Abstract: A combination of hydraulic and geotechnical techniques have been applied to predict future cross-section morphology in incised channels. The SAM program (Copeland, 1991) computes combinations of width, slope, and depth that satisfy sediment and water discharge continuity for input data describing the bed sediment, bank angle and roughness, discharge and sediment concentration. The techniques described by Osman and Thorne (1985) were used to predict slab-failure bank instability. Preliminary results indicate that the use of SAM in conjunction with Osman and Thorne may be of value.
