I am working on a project which is related to the three dimensional scouring under submarine pipeline and I am using OpenFOAM to simulate the flow and scouring. I am using RAS and LES model to simulate the ocean flow. Now problem is I don't know how to make a geometry for bed formation under pipeline and how to simulate the scouring under that pipeline. I can simulate RAS and LES flow using openFOAM but cannot do anything with the scouring. I found a solver named 'sediFoam' but still don't know much more about it and how to operate it. Is there any other solver which will be useful for my case? I am urgently requesting to help me out. Thanks.

You can check attached picture to understand my geometry.
