Total Variation Diminishing (TVD) solver is used in several coastal models, including a Boussinesq wave model, a 3D non-hydrostatic wave model, and a coupled wave-current model. The models implemented with the shock-capturing TVD scheme show robust performances in modeling breaking waves, nearshore circulation and coastal inundation. In this talk, I will present a multi-order MUSCLE-TVD scheme and a high-order adaptive time-stepping scheme in the recent developments of those coastal models. Model applications to large-scale wave simulation, tsunami generation and propagation, and coastal inundation will also be presented.
Dr. Shi's research interests include numerical modeling, nearshore processes, coastal ocean hydrodynamics and sediment transport, and tsunamis. He received his Ph.D. from the Ocean University of Qingdao, China.
