Wave-induced rip currents on barred planar beaches are using ADCIRC- 2DDI, a two-dimensional finite-element hydrodynamic model. Surface wave stress gradients, determined form REF/DIF1, a phase-resolving monochromatic wave model that simulates refraction, diffraction, and wave breaking, are used to force the ADCIRC model. The rip current circulation on an ideal barred beach, approximately 1 sq km in area with a single channel in the center of its alongshore bar, is investigated. ...
Alongshore currents and nearshore dynamics generated on plane and barred beaches are successfully simulated using a shallow water model, ADCIRC, whose traditional applications have been focused on shelf-scale processes. ADCIRC-2DDI is a two-dimensional, finite-element-based coastal circulation model. Wave fields obtained from REF/DIFI, a monochromatic wave model that simulates refraction, diffraction, and wave breaking, are used to compute surface wave radiation stress gradients that force the hydrodynamic model. Processes such as ...
This study focuses on modeling the 2D, depth-averaged circulation of Bay St. Louis in the northeastern Gulf of Mexico that is driven by waves and tides using a coupled hydrodynamic-wave model. The wave-tide coupled circulation within the inlet is examined during the flood, slack, and ebb phases of the tidal cycle. The wave height field, current velocity and sea surface elevation are analyzed to determine the effects of wave-current interaction. ...
