This study aims to quantify major sources of nitrogen (N) and phosphorus (P) entering urban residential catchments on two of the major dunal systems. The export of N and P from these catchments in stormwater discharge was measured, allowing investigation of some of the key pathways through which N and P enter the drainage network from the catchment. This information was then used to recommend catchment management approaches to reduce nutrient discharge into stormwater.
