The dramatic advances in the efficiency of digital computers during the past decade have provided hydrologists with a powerful tool for numerical modeling of groundwater systems. Introduction to Groundwater Modeling presents a broad, comprehensive overview of the fundamental concepts and applications of computerized groundwater modeling.
The book covers both finite difference and finite element methods and includes practical sample programs that demonstrate theoretical points described in the text. Each chapter is followed by problems, notes, and references to additional information. This volume will be indispensable to students in introductory groundwater modeling courses as well as to groundwater professionals wishing to gain a complete introduction to this vital subject.
- Systematic exposition of the basic ideas and results of Hilbert space theory and functional analysis
- Great variety of applications that are not available in comparable books
- Different approach to the Lebesgue integral, which makes the theory easier, more intuitive, and more accessible to undergraduate students
Graduate students in groundwater hydrology courses

"It can be readily understood by all newcomers to numerical methods requiring only basic mathematical techniques....Short FORTRAN-computer programs for almost every problem...is a great advantage of the book....This book is as good as a complete and very detailed university course." --JOURNAL OF GEOPHYSICS
"Very timely....The authors have succeeded in avoiding complex formulated expressions without losing mathematical consistency....This introductory textbook...will be very useful in the development of college hydrogeology courses." --GROUNDWATER MODELING NEWSLETTER
"A clear, concise little volume on a subject that has needed such a treatment. It provides the best introduction to date on the most important tool of groundwater hydrology, the computer model...." --CHOICE
"This well-written, soft-bound book is a very good treatment of numerical methods applied to modeling ground water flow....The book will also be valuable as a reference for practitioners working in the area of ground water flow. I personally would buy the book for my own library." --WATER RESOURCES BULLETIN
