- Study description
- The hydrology and water quality of a bioretention basin was modelled to assess the effectiveness of these systems at reducing peak flows and pollutant loads. The study found that peak flows and concentrations of TSS, TP and TN during rain events were lowered by the bioretention basin studied.
