The determination of the opening dimensions of an overflow dam includes the total width of the water discharge front, the elevation of the weir crest, as well as the number and size of the openings. In the design process, the water discharge method is first selected, along with an initial estimate of the weir crest elevation and the net width of the overflow dam section. Subsequently, based on factors such as the discharge volume, the allowable discharge per unit width, the type of gates, and operational requirements, hydrological calculations and flood control calculations for the reservoir are carried out to determine the characteristic flood levels and corresponding discharge volumes for each possible water discharge arrangement. A technical and economic comparison is then conducted to select the optimal solution.
The determination of the opening size design for an overflow dam includes the total width of the spillway front edge, the elevation of the weir crest, as well as the number and size of the openings. During design, the drainage method is usually determined first. Based on factors such as the discharge volume, the allowable discharge per unit width, the type of gates, and their operational requirements, flood control capacity and water levels for various drainage schemes are calculated through flood regulation calculations and hydraulic calculations. The discharge volumes corresponding to the designed flood levels are also determined, and a technical and economic comparison is carried out to select the optimal scheme.
