Global climate change is expected to have major impacts on water resources and aquatic ecosystems. This prospect presents planners, who are already struggling to meet the demands of growing populations and economies, with new challenges. This volume examines these challenges and the resulting conceptual issues for water planning and project evaluation practices. The book is the first attempt to consider whether and how water resources, planning principles and evaluation criteria should be altered in view of the potential impacts of anthropogenically induced climate change. The principles and procedures that are in use today along with new approaches to nonstructural flood plain management, watershed management, water markets, and wetland banking will serve as the basis for the policies and strategies that deal with climate variability and anticipated change. This collection of papers reviews what water management ideas work, which ones need to be changed, and how planners and managers should begin incorporating aspects of risk and uncertainty into management decisions to deal expertly with climate change.

While creativity plays an important role in the advancement of computer science, great ideas are built on a foundation of practical experience and knowledge. This book presents programming techniques which will be useful in both AI projects and more conventional software engineering endeavors. My primary goal is to enter tain, to introduce new technologies and to provide reusable software modules for the computer programmer who enjoys using programs as models for solutions to hard and interesting problems. If this book succeeds in entertaining, then it will certainly also educate. I selected the example application areas covered here for their difficulty and have provided both program examples for specific applications and (I hope) the method ology and spirit required to master problems for which there is no obvious solution. I developed the example programs on a Macintosh (TM) using the Macintosh Common LISP (TM) development system capturing screen images while the example programs were executing. To ensure portability to all Common LISP environments, I have provided a portable graphics library in Chapter 2. All programs in this book are copyrighted by Mark Watson. They can be freely used in any free or commercial software systems if the following notice appears in the fine print of the program's documentation: "This program contains software written by Mark Watson." No royalties are required. The program miniatures contained in this book may not be distributed by posting in source code form on public information networks, or in printed form without my written permission.
