Diffusion Models of Environmental Transport provides more than 40 analytical models of diffusion and advective-diffusion in one, two, and three layer systems, subject to a wide range of boundary and initial conditions. Reible and Choy use their 20-plus years of combined experience to create a thorough exploration of fate and transport models. The authors supply complete details of the solutions to the models, with Mathcad spreadsheets to aid in their use, for those who wish for a deeper understanding. For others, who do not have the time or the need, the solutions themselves are ready to be picked up and used.

Summary
Fate and transport models are critical components in the determination of the exposure to and risk from hazardous contaminants. This text provides more than 40 analytical models of diffusion and advective-diffusion in one, two, and three layer systems, subject to a wide range of boundary and initial conditions.
