Sediment Collection and Analysis of Sediment Contributing to State Storm Sewer Facilities

NDOT would like to implement SAFL Baffles and possibly other mechanical sediment trapping devices in future projects to address MS4 regulations. These devices require preliminary determination of runoff sediment characteristics including particle size distributions and concentrations. The required data are available in some other states but not in Nebraska. Using data obtained in other states will be inaccurate and will likely result in over- or under-design of the sediment trapping devices. Proper design of the trapping devices will optimize cost and efficiency of the devices. Measuring sediment size distributions and concentrations at multiple drainage sites in Nebraska municipalities is needed to provide defensible characterization of runoff sediment. Modeling of the sediment size distributions and concentrations is needed to extend measured results to similar drainages.
