Flow Behavior of Ponded Turbidity Currents [PDF]
Journal of Sedimentary Research, 2015 Abstract: 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 recognized in slope mini-basins and on

Geosystems and Geoenvironment, 2023 Turbidity currents are important ocean dynamic processes that influence sediment transport, ocean engineering, and marine environments. As a turbidity current evolves, its macroscopic and mesoscopic properties are controlled by ambient fluid mechanisms ...

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 JournalTurbidity 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 ...

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 ...

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 ...

Turbidity Current Bedforms [PDF]
, 2016 Turbidity currents in the submarine seascape are what river flows are in terrestrial landscapes. While rivers transport sediment from the mountains through valleys towards the sea, turbidity currents transport sediment from the shallow marine realms through canyons towards the deeper abyssal plains.

A 3D Numerical Model for Turbidity Currents
WSEAS TRANSACTIONS ON FLUID MECHANICS, 2020 A numerical model that solves two-phase flow motion equations to reproduce turbidity currents that occur in reservoirs, is proposed. Three formalizations of the two-phase flow motion equations are presented: the first one can be adopted for high concentration values; the second one is valid under the hypothesis of diluted concentrations; the third one ...
