Systematic stable channel design methods are currently being developed by the US Army Engineer Waterways Experiment Station for use in the planning stages of local flood control projects. An analytical approach has been developed that couples resistance and sediment transport equation to solve for the channel dimensions of width, depth, and slope. A family of solutions for width and slope is obtained. The method is based on a typical trapezoidal cross section and assumes steady uniform flow. The method is especially applicable to small streams because it accounts for sediment transport, bed form roughness, and bank roughness.
