Study
- Citation
- Liu, Y., Wang, C., Yu, Y., Chen, Y., Du, L., Qu, X., Peng, W., Zhang, M., & Gui, C. (2019). Effect of Urban Stormwater Road Runoff of Different Land Use Types on an Urban River in Shenzhen, China. Water.
- Study description
- Urban runoff from three different locations classified as an arterial road, residential road and industrial area was collected during rainfall events. The study collected runoff at the roads during 5 rainfall events and analysed the water quality through time to assess the pollutant concentrations and decreasing of pollutants during the runoff event.
Response
- Cause term/trajectory
-
Hydrology - surface flow (volume)
(Increase)
- Effect term/trajectory
-
Water quality - nutrients (other)
(Increase)
- Effect description
- A first flush effect was observed for most pollutants studied (TP, NH4, TSS, COD) during heavy rainfall recorded in this study. No first flush was observed during the lighter rainfall recorded in the study. Study concludes that the rainfall intensity was an important factor in pollutant wash off.
