Environmental Modeling, Second Edition combines engineering transport fundamentals and equilibrium aquatic chemistry. It brings a uniquely contemporary perspective to the assessment of environmental quality. In addressing key questions about fate, transport, and long-term effects of chemical pollutants in the environment, this inherently practical book gives readers the important tools they need to develop and solve their own mathematical models. The book contains detailed examples from a wide range of crucial water quality areas: conventional pollutants in rivers, eutrophication of lakes, and toxic organic chemicals and heavy metals in both surface and groundwaters.
