How to Model and Display Peaking Factors in InfoSWMM
How to Model and Display Peaking Factors in InfoSWMM A significant difference between InfoSewer/H2OMap Sewer and InfoSWMM/H2OMap SWMM is how peaking factors are applied to the dry weather flow (DWF) at the nodes. InfoSewer has unspeakable and peakable flow with the peakable flow equation defined in the peaking tab of the Run Manger (Figure 1). The peakable flow equation is only used in the Steady State solution of InfoSewer. InfoSWMM only has unspeakable flow and no way to define peakable flow. This blog shows a way to externally calculate the peakable flow in Excel and apply it as a DWF Scenario DB in InfoSWMM/H2OMap SWMM. Here is a list of steps you can take to show the peakable load in InfoSWMM/H2OMap SWMM. Figure 12 contrasts the peakable flow estimate in InfoSWMM compared to the InfoSewer peakable steady state flows. Step 1 . Enter the DWF Unpeakable flow in the InfoSWMM DWF DB table without a DWF Pattern (Figure 2). We will...
