摘要
以川江小南海潜坝调节汊道分流量为例，说明坝高的设计采用水力学宽顶堰流量公式，比采用能量方程式推求水面线的方法计算要简单、快捷和准确．本文还介绍了川江小米滩用双潜坝分散消能的办法整治泡漩水。
t introduces that the design of dam height using the formula of broadcrest weir discharge is more simple,fast and correct than one using the method of water surface line calculation according to the energy equation.It also introduces that the method of dispersion consuming energy of twin submerged dikes is used to regulate the cell vortex flow and improve the navigation condition on Xiaomi shoal.
