It’s necessary to obtain the elevation of the crest of a weir in a channel without stopping the flow. The water surface elevation upstream of the weir is 96.1 ft above mean sea level (MSL). Determine the elevation of the crest of the weir above MSL if the weir is 4.90 ft wide and discharges 30.9 ft3/s

A sluice gate is used to control and measure the discharge in an open channel, when the upstream and downstream water depths are 1.0 m and 0.2 m respectively. Calculate the discharge in the channel

A rectangular channel with a width of 8 feet conveys a discharge of 125 cfs. Find the critical depth of the channel

You need to design a hydraulic jump in a channel downstream of a gate.  A total flow of 396 cfs is moving through a concrete rectangular channel. The width of the channel is 17 ft wide.  The flow depth of flow in the upstream reach of the channel is 1.55.  Calculate the depth of flow downstream

the river flow passes through a 2.08 wide rectangular sharp crested weir. If the water level several meter upstream is 1.4 m what is the discharge (m^3/s) over the weir given that the flow reaches 0.1m above the crest? assume cw=0.637 and do not consider the velocity approach

During major flood events water flows over the top of a roadway. (a) Determine the head (H) on the broad-crested weir for a discharge rate of 15,000 cfs if the overflow section of roadway is horizontal and 500 ft long. Assume a discharge coefficient of 0.33. (b) Assume that a vehicle stalled on the roadway will be washed off the roadway into the downstream channel if the water depth exceeds 4.0 ft. Compute the water depth and velocity on the roadway. Will a stalled vehicle on the roadway remain on the road during the flood?

A 6.0 m rectangular channel carries a of 30 m³/s at a depth of 2.5 m. the channel width that produces discharge Determine the critical depth.
