Wave Group Forcing of Low Frequency Surf Zone Motion
The nearshore potential vorticity balance of Bowen and Holman (1989) is expanded to include the forcing from wave group-induced radiation stresses. Model results suggest that the forcing from these radiation stresses can drive oscillations in the longshore current that have a spatial structure similar to linear shear instabilities of the longshore current. In addition, the forced response is ne...
متن کاملSurf Zone Wave Breaking Identification Using Marine Radar
This paper presents a novel combination of synchronous, large coverage marine radar, calibrated pulsed Doppler radar, and video remote sensing observations from a nearshore field site. The data enable the analysis of the evolution and characteristics of the remotely observed signals from surf zone waves. The combination of different remote sensors allows a better discrimination between breaking...
متن کاملOn the Choice of Random Wave Simulation in the Surf Zone Processes
In this paper, the two common approaches to account for wave randomness, the spectral approach and the wave-bywave approach, are compared through numerical experiments conducted with the coupling of a surf zone hydrodynamic model and a bedload sediment transport model. Special attention is paid to the wave nonlinearity and net cross-shore bedload transport predictions. The two approaches are fo...
متن کاملRelationship between head wave amplitudes and seismic refraction velocities to detect lateral variation in the refractor
Refractor ambiguities are big problem in seismic refraction method especially in seismic engineering. There can be hidden subsurface geological phenomena such as hidden faults and shear zones which are not simply predicted by the travel-time graph or some geophysical methods. Head wave amplitudes are used to show the resolution of refractor ambiguities and the existence of anisotropy in complex...
متن کاملWave Reflection and Refraction at the Interface of Triclinic and Liquid Medium
A Mathematical model has been considered to study the reflection and refraction phenomenon of plane wave at the interface of an isotropic liquid medium and a triclinic (anisotropic) half-space. The incident plane qP wave generates three types of reflected waves namely quasi-P (qP), quasi-SV (qSV) and quasi-SH (qSH) waves in the tric...
