Describe the proposed research in about 200 words. Determination of critical conditions for the initial motion of uniform sediments is of considerable interest to river engineers and geomorphologists. A commonly used method for determining the threshold of motion of such sediments is the Shields threshold curve. However, it is well known that there is considerable scatter in the data underpinning this method. A number of attempts have been made to improve the curve, but none of these have significantly reduced the uncertainty associated with the technique. In most other areas of engineeing such uncertainty would be considered unacceptable for practical use.This application has been prompted by the findings of a recent preliminary research study by the named RA. The study findings suggest that by reworking some of the ideas contained in the extensive research literature on a large data set (collected with the benefit of modern data collection techniques) it will be possible to reduce the uncertainty in the application of Shields threshold curve. Achieving this will be a major breakthrough in a problem that has engaged the hydraulics research community since Rouse first published the Shields curve in 1939.
