Title
A Comparison of Lagrangian and Eulerian Approaches to Modelling Water Quality in a Rectangular Harbour
Y . H . Kang,R . A . Falconer
Abstract
To simulate transport and mixing processes of pollutants in shallow waters, a particle tracking random walk model and the ULTIMATE QUICKEST scheme have been developed for the solution of the depth integrated advective diffusion equation. The Ito stochastic differential equation is derived to determine the particle displacements in the random walk model. These two mathematical models have been validated and compared with dye experiments in a rectangular harbour with tidal circulation. The numerical solutions obtained show good agreement with the physical model results in terms of the spatial mean concentration variation.
