能告诉 manning's equation for SHEET FLOW (not for OPEN CHANEEL)吗？
翻了很多书也没找到：(
手边倒是有一个公式，但算出来显然不对(可能是单位的问题)。
谢了！！！

Manning's equation was developed based on the force balance of
a control volume in a open channel flow. the tricky part is the
selection of Manning's n value, which is determined by the
channel roughness, bed forms, vegetations and other factors.
So, I guess you are looking for Manning's n values for sheet flow
(> 300 feet) instead of the specific equation for sheet flow in
the similar form as V=1/n*R^(3/2)*S^0.5.
If you have other form of the Manning's equation, please share with
us. But I susp
