How to Tell how Long Normal Flow is used in a Link in #InfoSWMM, H2OMap SWMM w/ #SWMM5

How to Tell how Long Normal Flow is used in a Link in #InfoSWMM, H2OMap SWMM w/ #SWMM5

Find the Fraction of Normal Flow Limited in the Flow Classification Table and copy it to the Link Information Table - the value of FLM can then be Displayed in a Map using the Map Display command. In this small example, three links primarily used normal flow and one uses it for a short time. Normal flow only uses the Manning's equation and the link upstream depth, hydraulic radius and cross sectional area to compute the flow.

St. Venant equation solution – this is the link attribute data used when the St. Venant Equation is used in #SWMM 5. Simulated Parameters from the upstream, midpoint and downstream sections of the link are used.

Normal Flow Equation – this is the link attribute data used when the Normal Flow Equation is used in #SWMM 5. Only simulated parameters from the upstream end of the link are used if the normal flow equation is used for the time step.

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

· November 14, 2015

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:

Horton

Modified Horton

Green Ampt

Modified Green Ampt

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).

: Figure 3. A key to getting good infiltration results is defining the infiltration parameters in the Soil DB Table.

: Figure 4. You can also define both your Soil parameters and Soil Coverage for each Subcatchment in the Attribute Browser.
