Calculation is the use of flood inflow of flood flow time curve to determine the maximum discharge for in order to determine the appropriate capacity and water level, from the data to calculate the four groups compared to the use constraints, and ultimately only the first option Meet the requirements. The weir crest elevation: 2810.2 m net width of the spillway crest: 7.2m.Design of Water Diversion Project is mainly on the intake section, the design of tunnel segments, according to the given information, select a pressure inlet, and using the known topographic and geologic conditions, including the intake pressure shaft, tower, tower bank, Dam-style, through analysis and comparison, the final choice silo intake, and intake of the inlet section of the elevation, the gate section, to determine the size of transition section to determine the tunnel hole diameter is 3.6m, tunnel length is 600m, not tunnel Hydraulic calculation, checking the design tunnel to meet the requirements, the lining of the tunnel structure calculation, the final result is both inside and outside with reinforced steel
