Question

for a hydraulically efficient rectangular channel of bed width 4m, depth of flow is​

Answer 1

Normal depth is the depth of flow in a channel or culvert when the slope of the water surface and channel bottom is the same and the water depth remains constant. Normal depth occurs when gravitational force of the water is equal to the friction drag along the culvert and there is no acceleration of flow
