摘要
明渠是指人工渠道、天然河道以及非满管水流的管道,明渠水流具有共同的水力特征,即具有自由表面,且自由表面上的气体大气压,依靠重力能流动。明渠水流分为恒定流与非恒定流,明渠恒定流又分为明渠均匀流与明渠非均匀流。
Open channel is the artificial channel, natural and non-full pipe flow channel pipe, open channel flow have a common hydraulic characteristics, have a free surface, and the free surface of the gas pressure, to flow by gravity. Constant flow and open channel flow into unsteady flow; open channel flow is divided into a constant uniform open channel flow and non-uniform open channel flow.
