diversion project for optimizing regulation in water resources development.
9.The variation range of temperature was between 24.9℃ and 30.1℃ and the range of salinity was between 4.1 and 33.7,with higher temperature and lower salinity toward the mouth of Minjiang. The observations show that the sediment content on the ebb is higher than that on the flood in both HuJiang and YunDou channels,meaning that the river discharge plays a significant role in sediment transportation.
