Abstract

Validated hindcast storm currents and waves are used to drive a coupled bottom boundary layer-sediment transport model for Hurricane Andrew. Shear stresses and suspended sediment profiles are computed using a combined wavecurrent bottom boundary layer model with variable bottom roughness. The sedimentation model calculates suspended sediment profiles, and suspended and bed load transport rates. Sediment erosion and deposition is found using mass conservation equations with advection and diffusion terms. The average model-predicted combined resuspension-advection sediment thickness during a 1-hour interval at the storm peak is less than 0.04 m, with a maximum of more than 2.6 m.
