"As a water quality professional, I found the book to be helpful and a very informative reference. It provides much needed information for solving practical environmental water resources problems through modeling. It would also be a great addition to any university library. (Journal of the American Water Resources Association, July 2009) On the whole, the topics are well organized, the prose is easy to read and understand, the style is lucid, and there is a wealth of information reflecting the knowledge and experience of the author. The book will also be useful to practicing water and environmental engineers. (Journal of Hydrologic Engineering, August 2009) This book illustrates principles, basic processes, mathematical descriptions, and practical applications associated with surface waters. It focuses on solving practical problems in rivers, lakes, estuaries, coastal waters, and wetlands. Most of the theories and technical approaches presented in the book have been implemented in mathematical models and applied to solve practical problems. Throughout the book, case studies are presented to demonstrate how the basic theories and technical approaches are implemented into models; and how these models are applied to solve practical environmental/water resources problems.Compared with the first edition, the second edition has contents increased by >40%, including >120 new/updated figures and ~450 new references. A new chapter focuses on shallow water processes in wetlands. A new chapter is devoted to extreme value theory and environmental risk analysis. A new website for the book provides sample applications that are discussed extensively in this book, including source codes, executable codes, input files, output files, model manuals, and technical reports.
