Wave Attenuation on Muddy Bottoms – A Multidisciplinary Field Study Offshore Cassino Beach, Southern Brazil
A field experiment was performed offshore Cassino Beach, Southern Brazil. In this area mud deposits were observed, mainly originated from the Patos Lagoon. Episodically, and associated with storm waves able to transport the mud from offshore to the beach, the usual sandy beach is covered by mud. This is a unique process along the Brazilian coastline, and the field experiment aimed to record the...
متن کاملWave-Sediment Interaction in Muddy Environments: A Field Experiment
The objectives of Years 1 and 2 (2007-2008) of the Coastal Geosciences (CGS) project was to conduct a pilot field experiment (2007), then a full field experiment (2008), in collaboration with other researchers funded by ONR CG program. The pilot experiment has tested the instrumentation and data analysis procedures. During the major field experiment effort in 2008 (Year 2), a total of 5 tripods...
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...
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 کاملScaling surf zone turbulence
[1] Turbulence in the surf zone, the shallow region adjacent to the shoreline, has a key role in beach erosion, fertilization, dispersal, and larval settlement of marine invertebrates, and microbial contamination dilution in beach waters. Breakingwave generated (the dominant source) surf zone turbulence is understood poorly. A new surf zone turbulent dissipation rate scaling is derived, that co...
