Subject:   How  Does   Green   Ampt   Cumulative   Event   Infiltration   work  in  SWMM   5 ? This graph shows the values of the internal  SWMM   5  parameters for  Green   Ampt   Infiltration  for the pervious area of a Subcatchment during a simulation.  The parameters are: ·          F or FTOT which is the  cumulative   event   infiltration  at the start of a time interval in the internal units of feet in  SWMM   5 , ·          FU or current moisture content of the upper zone of the of the soil ·          FUMAX which is the saturated moisture content of the upper zone in feet and stays constant during the simulation   Figure 1.   How FTOT, FU and F change over time Figure 2.   A closer look at how FTOT or F a...
