A trapezoidal channel with sidewalls of 60 degrees has a bottom width of 4 m at total depth of 5 m and has a constant bedslope of 0.005. A flow of 40 m3/s fills the channel to a depth of 3.5 m, the maximum for normal operation. Downstream a topographic constriction requires that the channel be rectangular with a maximum width of 4 m. Assuming no changes in materials and no energy losses, estimate the depth in the downstream rectangular section and recommend a total depth for the rectangular channel.
