From January 2016 until February 2018, the USGS evaluated Sequoia’s LISST-ABS at 10 streamflow-gaging stations, collecting LISST-ABS and suspended sediment concentration (SSC) data. The evaluation also compared the LISST-ABS to standard turbidity sensors normally used by the USGS. Recently, the results were presented in a report that found “Using the LISST-ABS as a surrogate for measuring SSC in a dynamic fluvial system shows promise given the results of the ABS concentration and SSC correlation coefficients at the 10 stations tested using factory-calibrated instruments.”
