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 - suspended material/sediment (Increase)
Cause description
Total suspended sediment (TSS)
Effect term/trajectory
Water quality - nutrients (nitrogen) (Increase)
Effect description
Total nitrogen (TN)
Response measure type
R-squared - simple linear
Response measure description
Regression showed a positive correlation between TN and TSS in road runoff - R squared determination coefficients for 4 road runoff events (0.9644, 0.9731, 0.6338, 0.7512)
