The relationship between the rainfall, total losses from the previous area, evaporation and infiltration only rate for SWMM 5

Subject:  The relationship between the rainfalltotal losses from the previous areaevaporation and infiltration only rate.

 

The total loss from a subcatchment pervious area is the sum of the evaporation + infiltration loss.  Typically the evaporation rate is much less than the infiltration rateSWMM 5 now has too options – evaporation during only dry periods or evaporation during both wet and dry periods.
