Flow structure of turbidity currents

Sedimentology, 2002
AbstractA 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

2004
Abstract : 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, 1955
An 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

2009
In 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, 1986
ABSTRACT 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 ...

Turbidity Currents and Petroleum Exploration

AAPG Bulletin, 1954
Application of theories of deposition by turbidity currents solves several geologic problems. Deposits of turbidity currents on shelves and in mobile belts have distinct characteristics. Familiarity with some of these characteristics can considerably help the exploration geologist.

Turbidity Currents, Bedforms, and Gullies

2001
Abstract : Our main goal is the development of physically-based models for submarine sediment movement that can be used to predict the initiation, spatial development, and time duration of mud flows and turbidity currents. Of particular interest are the characteristics of the sedimentary deposits generated by density underflows, mainly their capability

Possible Quick-Clay Motion in Turbidity Currents

Science, 1962
Sensitive clay masses that lie dormant for years but, as the result of a sudden shock, become turbulent, flowing mud, have been called quick clays. Such masses may move in quantity over almost flat terrain, and they exhibit the power to transport buildings and other heavy objects considerable distances. On theoretical grounds it is proposed that one of
