Abstract
Nonpoint pollution sources (NPSs) are difficult to manage because their pathways, pollutant load, and runoff characteristics are unclear, unlike point pollution sources. Hence, the Korean government plans to research and develop best management practices (BMPs) for the management of NPSs. The removal efficiency of BMPs varies due to several factors, including rainfall events. These BMPs can be evaluated by numerous methods, and continuous research is being conducted on improving them. In this study, a correlation analysis was conducted to investigate vegetation coverage and retention time as factors affecting the removal efficiency of a vegetative filter strip (VFS), which is a natural nonpoint pollution reduction facility. The results showed that a longer retention time was associated with a higher removal efficiency of a VFS when the vegetation coverage was maintained. Therefore, adequate vegetation coverage and retention time are required to increase the removal efficiency for the VFSs.
