DELAY DISTANCE IN SUSPENDED SEDIMENT TRANSPORT

Masataro Hattori

Abstract


In the previous paper (Hattori, 1969), a theory for the distribution of suspended sediment concentration due to standing waves was obtained on the basis of the concept of "delay distance" which accounted for the fluid-particle interaction and the inertia effect of sediment particles. The purpose of this paper is to make clear the physical dependence of delay distance to wave and sediment characteristics. The evaluation of delay distance from experimental results of distribution profiles of suspended sediment concentration is made by the assumption that the horizontal diffusion coefficient of suspended sediment is nearly equal to the vertical one.
