Modelling source area contributions of stormwater pollutants with Storm Water Management Model (SWMM)

Research output: Chapter in Book/Report/Conference proceedingConference article in proceedingsProfessional


The source area contributions of total suspended solids, total phosphorus and total nitrogen were simulated with SWMM using event mean concentrations (EMCs) from literature for different surface types. Simulated loads were compared against measured loads at the catchment outlet in a residential catchment in Espoo, Finland. A high variability in the modeled loads was observed depending on the EMC data source. Simulated loads were usually much higher than the measured loads. This can be explained by lack of local data for sources area EMCs and by the fact that SWMM does not take into account the mechanisms affecting loads along the pollutant pathways from catchment to sewer outlet.
