P073: Fine Particle Capture by Synthetic Vegetation in a Laboratory Flume

This project focuses on the measurement of fine particle capture efficiencies in a laboratory flume using analogs of the vegetation present in an SEZ. The laboratory flume offers the ability to vary flow rate, substrate density, stem width, particle concentration, and presence/absence of biofilms in a repeatable fashion and to measure the changing particle size distribution and particle concentration over time. The size-specific removal efficiencies that can be calculated in this way can then be used as the basis for assigning removal efficiencies in any SEZ in the LTB, based on site-specific flowrate, vegetation type and density, and initial particle concentration.
