【Objective】 Weir is a classical apparatus measuring water flow rate in open channels. Its accuracy and the formula used to calculate flow rate depend on many factors. In this paper, we proposed a new method to calculate flow rate with measurement

In restricted topographic conditions,a falling-sill can be set at the end of the discharge chute for the spillway.The length of the dissipation pool is shortened by increasing the flow velocity attenuation along the way of the jet,or increasing the s

When the topography conditions cannot satisfy the needs of the length of the stilling pool during traditional bottom-flow energy dissipation,the energy can be dissipated by increasing the depth and width of the pool.To obtain suitable depths for a re
