A rectangular stream channel is 300 ft wide and carries a flow of 15,000 cfs. The depth of flow is 10 ft. A bridge with symmetric embankments is to be constructed over the channel. Without considering head losses, determine the depth of flow in the constriction (y2 ) and upstream of the bridge (y3) for bridge lengths (B) of 250 ft, 200 ft, 150 ft, 100 ft and 50 ft.
