Channel, A Model Of Channel Erosion By Shear, Scour And Channel Headwall Propagation: Part 1. Model Development, Alex W. Fogle, Billy J. Barfield

KWRRI Research Reports

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 …

Hydraulic And Sediment Transport Studies In Relation To River Sediment Control And Solid Waste Pollution And Economic Use Of The By-Products, Bruce R. Moore, Michael R. Short

KWRRI Research Reports

The distribution of sediments and conditions of transport were studied in the Kentucky, Big Sandy and Ohio Rivers. The sand and coal were in transport at different flow velocities for the rivers and the deposition of these sediments was a direct function of the flow conditions at a particular locality.

The flow conditions of transport of the sediments were studied in flumes as were the hydraulic conditions in model dredge holes to determine the feasibility of trapping sediment. The conditions of scour and fill were also established and compared with known conditions in a dredge hole in the Ohio River. …
