SWMM - Dry weather Inflows with Pollutants

Dry Weather inflows specify continuous sources of dry weather flow entering a node. the drainage system and which contains pollutants. These tributaries are calculated by the expression:

Influx = (Average Value) * (Pattern 1) * (Pattern 2) * (Pattern 3) * (Pattern 4)

Where:

Average Value - Specifies the average (or baseline) value of dry weather influx
Pattern 1 - time pattern name
Pattern 2 - time pattern name
Pattern 3 - time pattern name
Pattern 4 - time pattern name

If any time pattern is not specified, its factor will take effect. 1.0

You can specify data for each pollutant in the project:

In the left frame, mark the pollutant of the project and in the right frame, specify the average value with the specified units indicated in the field "Measurement of the Pollutant"
