ResultsMulti-frequency acoustics, laser diffraction, turbidityTesting since 2007

Acoustics – best surrogate technology

1.5 to 3MHz generally work best

R

2 ranges 0.87 to 0.93 Total, fine, and coarse fractionsLISST: R2 = 0.62 (when working)

Turbidity: R2 = 0.65 – 0.92Improvement over traditional transport curves
