Abstract:

My long-term goal is to develop physics-based models to predict nearshore morphology changes, and to test the models against available field data. The objectives of the present project are to 1. Incorporate a sediment transport and bed morphology capability in the wave-induced circulation model of Ozkan-Haller and Kirby 1997, 1999 2. Use the resulting model to study the growth to finite amplitude of bottom perturbations on initially longshore-uniform planar or barred beaches 3. Use the model to investigate the evolution of three-dimensional bed features under specific wave conditions, in comparison to ARGUS video results for the Duck FRF site. 4. Begin the development of an instantaneous sediment transport capability on a wave by wave basis in the Boussinesq model of Wei et al 1995.
