Boundary conditions for Scour
 

I created a scour case in sedFoam. i am confused about the BC
in blockmesh The BC for
Inlet -patch
Outlet-Patch
Top-Patch
Front-wall
Front-Wall
Bottom-wall

I tried with cyclic bc for front and back. but now i want to run my case with wall bc for front and back.
Then what are BC should I provide for epsilon, K.b , omega and nut.b of Front, Front, Bottom, Top.
