Subject:    How is the  Soil   Saturated   Conductivity   Used  in  SWMM   5   Green - Ampt ? How sensitive is the infiltration loss and rate to the  Soil   Saturated   Conductivity  parameter in the  SWMM   5   Green - Ampt   infiltration method.   Figure 2 shows how the total infiltration loss and total loss rate vary as you change the  soil   saturated   conductivity  from 1 to 0.1 to 0.01 inches/hour.  Internally, Ks is  used  to check saturation and in the computation of the  soil  infiltration rate. Two of the checks are: ·          In low rainfall everything infiltrates as irate less than Infil>Ks and ·          In the check to see if the  soil  is already  saturated .     Figure 1.   The three parameters for...
