| Summary: | <p>Sediment transport measurements are determined using techniques such as bedmaterial
and suspended-sediment sampling, and more recently the conversion of acoustic
backscatter (ABS). Acoustic waves scatter and attenuate while passing through a watersediment
mixture and the backscatter is converted to sediment concentration, size, and
shape. A multiple case study performed using data from West Bay, Old River, and
Mississippi River at Vicksburg show the variability of a large river system TSM flux
during assorted hydrographs and two methods (CHL and moving boat) capture the
events. After processing and applying the two methods the results showed that the
methods are typically within 8% to 41% of each other when computing sediment flux.
The conversion of total suspended material (TSM) from ABS was an average of 0.2% to
69% from the sample TSM. Peak part of the hydrograph had the highest average
suspended sediment concentration (SSC) and descending had the lowest average SSC.</p>
