*Computational Sediment Transport: High-Resolution Models*

Eckart Meiburg, UC Santa Barbara, EEUU


The talk will discuss high-resolution, two- and three-dimensional
Navier-Stokes
simulations of sediment transport processes, along with related linear
instability
mechanisms, that have advanced our understanding of turbidity currents, and
of the
mechanisms by which they are able to generate channels, levees and sediment
waves.
For large-scale simulations, the mathematical description assumes that the
particles have negligible inertia and are much smaller than the smallest
length
scales of the buoyancy-induced fluid motion. Under these conditions, we can
employ
an Eulerian approach for the description of the particulate phase. Results
will be
shown regarding the unsteady interaction of turbidity currents with
channels,
pipelines and local seamounts. We will also address currents in stratified
ambient,
as well as reversing buoyancy currents. Furthermore, particle-resolving
simulations
will be discussed with the goal of enhancing our understanding of the
mechanisms
governing erosion.
