Simplified 2D Sediment Modeling with HEC-RAS ("Capacity Only" and "Concentration Only" Modes)
HEC has added some simplified, "fixed bed," sediment transport options to the 2D Sediment model. Stanford Gibson gave this presentation to the Corps' River Engineering Working Group about how the tools developed, what they do, and how they have been applied.
