Urban stormwater runoff is a major source of pollutant constituents within water bodies. The importance of phosphorus in accelerating eutrophication of water bodies has been well documented. Knowledge of processes and mechanisms influencing the motion of phospohorus in urban catchments, however, is still poor. To increase our understanding of these processes, it is necessary to study the mechanisms through which alternative forms of phosphorus are moved in urban catchments. There is a need to investigate the characteristic of the nutrient load from urban catchments in greater detail. An investigation into the characteristic of phosphorus transported from the Musgrave Avenue Catchment in Sydney, New South Wales has been conducted. Presented in this paper is a discussion of the different forms of phosphorus and methods by which their movement in urban catchments may be simulated. Of particular interest is the relationship developed between particulate surface area and total phosphorus. The investigation of the pollutant characteristics and its relationship with suspended sediment will enable the performance of sedimentation basins and wetlands to be predicted.
