How to Use an IDF Curve with the Rational Method in InfoSWMM

The IDF Table or Curve is intended to only work with the Rational Method Hydrology:

  1. You make a Curve called Reserved
  2. The X column is time in Minutes
  3. The Y column is either Intensity in inches/hour or millimeters per hour
  4. If you use the Modified Rational Method the IDF Curve

How to Use Population for DWF in SWMM5 and InfoSWMM

The SWMM5 engine uses mean flow as the dry weather flow value (DWF) and not population but does allow weekday, weekend, daily and monthly patterns. You can use these many pattern options to actually use population in the SWMM5 and InfoSWMM dry weather flow tables. Here are the steps as Read the rest
