Abstract

A diffusion model of clay-water flow is formulated to determine the time dependent concentration distribution of suspended clay in a two dimensional periodic flow. Taking into account the entrainment rate of the clay particle from the bed, the integrated diffusion equation to yield a solution of the time-variation of the clay concentration in the vicinity of the channel bed is derived. In addition the original diffusion equation is solved by means of the finite element method. An experiment was conducted in a recirculating two dimensional channel where sinusoidal current variation was generated upon the clay-water mixture. Results obtained from the experiment are compared with those derived from the model.
