NEW TO THIS EDITION
Chapter 1: Extensive updates and changes have been made to Chapters 1 for the 5th edition. Chapter 1 has been completely rewritten with a more introductory coverage of topics including simple rainfall runoff and hydrograph analysis with new examples and completely revised homework problems.
Chapter 2: This chapter now begins with the concept of the unit hydrograph and includes hydrologic losses such as evaporation and infiltration. New examples have been added on Green and Ampt infiltration, as well as many additional homework problems.
Chapter 4: There is expanded coverage and new examples on flood routing in Chapter 4. Many of the older numerical schemes have been simplified or removed and new homework problems have been added to streamline the chapter.
Chapter 5: Hydrologic Simulation Models, written by Zheng Fang and George Doubleday, presents updated methods for simulating rainfall and runoff, flood hydrograph prediction, and flood control options in a watershed. The HEC-HMS (2010) model is highlighted with completely new examples and a new detailed case study, including consideration of flood control alternatives. All new homework problems have been written as well.
Chapter 12: This chapter is written by Jude Benavides with major updates from Heather Winter, and reviews some of the emerging trends in flood control methods and floodplain management, a vital topic given recent storm events in the U.S. such as Hurricane Irene in the northeast. A detailed discussion of massive hurricane impacts along the Gulf Coast, including Hurricane Katrina and Ike, two of the most damaging hurricanes in history, has been added to the 5th edition. Also, the newly released 2010 radar-based flood alert system in Houston is described in detail. (See fas3.flood-alert.org).
Chapter 13: This is brand new and includes emphasis on the San Antonio River and Edwards Aquifer System in Central Texas, the Colorado River Basin, including Hoover and Glen Canyon Dams, and the Thames River in England. The chapter also briefly highlights international water issues in China and Southeast Asia. This chapter was designed to introduce engineering students to real-world case studies of large projects that have been implemented. In some cases, engineers are being forced to development better management practices to combat overuse and changing conditions; in others projects are being completely re-evaluated. The book ends with a discussion of the changing global condition and the need for sustainable interaction between human and natural systems.
