 If the current infiltration rate is greater than a threshold (//​mactrinf//,​ mm/​timestep) then macropore flow (//​macroflow//​) and surface runoff (//​infoverflow//​) may occur. In addition, the water in the upper soil layer needs to be larger than another threshold (//​mactrsm//​) for surface runoff and macropore flow to occur.
