This course will provide an overview of the basic foundations of pollutant transport and dispersion phenomena in the environment including surface water, atmosphere, and groundwater media. The emphasis of the course will be on mathematical formulation of transport equations, analytical solutions, physical insights, methods of analysis of tracer breakthrough curves, spatial and temporal moments analysis. Although numerical modeling is not the primary objective of the course, the students will be provided with the knowledge to build a modest computational toolbox using random-walk particle tracking to visualize and quantify transport processes. Computation of analytical solutions presented in the course will require some knowledge of scientific programming. However, the students will gain such competency during the course.Prerequisites: Undergraduate fluid mechanics (570.351 or equivalent) and differential equations.
