Includes bibliographical references (pages 13-14). "Using dimensional analysis and experiments conducted in a rectangular flume, a bed-load discharge coefficient was developed. The coefficient was found to depend on bed-form steepness and relative sand grain size. The results showed that the bed-load coefficient is affected significantly by sand grain size only when the dunes are flat. When dunes are steep, the value of the bed-load coefficient is affected mainly by the dune steepness. Application of the bed-load coefficient resulted in some improvement of estimating bed load"--Summary. Includes abstracts in English and French. Bed load Mathematical models. Sand dunes Measurement.
