Q5/The normal depth of flow in a rectangular channel (2 m deep and 5 m wide) is 1 m. It is laid to a slope of 1 m/km with a Manning's n = 0.02. Some distance downstream there is a hump of height 0.5 m on the stream bed. Determine the depth of flow (y1) immediately upstream of the hump.

Q5/The normal depth of flow in a rectangular channel (2 m deep and 5 m
wide) is 1 m. It is laid to a slope of 1 m/km with a Manning's n = 0.02.
Some distance downstream there is a hump of height 0.5 m on the stream
bed. Determine the depth of flow (y1) immediately upstream of the hump.
Answer: y1 = 1.27 m
