Shoaling Wave Energy Dissipation in Turbulent Bottom Boundary Layers

Abstract

The long term goal is to increase the understanding and predictive capability for effects of turbulent bottom boundary layers on shoaling wave fields. The primary objectives are to make direct estimates of wave energy dissipation rates that occur in the boundary layer for different wave field conditions and to use three-dimensional direct numerical simulations to evaluate one-dimensional eddy viscosity models such as proposed by Trowbridge and Madsen (1984) and Fredsoe and Deigaard (1992). We are also examining the vertical transport of mass and momentum within the boundary layer by turbulent diffusion and differences between oscillatory boundary layers and steady uni-directional flows.
