A coastal morphodynamic model for cross-shore sediment transport

A numerical model to represent the mechanisms of cross-shore sediment transport induced by wave and storm events has been established. The model consists of three sub-models (wave transformation, morphodynamic movement, and sedimentation) capable of representing the transport and redistribution of four grain sizes over a coastal area. It is designed to simulate the morphological evolution cause...

Turbulent Shear Stress in Heterogeneous Sediment-laden Flows

Current knowledge of the mechanics of alluvial channels depends very largely on calculations of turbulent shear stresses; typical examples are the beginning of motion of sediment particles and sediment transport in alluvial channels. If shear stress can be well defined in clear-water flows, comparatively little is known about shear stresses in sediment-laden flows. Einstein and Chien (1955) pro...

Analysis of Velocity Lag in Sediment-laden Open Channel Flows

Laboratory experiments have recently confirmed that the streamwise particle velocity is largely less than that of the fluid in sediment-laden flows. This velocity lag is investigated analytically in the present study based on the drag force exerting on a particle in the presence of other neighbors. The normalized drag force or the hindrance coefficient is found generally dependent on the partic...

Granular and Particle-Laden Flows

This research programme at the Newton Institute was devoted to improving the understanding and mathematical modelling of granular and particle-laden fluid systems as they arise in nature, in the laboratory and in industry. Geophysical examples of granular and particle-laden flows include rock avalanches, debris flows, mud flows and turbulent boundary layers with suspended particles, such as vol...

Sluicing Flumes for Gauging Sediment-Laden Rivers

The sluicing flume that was designed is less capable of silting up and losing its calibration than its counterparts of standard sharp-crested compound weir design. The laboratory work described here led to a refinement in the design in the form of a short flume set into the lowest section of a compound Crump weir gauging installation. Critical flow occurs near the exit of this flume, and it is ...
