Groin-Associated Rip Currents Measured Using a New Digital Current Meter
<p>Rip currents have often been noted in physical model studies of groins and their effectiveness. Nevertheless, detailed field investigations of rip currents along a groin wall have not been heretofore conducted. A new digital current meter system was designed and built to study the …

Hydrodynamic and morphodynamic responses to surfzone seafloor perturbations
… of the subsequent evolution of waves, currents, and the modified seafloor were used to investigate nearshore dynamics. In one set of seafloor perturbation experiments, deep holes with steeply sloping sides were excavated in the inner surfzone seafloor. Observations of the infilling …

Observations of surfzone vorticity using optical remote sensing
… as they reach shallow water near the shore. Currents and circulation patterns in the surfzone transport sediment, nutrients, pollutants, and other materials along and across the coast, and can create hazardous conditions for swimmers (rip currents). However, understanding of the strength and …

Eco-geomorphological and hydrodynamic analysis of Mediterranean microtidal beaches in Southern Sardinia
… of this thesis was the numerical modelling of currents circulation within the surf zone of embayed beaches (a common beach type along the studied coastlines). Numerical modelling highlighted that wind forcing on the sea surface plays a crucial role in the formation and location of rip currents, …

Hydrodynamics, sediment transport and morphodynamics at inlets and river mouths: a numerical investigation
… ☐ 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, the model is validated with observations of waves and currents at 30 …

3-D Modeling of Nearshore Circulation Using ROMS-SWAN: Model Upgrades and Evaluation
… oblique incidence of waves on a planar beach, rip current formation in alongshore bar trough morphology (e.g., Haas and Warner, 2009). In this thesis, I present an updated version of the coupled model which implements a new vertical distribution of the radiation stress term based on Mellor …
