Question Wind simulation - ground boundary conditions

rmz is on a distinguished road

I am working on a simulation of wind on buildings, I checked the similar tutorial cases of openFoam and constructed my model accordingly.

I'm not sure of the boundary conditions for the ground (type: wall).
-I am applying atmospheric boundary layer (ABL) in my simulations.
-fields: U, p, epsilon, nut, k

my question is: which boundary conditions should I use for (epsilon, nut and k) on the patch ground?

Thank you
