URBAN RUNOFF POLLUTION DERIVED FROM LONG-TIME SIMULATION

Urban stormwater runoff pollution is determined by randomly distributed processes. Thus meaningful and realistic conclusions concerning urban runoff pollution may not be derived from the simulation of singular rainstrom events. The method presented allows for continuous simulation of several pollutants. Runoff and its pollution from catchment areas, characterized as residential, commercial, industrial or mixed areas, are calculated by an unit hydrograph method, modified for the calculation of water quality. Flow routing through the network is based on the dynamic wave equations. Statistical analysis of the results provides annual and monthly frequency and duration curves for flows and pollutants at any node of the network. Still, single event simulation is possible providing pollutographs and hydrographs at any node of the network. First verification tests of the model produced satisfactory results.
