Sediment transport and deposition
 

Hi,
I am using Fluent and want to simulate cases of sediment movement, erosion and deposition in open channel flows. These situation arise when there is bank/bed erosion and deposition in alluvial channels, deposition of incoming sediment or bridge pier scouring etc. What strategy should I adopt? Which model should I use? Can anyone has some example of such cases especially for open channels.
Thanks
