Gradually Varied Flow

When a supercritical stream enters a mild-sloped (M) channel section, the type of flow profile would become _________.

A rectangular channel with Gradually Varied Flow (GVF) has a changing bed slope. If the change is from a steeper slope to a steep slope, the resulting GVF profile is

Variation of water depth (y) in a gradually varied open channel flow is given by the first order differential equation $\frac{dy}{dx} = \frac{1 - e^{-\frac{10}{3}\ln(y)}}{250 - 45e...
