On the Scaling of Sediment Transport in the Nearshore Introduction
This paper investigates the scaling of sediment transport by waves in the nearshore. Scaling of sediment is often needed in laboratory wave flumes where spatial dimensions are about a factor 10 smaller. Generally, for the physical model, normal sand is chosen with a relatively small diameter. Scaling relations are consulted to translate the spatial dimension and sediment flux to prototype value...
متن کاملParameterization of Time-Averaged Suspended Sediment Concentration in the Nearshore
To quantify the effect of wave breaking turbulence on sediment transport in the nearshore, the vertical distribution of time-averaged suspended sediment concentration (SSC) in the surf zone was parameterized in terms of the turbulent kinetic energy (TKE) at different cross-shore locations, including the bar crest, bar trough, and inner surf zone. Using data from a large-scale laboratory experim...
متن کاملstudy on the transport of sediment oxygen demand -related organicmatter in bottom sediment system
approach of organic material anaerobic biodegradation and species of organic matter in sediment are discussed, and then a classifying method of the species is proposed on a new viewpoint. the pore water sediment oxygen demand (sod) numerical model in bottom sediment system is proposed originally, which differs from other advection-dispersion-sorption (ads) model in adding a sod-creating term. t...
متن کاملA Nearshore Model to Investigate the Effects of Seagrass Bed Geometry on Wave Attenuation and Suspended Sediment Transport
The effects of seagrass bed geometry on wave attenuation and suspended sediment transport were investigated using a modified Nearshore Community Model (NearCoM). The model was enhanced to account for cohesive sediment erosion and deposition, sediment transport, combined wave and current shear stresses, and seagrass effects on drag. Expressions for seagrass drag as a function of seagrass shoot d...
متن کاملSediment Formation in Nearshore Environments: Strength, Rheology, Microstructure, and Stability
Our goals are to understand how geotechnical and physical properties develop in marine sedimentary deposits on continental margins and how these properties influence sediment transport processes and the development of geomorphology. Our studies include predicting stability of sediment on the continental shelf and slope, providing input parameters for models of sediment transport and deformation...
