Abstract

A computer coded Lagrangian marker particle in Eulerian finite difference cell solution to the three-dimensional incompressible mass transport equation, Water Advective Particle in Cell Technique, WAPIC, was developed, verified against analytic solutions, and subsequently applied in the prediction of long term transport of a suspended sediment cloud resulting from an instantaneous dredge spoil release. WAPIC was utilized to simulate an anal ytic solution for non-equilibrium sediment dropout from an initially vertically uniform particle distribution in one-dimensional turbulent channel flow. Predicted sediment fallout rates and vertical concentration values, as a function of downstream distance were within an absolute accuracy of flow per cent of the analytic values.
