Time-series sediment acoustics and LISST-ABS testing

Acoustics and other surrogates can be used to accurately and cost-effectively provide time-series estimates of suspended-sediment concentration and load, which is essential for creating informed solutions to many sediment-related environmental, engineering, and agricultural concerns. Interagency efforts in recent years have advanced the testing, methods development, operational guidelines, and training on sediment acoustics. This extended abstract provides an update on horizontal profiling methodologies and introduces the testing of the LISST-ABS (Acoustic Backscatter Sensor).
