Water Management Models: A Guide to Software is designed to make the inventory of modeling tools more accessible to water management professionals. The purpose of the book is to assist water managers, planners, engineers, and scientists in sorting through the maze of models to understand which ones might be most useful for their particular modeling needs. Information is provided to facilitate identification, selection, and acquisition of software packages for a broad spectrum of water resources planning and management applications.

An extremely large number of water management models that provide a broad range of analysis capabilities have been reported in the published literature. Many other computer programs have been developed and applied successfully by water agencies and firms without being published. Commercial software products, which are used extensively in business, education, science, engineering, and other professional fields, also play important roles in environmental and water resources planning and management. The number and complexity of software packages can be overwhelming for anyone attempting to sort through the maze of models and understand which ones might be most useful for a particular application. The purpose of this book is to assist water managers, planners, engineers, scientists, and educators in locating the optimal computer programs for their particular needs.
This book deals with generalized operational water management models, as defined in Chapter 1. The majority of the models cited are public domain. Federal agencies and other entities that develop and distribute water management computer programs are discussed in Chapter 2. Chapter 3 covers general-purpose software packages that are applicable to several or all of the water management model categories of Chapters 4 through 10, either as complete models or as pre- and postprocessor programs. The software cited in Chapter 3 includes popular commercial programs marketed by the software industry as well as models developed within the water management community.
The several hundred models noted in this book are a relatively small subset of all the water management models reported in the literature. Citing of particular computer programs does not imply that other excellent generalized operational water management models are not available.
Chapters 4 through 10, respectively, are devoted to each of the following categories of water management models:
Chapter 4models for demand forecasting and balancing supply with demand
Chapter 5water distribution system models
Chapter 6ground-water models
Chapter 7watershed runoff models
Chapter 8stream hydraulics models
Chapter 9river and reservoir water quality models
Chapter 10--reservoir/river system operation models. Of course, computer models are used in many other areas of water management as well. However, the selected categories account for a major portion of the more common frequent applications. Computer programs in each of these major categories are applied widely by water resources and environmental professionals.
Each of the seven chapters include (1) an introductory overview of modeling applications, processes being modeled, pertinent literature, and model categorization; (2) a review of available models; and (3) a comparison of programs selected for inclusion in the Model Inventory presented as an appendix.
The Model Inventory Appendix includes a collection of 38 generalized water management models representing the seven categories of Chapters 4 through 10. Thus, a general overview of many models is combined with a focus on a selected few. An attempt was made to select several models covering a broad range of capabilities in each category. Preference was given to models with a proven record of successful application. A few of the models are more or less accepted standards in the water management community for certain types of computations; however, several of the selected models are relatively new and have not yet been applied widely. Inclusion of only selected models in the Inventory Appendix does not mean other excellent models are not also available. Practitioners should consider the entire spectrum of modeling methodologies in formulating a modeling and analysis approach for their specific applications.
However, the models included in the Appendix provide an excellent starting point for investigating available capabilities. These highlighted models are readily available generalized software packages that provide a broad range of analysis capabilities and are designed for practical application.
