Includes bibliographical references. "An experimental study in a sediment flume was conducted to examine the usefulness of computing bed-load using bed-form height and speed obtained from sequences of profiles of the mobile bed taken a known length of time apart. A theoretical analysis was made to obtain a general bed-load equation for this purpose. This analysis showed that a coefficient was required to jointly take into account the geometry of the bed-form and that portion of the bed-form which contributes to bed-load transport. Dimensional analysis indicated that the coefficient should vary with flow conditions. Examination of published data, showed that such a coefficient varies strongly with mobility number and appears to be independent of depth for cases of practical interest"--Summary, page iii.
