Question

A horizontal bed channel is followed by a steep bed channel as shown in the figure. The gradually varied profiles over the horizontal and steep beds are

• A. $H_2$ and $S_1$ respectively
• B. $H_3$ and $S_1$ respectively
• C. $H_3$ and $S_2$ respectively
• D. $H_2$ and $S_2$ respectively

Answer 1

The correct option is D $H_2$ and $S_2$ respectively



When a flow profile changes from subcritical to supercritical flow, critical depth act as a control point.
