Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references (pages 10-11). "Existing data were reviewed to compare the hydraulic and sampling efficiency of the WSC basket type bedload sampler. Using dimensional analysis, a link between the hydraulic efficiency and the sampling efficiency was developed. Results show the relative reduction in the hydraulic and sampling efficiency as sediment accumulates in the sampler. Observations regarding the importance of the hydraulic efficiency in improving the sampling efficiency are made"--Summary, page iii.
