How Does Green Ampt Cumulative Event Infiltration work in SWMM 5?
Subject: How Does Green Ampt Cumulative
This graph shows the values of the internal SWMM 5 parameters for Green Ampt Infiltration
· F or FTOT which is the cumulative event infiltrat
· 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 and FU Change over time in a Green Ampt Pervious Area Simulation.
