The role of intratidal oscillations in sediment resuspension in a diurnal, partially mixed estuary [PDF]

, 2010
Using detailed observations of the mean and turbulent properties of flow, salinity and turbidity that spanned 2001/02, we examined the physical mechanisms underpinning sediment resuspension in the low-energy Swan River estuary, Western Australia. In this

CFD-DEM modeling of turbidity current propagation in channels with two different topographic configurations

Frontiers in Marine Science, 2023
Submarine turbidity currents are a special type of sediment gravity flow responsible for turbidite deposits, attracting great interests from scientists and engineers in marine and petroleum geology. This paper presents a fully coupled computational fluid

Self-stratifying turbidity currents

, 2022
Turbidity currents, seafloor flows driven by the excess density of suspended particles, are key conveyors of sediment, nutrient, and pollutant from the continental margins to deep ocean, and pose critical submarine geohazard risks. Due to their vast scale and extreme aspect ratio, extant models are constrained to highly simplified depth-averaged theory

Longitudinal flow evolution and turbulence structure of dynamically similar, sustained, saline density and turbidity currents [PDF]

, 2006
Experimental results are presented concerning flow evolution and turbulence structure of sustained saline and turbidity flows generated on 0°, 3°, 6°, and 9° sloping ramps that terminate abruptly onto a horizontal floor.

Numerical Modeling of turbidity currents with Ansys CFX and Telemac 3D

E3S Web of Conferences, 2018
Turbidity currents may be a relevant lever to manage the accumulation of fine sediments in reservoirs. In this paper, we propose to show how two different numerical codes simulate the propagation of turbidity currents.

Sedimentary processes and architecture of Upper Cretaceous deep-sea channel deposits : a case from the Skole Nappe, Polish Outer Carpathians [PDF]

, 2018
Deep-sea channels are one of the architectonic elements, forming the main conduits for sand and gravel material in the turbidite depositional systems.

Propagation Velocity of Excitation Waves Caused by Turbidity Currents

Journal of Marine Science and Engineering
Turbidity currents are important carriers for transporting terrestrial sediment into the deep sea, facilitating the transfer of matter and energy between land and the deep sea.

Modeling of Breaching-Generated Turbidity Currents Using Large Eddy Simulation

Journal of Marine Science and Engineering, 2020
Breaching flow slides result in a turbidity current running over and directly interacting with the eroding, submarine slope surface, thereby promoting further sediment erosion. The investigation and understanding of this current are crucial, as it is the

Mitigating suspended-sediment environmental pressure in subsea engineering through colliding turbidity currents

Results in Engineering
Turbidity currents have extensively been explored in quiescent environments. However, during several underwater activities (e.g., dredging and deep sea mining), generated turbidity currents could travel in opposite directions and interact with each other,

Are flood-driven turbidity currents hot spots for priming effect in lakes? [PDF]

Biogeosciences, 2016
In deep stratified lakes, such as Lake Geneva, flood-driven turbidity currents are thought to contribute to the replenishment of deep oxygen by significant transport of river waters saturated with oxygen into the hypolimnion.
