Transfering surface boundary slope value to the entire subsurface domain

Please login with a confirmed email address before reporting spam

I'm working with a 2D groundwater model. In order to match the initial groundwater head with the topography, I need to transfer the slope calculated at the surface boundary geometry (defined as variable at surface boundary, please see the attached image) to the entire subsurface domain.

Is it possible to do this with the coupling definition?
(I'm not familiar with the coupling application)

Thank you very much for your input.
