Hydrodynamics and Water Quality: Modeling Rivers, Lakes, And Estuaries Zhen–Gang Ji (2008). John Wiley & Sons Inc., 111 River St., Hoboken, N.J. 07030, 678 pp., $125, hardcover, ISBN 978-0-470-13543-3.

Hydrodynamics and Water Quality provides the principles, fundamental processes, mathematical formulations, and field applications of modeling surface waters. The book discusses hydrodynamics; sediment transport; fate and transport processes of contaminants; water quality; and eutrophication in rivers, lakes, estuaries, and coastal waters. It also focuses on the impact of external sources entering a waterbody as related to total maximum daily loads. A separate chapter is devoted to describing mathematical modeling and statistical analyses that are commonly used in the studies of surface water systems. Water quality and eutrophication, an important topic, is discussed at great length. The mathematical equations of physical, chemical, and biological parameters in relation to surface water quality modeling are described with examples and illustrations. An overview of three-dimensional Environmental Fluid Dynamics Code is included in the appendix.

The writing style is smooth and lucid. Chapters have little overlapping and redundant information. The case studies on hydrodynamics modeling and water quality are pertinent and illustrative. It is easy to follow the basic concepts described in the beginning of each chapter without getting lost in mathematical equations. The useful companion CD includes a modeling package and digital files of numerical models, case studies, and model results. Overall, this book can serve as a resource for surface water modelers, as well as graduate and undergraduate students. Environmental scientists, engineers, geologists, and environmental regulators also will find this book a good reference.
