The channel bottom at the junction of two rectangular channels is raised by 0.1 m. The upstream channel is 10 m wide and the downstream channel is 8 m wide. If the channel discharge is 10 m/sec and the depth in the upstream channel is 1.5 m, determine the flow depth downstream of the junction assuming the losses at the junction to be 0.2 V /(2g), where is the flow velocity in the downstream channel
