Diversion structure for the “valabres” water project on the tinee river-france

Abstract

Findings from a 1953 report by A. NIZERY and G. BRAUDEAU are summarized, and reexamined from the present state of knowledge concerning grain sorting. In their comments on the importance and expected effects of grain sorting, these authors appear to have been remarkably ahead of their time. Their execution and interpretation of physical model studies also demonstrates they were aware of the essential role played by the transience of streamflow. They suggested that two flow rates, the limiting discharges for the finest and coarsest material, should characterize the importance of sorting in a given river. We further discuss their findings, and compare them to results from current numerical models.
