The velocity and depth of flow in a 3.0 m wide rectangular channel are 2.0 m/s and 2.5 m/s respectively. If the channel has it's width enlarged to 3.5 m at a section, the discharge past section is
Read the question carefully and give me both right solutions with clear calculations. A trapezoidal canal has one side vertical and the other sloping 1:1. The discharge is known to be 20 m3 /s at a mean velocity of 1.2 m/s. If the slope is to be minimum as possible, and n=0.015, (a) At what depth is it flowing in m? (b)What is the value of this minimum slope?

(b) Water is flowing uniformly with flow rate 18.6 m3/s and water depth 1.2 m in a rectangular open channel of width 8 m. A temporary short span bridge is proposed to be constructed across the channel in which bridge embankment is needed at both sides of the channel causing the channel to be constricted under the proposed bridge. (i) Calculate the maximum channel width under the proposed bridge that will not cause backwater upstream.
