Turbidity Currents and Seabed Morphology
Our main goal is to assess the hydrodynamics of turbidity currents and mudflows and their ability to produce morphological features such as ripples, dunes, antidunes and gullies along their paths. Of particular interest is to elucidate the role played by turbidity currents on the inception of submarine channels and canyons. To this end, understanding the mechanics of sediment erosion, including...
متن کاملTurbidity Currents and Their Deposits
The article surveys the current state of our understanding of turbidity currents, with an emphasis on their fluid mechanics. It highlights the significant role these currents play within the global sediment cycle, and their importance in environmental processes and in the formation of hydrocarbon reservoirs. Events and mechanisms governing the initiation of turbidity currents are reviewed, alon...
متن کاملSandwave migration in Monterey Submarine Canyon, Central California
Repeated high-resolution multibeam bathymetric surveys from 2002 through 2006 at the head of theMonterey Submarine Canyon reveal a sandwave field along the canyon axis between 20 and 250 m water depth. These sandwaves range in wavelength from 20 to 70 m and 1 to 3 m in height. A quantitative measure was devised to determine the direction of sandwave migration based on the asymmetry of their pro...
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 کاملIdentification of Temporal Shifting Trends of Submarine Indus Canyon, Pakistan
Indus Canyon is one of the most prominent sub-aqueous features of the Indus Delta. Indus River, originating from the Manasarovour Lake, hosting at the foot of high Himalayan Mountains Glaciers, forms a huge delta after travelling more than 300 km at the north eastern coastline of the Arabian Sea. In view to assess the temporal geomorphic change associated with the Indus Canyon, a study has been...
