5203 |a"Tests were conducted in the towing tank at NWRI on the DH-59 sediment sampler with carefully selected nozzles. Statistical analysis of the test data were conducted. It has been shown that individual samplers can be calibrated with a high degree of repeatability but that the variability of calibrations from sampler to sampler was quite high at the lower velocities. It was further shown that the performance of the sampler was sensitive to changes in the velocity coefficient of the 3.2 mm nozzle. Similar variabilities in the velocity coefficient for the 4.8 mm and 6.4 mm nozzles did not affect the performance of the sampler. Similar tests on other types of samplers are proceeding"--Abstract.
