First wide-angle view of channelized turbidity currents links migrating cyclic steps to flow characteristics [PDF]
Nature Communications, 2016 The basal structure of turbidity currents and their association with crescent-shaped bedforms has not been observed at the field scale. Here, the author presents views of turbidity currents moving over and modifying such bedforms in a manner consistent ...

Powerful turbidity currents driven by dense basal layers [PDF]
Nature Communications, 2018 The structure of turbidity currents has remained unresolved mainly due to lack of observations. Here the authors present data from a high-resolution monitoring array deployed for 18 months over Monterey Bay, that suggests turbidity currents are driven by

Underwater noise from submarine turbidity currents [PDF]
JASA Express Letters, 2021 Noise from turbidity currents flowing down the face of a fjord delta was measured underwater at frequencies from 1 to 1200 kHz. The noise spectra are consistent with sound generation by collisions among sand-sized particles.

Direct observations of bedform migration driven by turbidity currents in a lacustrine channel [PDF]
Scientific ReportsTurbidity currents, gravity-driven sediment-laden flows, govern material transport and shape underwater landscapes across diverse environments. While extensively studied in marine settings, their dynamics in freshwater systems remain underexplored.

Flow behaviour of ponded turbidity currents [PDF]
Journal of Sedimentary Research, 2015 Sea floor topography can constrict, deflect or reflect turbidity currents resulting in a range of distinctive deposits. Where flows rebound off slopes and a suspension cloud collects in an enclosed basin, ponded or contained turbidites are deposited ...

Ocean-bottom seismometers reveal surge dynamics in Earth’s longest-runout sediment flows [PDF]
Communications Earth & EnvironmentTurbidity currents carve Earth’s deepest canyons, form Earth’s largest sediment deposits, and break seabed telecommunications cables. Directly measuring turbidity currents is notoriously challenging due to their destructive impact on instruments within ...

Is it appropriate to model turbidity currents with the three-equation model? [PDF]
, 2015 The three-equation model (TEM) was developed in the 1980s to model turbidity currents (TCs) and has been widely used ever since. However, its physical justification was questioned because self-accelerating TCs simulated with the steady TEM seemed to ...

Turbidity Currents, Submarine Landslides and the 2006 Pingtung Earthquake off SW Taiwan
Terrestrial, Atmospheric and Oceanic Sciences, 2008 Submarine landslides or slumps may generate turbidity currents consisting of mixture of sediment and water. Large and fast-moving turbidity currents can incise and erode continental margins and cause damage to artificial structures such as ...

A Numerical Investigation of Transformation Rates from Debris Flows to Turbidity Currents under Shearing Mechanisms [PDF]
Applied Sciences, 2023 The evolution of a submarine landslide is a very complicated process due to slurry–water interactions. Most previous studies have focused on debris flows or turbidity currents independently.
