<br><br>
The talk will discuss high-resolution, two- and three-dimensional Navier-Stokes<br>
simulations of sediment transport processes, along with related linear instability<br>
mechanisms, that have advanced our understanding of turbidity currents, and of the<br>
mechanisms by which they are able to generate channels, levees and sediment waves.<br>
For large-scale simulations, the mathematical description assumes that the<br>
particles have negligible inertia and are much smaller than the smallest length<br>
scales of the buoyancy-induced fluid motion. Under these conditions, we can employ<br>
an Eulerian approach for the description of the particulate phase. Results will be<br>
shown regarding the unsteady interaction of turbidity currents with channels,<br>
pipelines and local seamounts. We will also address currents in stratified ambient,<br>
as well as reversing buoyancy currents. Furthermore, particle-resolving simulations<br>
will be discussed with the goal of enhancing our understanding of the mechanisms<br>
governing erosion.<span class="HOEnZb"><font color="#888888"><span><br>
