How is the Soil Saturated Conductivity Used in SWMM 5 Green-Ampt? by dickinsonre 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 Green-Ampt Infiltration in SWMM 5 Figure 2.  The sensitivity of the total infiltration loss to the soil saturated conductivity in a continuous simulation via Blogger http://www.swmm5.net/2013/08/how-is-soil-saturated-conductivity-used.html
