910. A rectangular irrigation canal is proposed with a width of 8 m. It has a uniform flow depth of 1.5 m and a flow rate of 16 m3/s. A bridge will be constructed across the canal. For the purpose of the bridge construction, an abutment is required to be built on both sides of the canal causing the channel to be constricted. (a) Calculate the maximum canal width under the bridge that will not cause backwater upstream. (b) If the canal width below the bridge is 6 m due to the unavoidable abutment construction, calculate the expected flow depth under the bridge, at just upstream and downstream of the bridge. glo.
