Study
- Citation
- Vaze, J., & Chiew, F. H. S. (2003). Study of pollutant washoff from small impervious experimental plots. Water Resources Research.
- Study description
- This study examined the impact of rainfall and runoff on pollutant washoff in both field and laboratory experiments. The study looked at the washoff characteristics of TSS, TN and TP.

- Effect description
- The energy from rainfall was shown to have an effect on pollutant loads in runoff, attributed to the energy in rainfall causing pollutants to be dislodged from the surface. The experiment compared a surface affected by rainfall and runoff with a surface only affected by runoff and found rainfall to have a notable impact on the pollutant wash-off loads. Note that no statistical result was stated in the paper to evaluate this relationship or determine effect size/significance.
