| 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. The two flows are calculated as a percentage (//macrate// respective //srrate//) of the infiltration above the first threshold; | If the current infiltration rate is greater than a threshold (//mactrinf//, mm/timestep) then macropore flow (//macroflow//) and surface runoff (//infoverflow//) may occur.
