Three approaches can be used in HEC-RAS for stable channel design. They are the Copeland, Regime, and Tractive Force methods. The Copeland method uses an analytical approach to solve stable channel design variables of depth, width, and slope. Stability is achieved when the sediment inflow to a particular reach equals the sediment outflow. The Regime method is purely empirical, and, within HEC-RAS, uses equations developed by Blench (1975). The Regime method defines a channel as being stable when there is no net annual scour or deposition in the design reach. The Tractive Force method is an analytical scheme that defines channel stability as no appreciable bed load movement. It is important to know the characteristics of the design stream to determine which approach will work best. Each of these approaches stem from work done previously in conditions with somewhat limited validity ranges.
