Spatial and temporal modelling of heavy metal contaminant loadings to urban streams

Abstract

Urban stormwater contains substantial amounts of heavy metals (Zn, Cu, Pb) and suspended solids (TSS). Untreated, these contaminants are recognized as the main detriment to urban waterways. To quantify the sources of these pollutants in urban catchments and resulting discharges to specific points along waterways, the MEDUSA (Modelled Estimates of Discharges for Urban Stormwater Assessments) modelling framework was developed.
