Field data for evaluation of the LISST-SL2, an in-stream particle-size analyzer, at selected rivers in Washington and Virginia, 2018-20

Measurements of suspended-sediment concentration and particle-size distribution were made in selected rivers located in Washington and Virginia with an in-stream, particle-size analyzer that uses laser-diffraction methods to measure the concentration and size of suspended particles. Measurements were made in 11 rivers from 2018 to 2019 using the LIST-SL2, a second-generation streamlined sensor that is part of the Laser In Situ Scattering and Transmissometry (LISST) series of instruments manufactured by Sequoia Science Inc.
