-!--    Lateral boundary conditions at the inflow. Quasi Neumann conditions
-!--    are needed for the wall normal velocity in order to ensure zero
-!--    divergence. Dirichlet conditions are used for all other quantities.
+!--    In case of inflow at the south boundary the boundary for v is at nys
+!--    and in case of inflow at the left boundary the boundary for u is at nxl.
+!--    Since in prognostic_equations (cache optimized version) these levels are
+!--    handled as a prognostic level, boundary values have to be restored here.
