Observations and modeling of wave-acceleration-induced sediment transport in the surfzone
Onshore sediment transport and sandbar migration are important to the morphological evolution of beaches, but are not understood well. Here, a new model that accounts for accelerations of wave-orbital velocities predicts onshore sandbar migration observed on an ocean beach. In both the observations …

Multi-scale modeling of the hydrodynamics, sediment transport, and morphodynamics in the nearshore
… model, hydrodynamics and morphodynamics during sandbar migration events at Duck, NC, USA were simulated under high-energy and low-energy incident waves. It was found that the model calculations of intense offshore-directed flow referred to as undertow is highly dependent on the wave roller …

Advancement of Using Portable Free Fall Penetrometers for Geotechnical Site Characterization of Energetic Sandy Nearshore Areas
… variations in sediment strength to wave climate, sandbar migration, and depth of closure, as well as identifying areas of significant sediment mobilization processes; and (3) estimating the relative density and friction angle of sand in energetic nearshore areas from PFFP measurements. For the …

Hydrodynamics, sediment transport and morphodynamics at inlets and river mouths: a numerical investigation
… nearshore wave-current interaction and sandbar migration are evaluated. ☐ The interactions between waves, tidal currents, and bathymetry near New River Inlet, NC, USA are then investigated to understand the effects on the resulting hydrodynamics and sediment transport. Using NearCoM-TVD, …
