Question

From the Textbook: Problems: 1.1 (1 pt)-what slope would lead to a 1% difference between depth in the vertical plane rather than depth measured perpendicular to the channel bottom? Compare this slope to the observation that a channel slope of S. 0.01 m/m is generally considered quite steep for open channel flow.
