Mechanics of Sediment Transport by the Combination of Waves and Current

The motivation to develop a transport formulation for the combination of waves and current has been the necessity to model longshore transport passing tidal in- and outlets. The generally applied C.E.R.C. formula for the longshore transport is not applicable here because that formula relates the longshore transport to the longshore current...

Diffusion of sediment in a non-uniform flow field

The suspension of sediment particles by turbulent eddy diffusion in a non- uniform flow region was studied, using the convective-diffusion equation as a mathematical model. A simplified form of the equation for which mixing characteristics and flow velocities 'vere assumed uniform was found to accurately describe the sediment concentration...
