Flow Behavior 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. Ponded turbidites have been widely recognised in slope mini-basins and on small, structurally-confined ...

The Influence of Confining Topography Orientation on Experimental Turbidity Currents and Geological Implications

Frontiers in Earth Science, 2021
Turbidity currents distribute sediment across the seafloor, forming important archives of tectonic and climatic change on the Earth’s surface. Turbidity current deposition is affected by seafloor topography, therefore understanding the interaction of ...

Evaluation of flow regime of turbidity currents entering Dez Reservoir using extended shallow water model

Water Science and Engineering, 2014
In this study, the performance of the extended shallow water model (ESWM) in evaluation of the flow regime of turbidity currents entering the Dez Reservoir was investigated. The continuity equations for fluid and particles and the Navier-Stokes equations

Newly recognized turbidity current structure can explain prolonged flushing of submarine canyons [PDF]

, 2016
Seabed-hugging flows called turbidity currents are the volumetrically most important process transporting sediment across our planet and form its largest sediment accumulations.

High-resolution simulations of turbidity currents

Progress in Earth and Planetary Science, 2017
We employ direct numerical simulations of the three-dimensional Navier-Stokes equations, based on a continuum formulation for the sediment concentration, to investigate the physics of turbidity currents in complex situations, such as when they interact ...

Three-Dimensional Numerical Modeling of Confined and Unconfined Turbidity Currents – Model Development and Validation [PDF]

Port Said Engineering Research Journal
Turbidity currents are sediment-laden gravity currents that transfer sediments to deep sea and lake floors through erosion and deposition. These deposits form subaqueous fans in deep marine environments and can reduce reservoir storage capacity ...

Inadequacy of fluvial energetics for describing gravity current autosuspension

Nature Communications, 2023
Gravity currents, such as sediment-laden turbidity currents, are ubiquitous natural flows that are driven by a density difference. Turbidity currents have provided vital motivation to advance understanding of this class of flows because their enigmatic ...

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

Bottom Current Modification of Turbidite Lobe Complexes

Frontiers in Earth Science, 2022
Submarine lobes form at the distal end of sediment gravity flow systems and are globally important sinks for sediment, anthropogenic pollutants and organic carbon, as well as forming hydrocarbon and CO2 reservoirs.
