Study
- Citation
- Valtanen, M., Sillanpää, N., & Setälä, H. (2014). The Effects of Urbanization on Runoff Pollutant Concentrations, Loadings and Their Seasonal Patterns Under Cold Climate. Water, Air, & Soil Pollution.
- Study description
- This study examined the effects of different land use types and imperviousness on storm water runoff pollutant loads.
Response
- Cause term/trajectory
-
Surface runoff - impervious surfaces
(Increase)
- Cause description
- Impervious surfaces. 3 catchments were assessed with differing imperviousness - Low: 19%, Intermediate: 62%, High: 89%
- Effect term/trajectory
-
Water quality - organic matter
- Effect description
- No correlation between imperviousness and total organic carbon was identified with lowest concentration of TOC identified in the intermediate catchment and highest in the High catchment.
- Response measure type
- Spearman correlation coefficient
