For a given channel geometry slope and roughness and a specified value of discharge a unique value of depth occurs in steadyuniformflow.
对于给定的河道几何形状、坡度、粗糙度以及规定排水量,均匀稳流中出现唯一深度值。

Most of wter flow in open-channel or in river belongs to steady non-uniformflow. The surface profiles are caused by changes of channel section. It is very important to analyze its computations.
