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.
