List of top Water Resources Engineering Questions on Channel Hydraulics

Width (in m) of a rectangular channel required to carry a discharge of 96 m3/s at a critical depth of 9.8 m is (rounded off to two decimal places).

Use acceleration due to gravity = 9.8 m/s2
The flow depth for a discharge of 10 m3/s in a wide rectangular channel is 2.0 m. Assume that the flow is uniform.

If the discharge is doubled, the flow depth (in m) in this channel is (rounded off to two decimal places).
A wide unlined channel carries sediment-free water. The depth of water is 1 m. The specific weight of water is 10 kN/m\(^3\). To prevent scouring, the maximum permissible tractive stress on bed is 10 N/m\(^2\). The maximum slope of the channel bed to prevent scouring is 1 in \(n\). The value of \(n\) is (in integer).
