Curvature-induced secondary flow in submarine channels
Environmental Fluid Mechanics, 2014The curvature-driven secondary flow in sinuous submarine channels has been a subject of considerable interest and controversy. Here, results from numerical model studies involving saline flow in laboratory-scale channels are presented. A 3D finite volume model of density and turbidity currents is used and simulations are run with different inflow ...

Controls on sinuosity evolution within submarine channels
Geology, 2008The planform geometry of submarine channels commonly exhibits a spatio-temporal stability generally not observed in fluvial channels. As such, submarine channels tend to lack the meander loop cutoffs and frequent avulsion history typical of fluvial channels. fluvial sinuosity develops through inner-bend deposition and outer-bend erosion.

Characterisation of Submarine Acoustic Transmission Channels
1981Some experimental results about an active characterisation of the submarine acoustic horizontal and middle range propagation are given. First simultaneous monochromatic signals are emitted which lead to the analysis of power and phase fluctuations. Then high — product BT signals are used to estimate the channel bitemporal response and the scattering ...

How submarine channels (re)shape continental margins
Journal of Sedimentary Research, 2020ABSTRACTSubmarine landscapes, like their terrestrial counterparts, are sculpted by autogenic sedimentary processes toward morphologies at equilibrium with their allogenic controls. While submarine channels and nearby, inter-channel continental-margin areas share boundary conditions (e.g., terrestrial sediment supply, tectonic deformation), there are ...

Slope Control on Submarine Channel Widths
Journal of Sedimentary Research, 2008Abstract Submarine channel systems associated with turbidity currents show characteristic variations in channel width and channel slope with distance from source. The most proximal parts are generally formed from pre-existing canyons but these are followed by channels which show segments with two distinct behaviors: (1) sections where channel width is ...

Submarine depth control by individual channel design
Proceedings of the 37th IEEE Conference on Decision and Control (Cat. No.98CH36171), 2002The analysis of submarine control design under the framework of individual channel design (ICD) is presented. The boat considered corresponds to the 80 metres standard British submarine. It is shown that under the ICD framework the multivariable control design of submarines can be solved, in an effective and clear manner, by applying classical ...

Experiments on incipient channelization of submarine fans
Journal of Hydraulic Research, 2002Experiments on the formation of channelized submarine fans by the passage of successive turbidity currents are presented. Channels similar to subaerial rivers are found in many submarine fans. The inception of channels on submarine fans, which are essentially depositional environments, can be explained in terms of the lateral distribution of the rates ...

Global (latitudinal) variation in submarine channel sinuosity
Geology, 2012Current classifications of submarine channels and fans link channel sinuosity to gradient, and in turn to sediment caliber, with end members being high-sinuosity, low-gradient, finegrained systems and low-sinuosity, high-gradient, coarse-grained systems.
