A triangular roadside drainage channel is to be designed to carry a design dischargeof 12.5cfs. The steepest part of the channel has a ground slope of 200H:1V. The channel is to be plantedwith a fescue blend (n=0.04). The maximum side slope is 10H:1V. The client requires that the channeldepth (normal plus freeboard) be less than 1ft. Would the channel suffice if designed around themaximum side slope? If not, recommend 3 unique ways that the channel could be redesigned to satisfythe client's restriction.
