SWMM Surface Runoff and Storage difference in RPT and OUT file
Raw
readme.md

I have two models, the first model has one subcatchment and second has two subcatchments. The sum of impervious, pervious and impervious areas are equal for both models. I add an 10 mm constant rainfall with a duration of 1 hour.
The infiltration rate is set to 10 mm/h.
The storage for impervious areas is 5 mm.
The evaporation rate is set to 0 mm/day.
The sum of subcatchment areas is 100 ha with 50% impervious and 50% impervious with no storage.
This should result in 10.000 m³ rainfall, 5000 m³ infiltration loss, 1250 m³ stored volume in the impervious areas and 3750 m³ runoff.
