It is analyzed of the effect of the bed form change on the cross section flow measurement and calculation in the flume with the sand ripple bed or smooth bed. The reason is researched that the flow measurement error is caused by the river bed ripple. The Correction method is analyzed under the condition of different discharge and riverbed morphology. So the support is provided in order to improve the physical model discharge measurement accuracy. © (2013) Trans Tech Publications, Switzerland. Source

Zhenshui is the biggest tributary of Xiaolangdi Reservoir, and its original storage capacity is 1.767 billion m3 and accounts for 33.5% of the tributary. By October 2013, the amount of sediment in Zhenshui reached 0.2365 billion m3, and the sand bar was 5.78m in height. Influenced by operational mode of reservoir and terrain, the formation of sand bar at Zhenshui estuary has certain inevitabilities. The sand bar can prevent water and sediment exchange between mainstream and tributary, and the internal storage capacity of tributary is not effectively used. Analyzing sand bar and its cause can supply some technical supports for prevention. © (2014) Trans Tech Publications, Switzerland. Source

Sediment settling velocity is an important parameter in particle suspension and indispensable link of hyperconcentrated flow as well as basic theory support for efficient sediment transport of Xiaolangdi Reservoir. This paper has adopted current sediment sample in Xiaolangdi Reservoir to take still water settling experiment, observed carefully silt sediment distribution during different settling duration under various initial concentrations, analyzed common settling velocity calculation method, and adopted settling duration curve method as calculation method to obtain a constant settling velocity of free settling section. Typical settling velocity that is obtained from experiments makes supplement and fitness to settling velocity formula of the existing groups of sediment sample, amends the formula coefficient, further explore the settling characteristics and settling velocity of fine particle mixed viscous sediment with water concentration change, and meanwhile this paper researched settling distance impact on settling velocity, existing sediment group settling transition to mesh settling critical transition silt concentration of Xiaolangdi Reservoir. © (2014) Trans Tech Publications, Switzerland.

Turbidity current in reservoir is a specific phenomenon in nature, which could be used for sediment flushing to improve water resource utilization efficiency in reservoirs on sediment-laden rivers. For the conditions of muddy lake surface changing, this paper modifies the formula of turbidity current non-equilibrium sediment transport derived by Han Qiwei. This new formula was verified with the field data surveyed in the Xiaolangdi reservoir and showed an improved accuracy of calculation. Source

The simulation test on the late sediment storage period in shaping program of high floodland and deep-cut channel on the Xiaolangdi reservoir, and the evolution of high floodland and deep-cut channel, for the Xiaolangdi reservoir sediment retaining period reasonable reservoir operation mode, provide reference for reservoir extending service life.The study shows that:1Formation of High floodland and deep-cut channel evolution, which based on the beach sediment uplift and slot synchronization channel and then washed down the process, whether the erosion and scour quantity to whether can form high floodland and deep-cut channel topography is essential;2The tributary of the riverbed is equivalent to extending transversely, tributary river sedimentation process and topographic condition and tributary junction of the main river deposition pattern and process and other factors are closely related, tributary cross-sectional deposition morphology is mostly parallel to the raising tendency, department branch flow entrance there was a sandbar;3the reservoir during the flood period rainfall scouring camera, in favor of hyperconcentrated flow is generated, to a certain extent, recovery tank capacity, play long term use of reservoir. © (2012) Trans Tech Publications, Switzerland.
