M.S. Yalin's contribution to bedload transport in rivers: 46 years of hindsight

Research output: Contribution to journalArticlepeer-review

Abstract

The enduring legacy of the Yalin equation of bedload transport is evaluated. The derivation of the equation in-cludes three innovative aspects: (i) a rigorous use of dimensional analysis to simplify the formulation; (ii) a consideration of the randomness of grain placement rather than turbulence, resulting in a definable threshold of motion; and (iii) the in-troduction of a physically based, dynamic model of grain saltation into a bedload transport theory. The original relation re-mains useful today. In addition, the treatment of saltation has inspired an innovative line of research that continues to evolve today.
