Sediment Acoustics

Continuous Time-Series Methods

Suspended sediment characteristics relate functionally to acoustic backscatter and attenuation. Continuous time-series suspended-sediment concentration (SSC) is obtained using continuous time-series acoustic metrics from fixed-place, in situ acoustic Doppler velocity meter (ADVM) data and a calibrated and approved acoustic-SSC index rating. These sections describe and utilize analytical methods to normalize measured acoustic backscatter data for several factors to isolate the attenuation and backscatter that is driven by sediment characteristics
