A wide rectangular channel has a change of slope from 1 in 100 to 1 in 500 and the flow is 4m3/s/m. Manning's n can be taken as 0.015
a. Determine the normal depth of flow before and after the change in gradient. Will it be possible to produce a hydraulic jump in the channel downstream of the junction of two slopes?
b. Calculate the height of the jump and sketch the surface profiles before and after jump.
c. Calculate energy loss and approximate dimension of the jump.
