A road across the main channel just downstream of the watershed in Problem 10.32 is a low water crossing structure shown below. The weir length is 61.0 m (200 ft) and the weir coefficient is 0.35. Compute the maximum depth on the roadway before and after the watershed has been developed. During the 100-year flood event, how long will it take for the depth of water on the roadway to increase from 0.30 m (1.0 ft) to 0.61 m (2.0 ft) after the watershed has been developed? Neglect upstream storage.
