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.
