Investigation of turbidity and suspended solids behavior in storm water run-off from different land-use sites in South Korea

Turbidity is known to be the quickest and cost effective characteristic to evaluate the eroded sediment amount in urban and construction sites run-off. In Korea, the focus towards the storm water run-off from the construction site is limited and therefore, this research investigates storm water run-...

Description
Summary:Turbidity is known to be the quickest and cost effective characteristic to evaluate the eroded sediment amount in urban and construction sites run-off. In Korea, the focus towards the storm water run-off from the construction site is limited and therefore, this research investigates storm water run-off pollution effects and quantifies the turbidity–suspended solids relationship from various land-use areas including the construction site in Yongin watershed Korea. In this study, precipitation, discharge, and water quality data were collected and analyzed between June 2011 and December 2012. It was found that the construction site showed high turbidity concentration levels in all storm water events compared to other monitoring sites. Overall mean turbidity level in the construction site was 4, 27, and 70 times higher than mix catchment, agriculture, and urban sites, whereas, mean turbidity level in mix catchment site was 17 times higher than urban site, therefore, hydro–pollutograph can be described in clear flow and turbid flow period portions. Results obtained in this study showed a strong correlation between suspended particles and turbidity specifically in the construction site compared to other monitoring sites. These findings will support managers to plan, manage, and monitor storm water pollution according to specific land-use type.
