Settling of cohesive sediment: particle-resolved simulations

LTFATE Cohesive Sediment Transport Model

hydrodynamics and sediment transport model used to determine the longand short-term stability of dredged material mounds. This technical note (TN) introduces a new cohesive sediment transport submodel for LTFATE, which includes a combined current-wave shear stress calculation and a layered sediment bed model. LTFATE can be accessed via the Internet at the following address: http://www.wes.army....

Image Processing Methods for in Situ Estimation of Cohesive Sediment Floc Size, Settling Velocity, and Density 2

Size and settling velocities of cohesive flocs and suspended sediment aggregates in a trailing suction hopper dredge plume

A field experiment was conducted to quantify settling velocities, aggregate states, and flocculation within a hopper dredge plume. Particular interest was in determining the abundance of dense, bed aggregates suspended from the consolidated bed during dredging. A suspended sediment plume from the hopper dredge Essayons was sampled for a period of 90 min after dredging. Settling velocities and s...

Field Measurement of Particle Settling Velocity

Many stormwater management practices depend on sedimentation as their primary removal mechanism, but the settling velocity distribution of particles in runoff from a specific watershed is rarely known. A simple and effective method to characterize settling velocity distribution is needed to improve the design of stormwater management practices. Elutriation devices have been used to characterize...
