Alongshore sediment bypassing as a control on river mouth morphodynamics

Interactions of Waves and River Plume and their Effects on Sediment Transport at River Mouth

Sediment Transport Modelling for Coastal Morphodynamics

The accurate prediction of sand transport rates in the coastal zone depends not only upon the choice of sediment transport model but also, rather critically, upon the formulation used to predict the bed roughness (ks). Sand transport rates are modelled here using both a One-equation, turbulence-closure, TKE-model and also Bijker’s sand transport model. Following some remarks about the nature an...

Interactions of Waves and River Plume and their Effects on Sediment Transport at River Mouth (RIVET I)

The interaction between the hydrodynamics and complex bathymetry can produce highly heterogeneous and locally energetic flows, e.g., in a tidal inlet dominated by tidal flow and wave-current interaction. Consequently, the morphological evolution around such tidal inlet also becomes very dynamic. These two factors cause concerns over navigation safety especially in areas where routine surveys ar...

Backwater and river plume controls on scour upstream of river mouths: Implications for fluvio-deltaic morphodynamics

[1] Sediment flux from rivers to oceans is the fundamental driver of fluvio-deltaic morphodynamics and continental margin sedimentation, yet sediment transport across the river-to-marine boundary is poorly understood. Coastal rivers typically are affected by backwater, a zone of spatially decelerating flow that is transitional between normal flow upstream and the offshore river plume. Flow dece...
