Flow Near Submarine Canyons Driven by Constant Winds
Circulation over coastal submarine canyons driven by constant upwelling or downwelling wind stress is simulated and analyzed with a primitive equation ocean model. Astoria Canyon, on the west coast of North America, is the focus of this study, and model results are consistent with most major features of mean canyon circulation observed in Astoria Canyon. Near-surface flow crosses over the canyo...
متن کاملRip Currents Onshore Submarine Canyons
The long-term goals of this research are to understand the dynamics of rip currents generated by largescale variations in alongshore pressure gradients and wave forcing, and the impact of rip currents on nearshore bathymetry. These goals will be accomplished collaboratively using field observations and numerical models, and will be pursued as part of the Nearshore Canyon Experiment (NCEX) sched...
متن کاملCirculation Near Submarine Canyons: A Modeling Study
Circulation near a submarine canyon is analyzed with a numerical model. Previous theoretical work indicated that stratification controlled the interaction of coastal flow with canyons, specifically, the ratio of canyon width to the internal radius of deformation. A wide canyon was thought to merely steer the flow, while a narrow canyon would create substantia• cross-shelf exchange. Four cases a...

The long-term goals of this research are to understand the dynamics of rip currents generated by largescale variations in alongshore pressure gradients and wave forcing, and the impact of rip currents on nearshore bathymetry. These goals will be accomplished collaboratively using field observations obtained as part of the Nearshore Canyon Experiment (NCEX) held in the fall of 2003 and with nume...
