摘要: Urban/rural stormwater quantity modelling has been well-researched and achieved sufficient accuracy benchmark. However, runoff quality (i.e. pollutants transport associated with stormwater) are relatively difficult largely depends on catchment characteristics/land-uses; these can be estimated acceptable provided equations established through extensive field measurements. To ensure ecologically sustainable development, several treatment systems have proposed. Model of Urban Stormwater Improvement Conceptualisation (MUSIC) developed widely used in Australia, estimates pollutant from catchments different systems. This paper presents a study the MUSIC estimations for options Australia abroad. Data measurements constructed (bioretention, grass swale porus pavement) Sweden, New Zealand Scotland was collected literatures. The experimental results were compared MUSIC's under similar conditions. In general, it found that simulate flow conditions good accuracy, however predictions removal efficiencies Total Suspended Solids (TSS), Phosphorus (TP) Nitrogen (TN) varying. Potential reasons discrepancies discussed. Also, summary table showing overall capability simulating measures presented.
