Wave-Driven Longshore Currents in the Surf Zone Hydrodynamic validation of Delft3D
Recent study has shown that 3D computations of the morphological development of a coast shows irregularities compared with the 2DH (depth-averaged) computations. Therefore a validation of the surf zone currents computed using the 2DH (depth-averaged) and 3D approach in Delft3D is made. The 2DH and 3D approach are compared using an idealized case and validated using data from the laboratory expe...
متن کاملExtreme water velocities: Topographical amplification of wave-induced flow in the surf zone of rocky shores
Water velocities as high as 25 m s21 have been recorded in the surf zone of wave-swept rocky shores—velocities more than twice the phase speed of the breaking waves with which they are associated. How can water travel twice as fast as the waveform that initially induces its velocity? We explore the possibility that the interaction of a wave with the local topography of the shore can greatly amp...
متن کاملWave 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...

15 صفحه اولSurf 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...
