Surface Runoff

If the precipitation rate (inches per hour) exceeds the infiltration rate of the soil we receive no benefit from the precipitation as it becomes surface runoff to retention ponds and storm sewers.

Virtual Rain Sensor looks at the peak inches per hour in a given day and uses the soil type for each zone to determine the maximum infiltration rate.  If there is more than one significant storm or an extended period of heavy rainfall this value may be inaccurate.
