This paper discusses the outcomes of a research project which involved in-depth investigation of stormwater quality by analysing rainfall-runoff and water quality data from four urban residential catchments. The outcomes of the investigations confirmed that the pollutant export characteristics from these catchments are strongly correlates with the rainfall intensity rather than other rainfall-runoff parameter. Further, the overall pollutant export from the catchment is mostly dependent on lesser number of high intensity storm events. These findings suggested that the rainfall intensity would be the most suitable rainfall-runoff parameter for pollutant export equations in stormwater quality models. Furthermore, the variation of stormwater quality with range of rainfall-runoff parameters emphasis the necessity of long term calibration of models.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
