SUSPEND LOAD CALCULATIONS MADE FROM CALIBRATING ADCP VELOCITY AND BACKSCATTER MEASUREMENTS

Sediment transport surveys along the Mississippi River try determine the integrated transport of water and sediments in the main stem of the river and through controlled/non controlled diversions. The goal of the integrated surveys is to achieve an understanding of the suspended and bed-load transport of sand and fines (silt and clay) Integrated surveys are needed to ground-truth 1D and multidimensional modeling efforts to determine the extent to which the diversion is influencing shoaling in adjacent navigation channels and to determine sediment fluxes into the receiving basins. The results of these types of surveys and techniques will be presented to show the value of these methods and technologies. Calibrating the ADCP, Acoustic Doppler Current Profiler, currents and acoustic backscatter into an integrated measurement has enormous scientific value for design and system management. The techniques of collection, calibration and analysis will be presented.
