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?
