Total transport was calculated by integrating the model estimated flux profiles. The “acoustically” measured values were compared to values computed from the input concentration and velocity profiles. Trials were made for various free stream velocities using bedload thicknesses of 0.1, 0.3. 0.6, 1.0 and 2.0 cm. When “measuring” combined bedload and suspended load transport, the comparisons show excellent agreement as shown by the blue symbols in Figure 5.. Leslie A. Morrissey UVM. July 25, 2012.
