Reply To: Three-phase Simulation: Eulerian Model for Free-Surface Flow around Bridge Pier

Yes, with caveats. Note, I'm also limited to what's in the manuals and that is "public" knowledge. I did do this some years ago to prove a point, and have practical experience with scour pits around ship wrecks. 

The water and free surface part are relatively simple, but mesh resolution may be something you need to check relative to compute & time availability. 

The sediment is a different problem. In the Eulerian model you'd need different phases for each particle size. Additionally the model assumes a "mobile" solid, so saltation and compaction aren't considered. For a river you also have silt/material carried from upstream that may fill in a scour pit.
