Study
- Citation
- Hou, L., & Zhang, X. (2013). Comparing urban runoff quality of a felt roof and an asphalt road in Beijing. Hydrology Research.
- Study description
- This study looked at the runoff quality from a roof and asphalt surface. The study also investigated correlations between nutrients and suspended solids in runoff.
Response
- Cause term/trajectory
-
Water quality - nutrients (phosphorus)
(Increase)
- Cause description
- Total phosphorus (TP)
- Effect term/trajectory
-
Water quality - oxygen
(Increase)
- Effect description
- Chemical Oxygen Demand (CODcr)
- Response measure type
- R-squared - simple linear
- Response measure description
- Regression showed a strong correlation between TP and CODcr for road runoff- R squared determination coefficients for 4 runoff events (0.9523, 0.9358, 0.9231, 0.834)
