梯形渠道的水力最优断面因为具有在过水断面面积一定时通过的流量最大的特点,是水利工程中一种常见的渠槽形式,它的断面设计需求解一个很复杂的高次方程。
Trapezoid channel is a common form in hydrological project with characteristic of maximum influx at a certain time, its section designing requires a complex equation of higher degree.
泄洪道,分洪道,溢流槽天然或人造的泄洪渠或泄洪管道,以引导洪水绕过或远离城市中心或人口稠密地区。
Floodway; high-flow diversion Natural or man-made bypass channels or conduits that redirect flood waters around or away from urban centers or area of high population density.
出泄槽水流挑流消能后在渠道内加速,使出渠流速仍然较高。
The water flow in the canal speeds up after energy dissipation in the discharge flume, so the velocity of flow is still high in the canal.
