Presentation Description
Acoustic backscatter as a surrogate for suspended sediment concentration using Sediment Transport Analysis, Mississippi River at Belle Chasse, LAA sediment rating curve was developed by pairing sediment concentration and velocity profile data collected from the USGS Belle Chasse monitoring site and will provide CPRA with sediment transport estimates that will help inform operational decisions. A USGS priority Sediment Transport Analysis (STA) MATLAB program assists with analyzing Acoustic Doppler Current Profiler data collected at the time of sediment collection as a surrogate for SSC. The STA results from the 2018 flood year from the lower Mississippi River indicated that both sand and total models yielded similar results. Sand models were successful during high flow events and ranged from about R2 = 0.53 in highest flow (1.25M cubic feet per second (cfs) to about R2 = 0.63 in moderately high flows (960Kcfs) and no relationships could be established for sand or total models for streamflow below about 750Kcfs due to the lack of sufficient sand concentrations in the water column.
