+Parameter to steer the treatment of the subgrid-scale vertical fluxes within the diffusion terms at k=1 (bottom boundary).\\\\
+By default, the near-surface subgrid-scale fluxes are parameterized (like in the remaining model domain) using the gradient approach. If '''use_surface_fluxes''' = ''.TRUE.,'' the user-assigned surface fluxes are used instead (see [#surface_heatflux surface_heatflux], [#surface_waterflux surface_waterflux] and [#surface_scalarflux surface_scalarflux]) or the surface fluxes are calculated via the Prandtl layer relation (depends on the bottom boundary conditions, see [#bc_pt_b bc_pt_b], [#bc_q_b bc_q_b] and [#bc_s_b bc_s_b]).\\\\
+'''use_surface_fluxes''' is automatically set ''.TRUE.,'' if a Prandtl layer is used (see [#prandtl_layer prandtl_layer]).\\\\
+The user may prescribe the surface fluxes at the bottom boundary without using a Prandtl layer by setting '''use_surface_fluxes''' = ''.T.'' and [#prandtl_layer prandtl_layer] = ''.F.''. If , in this case, the momentum flux (u,,*,,^2^) should also be prescribed, the user must assign an appropriate value within the user-defined code (see [[chapter 3.5]]).

+Currently, no value for the latent heatflux can be assigned. In case of '''use_top_fluxes''' = ''.TRUE.,'' the latent heat flux at the top will be automatically set to zero.

+Parameter to restrict the mixing length in the vicinity of the bottom boundary (and near vertical walls of a non-flat topography).\\\\
+With '''wall_adjustment''' = ''.TRUE.,'' the mixing length is limited to a maximum of  1.8 * z. This condition typically affects only the first grid points above the bottom boundary.\\\\
+In case of  a non-flat topography the respective horizontal distance from vertical walls is used.
