Description:

The publication presents the results of an analysis concerning the impact of the method of an effective impervious area (EIA) mapping in the simulation model on the runoff from urban catchment. The runoff volumes and flood volumes generated by heavy rainfall, causing the runoff from pervious area, were compared. Two EIA mapping variants were taken into account – first one, concerning reduction in imperviousness degree and, second one, directing the runoff from impervious to pervious area. The runoff calculations were made on basis of simulation results in SWMM5. For building the catchment model data of existing catchment with the area of nearly 80 hectares in Bydgoszcz was used. The value of the EIA was estimated on the basis of empirical formulas. The reduction in impervious area connected directly to the storm water sewer system from 40% to 10% of the total impervious area were considered. It has been shown that using the reduction in imperviousness degree for EIA mapping can lead to underestimation of runoff volume. The difference in runoff calculated for analyzed EIA mapping variants increases with the decrease in infiltration capacity of pervious area and is in large part transformed into a flood volume.
