A continental shelf bottom boundary layer model : the effects of waves, currents, and a movable bed
… wave and current flow over a moveable sediment bed. An eddy diffusivity closure scheme that includes the effect of suspended sediment, temperature, and salinity induced stratification on the vertical turbulent diffusion of mass and momentum couples the resulting unsteady conservation equations …

Simple models for turbulent wave-current bottom boundary layer flow : theoretical formulations and applications
… models are developed for each model using fixed bed laboratory data and movable bed laboratory and field data. Wave attenuation measurements and current profile data are used in order to investigate the bottom roughness length scale for the cases of pure waves, waves in the presence of a current, …

The effect of dikes on water surfaces in a mobile bed
… on flood levels, this study considers effect of movable bed, which has been largely neglected in previous studies. Previous research on this topic has relied on field data, numerical modeling and physical modeling. A majority of the modeling has been a fixed bed condition and has not accounted …

Turbulent combined wave-current boundary layer model for application in coastal waters
… Boundary layer models require an estimate of the movable bed roughness, and while this roughness is scaled by the sand grain diameter for flat beds, in the coastal environment it is often the case that either wave-generated ripples cover the bed or the near-bed sediment is transported as sheet …

3-D Numerical Simulation Of Dam-Break Flows Over Movable Beds
Irvin Cooper was a prominent music educator in boys’ adolescent voice change research. Dr. Cooper developed the Cambiata concept as a method for teaching boys to sing throughout the voice change. This method was starkly different from the traditional model that encouraged the changing voice to be …

Controls on and Morphodynamic Effects of Width Variations in Bed-load Dominated Alluvial Channels: Experimental and Numerical Study
… factors, and quantification of the riverbed morphodynamic response to width variability is of crucial importance to support effective river management. The practical and engineering interest on stable cross-sections of alluvial channels has attracted a considerable amount of scientific …
