Models of pollutant transport have become increasingly important tools for the engineer and the policy maker. In the realm of water-quality modeling, three different classes of models have evolved to solve the governing advection-diffusion transport equations. These include grid-based models, random-walk models and hybrid models. In this paper, the authors compare the three approaches through a series of modeling experiments. Simulations for several hypothetical scenarios were conducted in zero, moderate, and heavy shear flow fields. These comparisons serve as a case study investigating primary differences and similarities among these models, and the relative merits and problems with both.
