A rectangular channel 6 m wide and 1.5 m deep has a slope of 1 in 1200 and is lined with good rubble masonry, for which Manning's, n = 0.019. It is desired to increase the discharge to a maximum by changing the section. The dimensions of the section may be changed but the channel must contain the same amount of lining. The percentage increase in discharge is

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.
