Ambient noise from turbidity currents
The Journal of the Acoustical Society of America, 2017Sediment mass transport from the Squamish River delta into the adjacent fjord (Howe Sound, British Columbia) is dominated by discrete turbidity current events which have incised semi-permanent channels on the delta front and out onto the prodelta. Acoustic data were collected in the spring of 2013, including both active and passive systems.

Turbidity Currents and Their Deposits
Annual Review of Fluid Mechanics, 2010The 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.

Flow structure in turbidity currents
Journal of Hydraulic Research, 1996AThis article presents a series of experiments with turbidity currents using two different types of sediments. During these experiments, the distributions of the velocity and of the concentration were measured simultaneously at three stations. The results show that the nondimensional velocity distribution is relatively insensitive to large variations ...

Turbidity-Current Experiments: ABSTRACT
AAPG Bulletin, 1966Experiments were performed in the W. M. Keck Laboratory, California Institute of Technology, using a lucite channel 5 meters long, 50 cm. deep, and 15.4 cm. wide. Turbidity-current "surges" were produced by releasing suspensions of plastic beads from a lock at one end of the channel.

Hydraulic Jumps in Turbidity Currents
Geological Society of America Bulletin, 1971If uniform flow conditions are approached, turbidity currents should be supercritical (Froude number greater than unity) while passing through submarine canyons, and subcritical (Froude number less than unity) in the upper submarine fan channel. The change in flow regime requires that the current pass through a hydraulic jump in the vicinity of the ...

Flow structure of turbidity currents
Sedimentology, 2002AbstractA two‐dimensional numerical model is used to describe the flow structure of turbidity currents in a vertical plane. To test the accuracy of the model, it is applied to historical flows in Bute Inlet and the Grand Banks flow. The two‐dimensional spatial and temporal distributions of velocity and sediment concentration and non‐dimensionalized ...

Turbidity Currents and Seabed Morphology
2004Abstract : 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.

Orleansville Earthquake and Turbidity Currents
AAPG Bulletin, 1955An earthquake of magnitude 6.7 violently shook the area near Orleansville, Algeria, on September 9, 1954. The area of appreciable damage extended 15 miles from the epicenter, and following the earthquake five submarine cables lying on the floor of the Mediterranean Sea broke at distances of 40-70 miles northwest of the epicenter.

Effect of sedimentation on 3D turbidity currents
2009In this paper a mathematical model for 3D turbidity currents has been presented. The model consists in a system of partial differential equations in conservative form, formulated in the framework of the shallow water equations and it accounts for the main features of the turbidity currents: entrainment of environment fluid, settling and resuspension of

Turbid Density Currents in Reservoirs
Water International, 1986ABSTRACT Physical features of turbid density currents in reservoirs are touched on in the first part of this paper: the plunging of the muddy fluid, the unsteadiness of the density current, the characteristics of velocity and concentration of density currents, the density current over a submerged dam and the submerged muddy lake formed by the density ...
