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 کاملVenting of Turbidity Currents: When to Act?
During floods, sediments are transported from watersheds into reservoirs, slowly decreasing water volumes and this leading to economic losses. Thus, in the long term, sedimentation endangers reservoirs’ sustainability. Sediments can also block low-level hydraulic structures such as bottom outlets and powerhouse intakes and cause abrasion of gates and turbines. Additionally, the trapped sediment...
متن کاملeffect of turbidity currents on sedimentation process in sefidroud dam
abstract turbidity current is one of the most important factors that effect the sediments distribution and also their transportation and release from reservoir. in this study, effects of these currents on sedimentation process in sefidroud dam were simulated by tcm model in 30 years period. comparison between the case of turbidity currents that reach to the dam wall and release from the reservo...
متن کاملTrapping of sustained turbidity currents by intraslope minibasins
Depositional turbidity currents have filled many intraslope minibasins with sediment creating targets for petroleum exploration. The dynamics of sustained turbidity currents and their depositional characteristics are investigated in a scaled physical model of a minibasin. Each turbidity current deposited a downstream thinning wedge of sediment near the inlet. Farther downstream the turbidity cu...
