Keynote Presentation: Connecting Particle Size Distribution with BMP Performance and Surface Water Quality
Presented by Erick McWayne
Stormwater BMP performance for sediment removal is often described statistically by the percent reduction of concentration or load. These methods often do not consider the particle size distribution (PSD) of the suspended sediment. The ability of BMPs to reduce suspended sediment concentration is directly related to the PSD. Additionally, the sorbed contaminant load on the suspended sediment is directly related to PSD. In this presentation we will explore how PSD affects the transport and fate of suspended sediment and sorbed contaminants (e.g., metals), and how PSD impacts BMP performance and surface water quality.
