| Abstract: | Suspended-sediment samplers must sample isokinetically (at stream velocity) in order to collect representative water samples of rivers. Each sampler sold by the Federal Interagency Sedimentation Project has been adjusted to sample isokinetically and tested in a flume to verify the calibration. The test program for a modified U.S. P-61 sampler provided an opportunity to compare flume and towing tank tests. Although the two tests yielded statistically distinct results, the difference between them was quite small. The lack of turbulence in the towing test probably accounts for the slight disparity between the two relations. The conclusion is that verifying the calibration of any suspended-sediment sampler by either the flume or towing method should give acceptable results. (Author ‘s abstract) |
