New - Five Infiltration Options Now in InfoSWMM v14 and H2OMap SWMM v14 for Watershed Modeling

Infiltration from the pervious area is a marvelous and from a runoff volume and runoff peak perspective a vital process in modeling the hydrology and ultimately the hydraulics of your Watersheds.  Figure 1 shows the five options available in InfoSWMM and H2OMap SWMM after the version 14 update which was based on the EPA SWMM 5.1.010 release:
Storm cloud Horton
Storm cloud Modified Horton
Storm cloud Green Ampt
Storm cloud Modified Green Ampt
Storm cloud Curve Number
Not only can you have a different Infiltration option per Model Simulation but you can have different options for each scenario and even for individual Subcatchments in a Scenario (Figure 2).  In #InfoSWMM and H2OMap SWMM the Soil DB table (Figure 3) shows the individual parameters that apply to Horton, Green Ampt and Curve Number infiltration. The Modified Horton and Green Ampt have the same parameters as the Horton and Green Ampt Soil Types.  The Soil Coverage is specified in the Subcatchment DB Table or individually in the Subcatchment Attribute Browser (AB) as shown in Figure 4.  You can also see the infiltration losses for either multiple Subcatchments or for one Subcatchment across many scenarios using the Advanced Reference Graphics Analysis in Innovyze’s InfoSWMM and H2OMap SWMM (Figure 5).
