In the research conducted under this project, models were developed which predict channel erosion resulting from shear in gradually varied flow, shearing forces resulting from submerged jets and hydraulic jumps, and shearing forces resulting from free jets impinging a plunge pool. These models are linked with a runoff routing algorithm to develop the CHANNEL model. This model predicts general channel erosion resulting from time varying gradually varied now as well as predicts the development and propagation of channel headwalls. At this writing, the model still has some problems handling the transition from open channel now to a free jet within the scour hole.
