On the modeling of wave-enhanced turbulence nearshore

Numerical modeling of the effects of wave energy converter characteristics on nearshore wave conditions

Modeled nearshore wave propagation was investigated downstream of simulated wave energy converters (WECs) to evaluate overall nearand far-field effects of WEC arrays. Model sensitivity to WEC characteristics and WEC array deployment scenarios was evaluated using a modified version of an industry standard wave model, Simulating WAves Nearshore (SWAN), which allows the incorporation of device-spe...

Nearshore Wave Modeling with High-Order Boussinesq-Type Equations

The accuracy of using high-order Boussinesq-type models as compared to the typical order models is examined in this paper. The high-order model used is the two-layer model of Lynett and Liu in 2004, which captures both linear and nonlinear wave evolution up to kh 6. The physical situations examined all involve nearshore breaking, and an eddy-viscosity type breaking model is adopted for the two-...

Nearshore Wave-topography Interactions

The principal focus of this program has been on understanding the nearshore problem from a top down point of view. At time scales longer than storm periods and length scales larger than 100 meters, the behavior of the nearshore appears surprisingly complex, with subtantial interannual variability and variability on all scales. We believe that this results from feedback between the fluid and bat...

Turbulence Modeling and Wave-Current Interactions

The mechanics of rip currents are complex, involving interactions between waves, currents, water levels and the bathymetry, that present particular challenges for numerical models. Here, the effects of a grid-spacing dependent horizontal mixing on the wave-current interactions are studied. Near the shore, wave rays diverge from channels towards bar crests because of refraction by topography and...
