Description :
In this study, sample weights collected by 3 types of pressure-difference samplers are compared to determine whether differences are statistically significant. The implication of the results is that measured transport rates will vary depending on the sampler used and, therefore, they are not directly comparable without some mode of calibration. To place this finding in a larger context, sediment rating curves, determined from weights of samples and measurements of flow, were integrated over available flow records and used to estimate annual yield. Discussion of the results.
