Sediment Transport and ScourSediment Transport and Scour
Develop and validate sediment transport mechanisms
Pump up of sediments due to large-scale vortices created by bore collapse.
Entrainment of local sediment by instantaneous bed shear stress.
Enhanced transport due to soil instability (momentary static liquefaction caused by high pore pressure during drawdown)
