Models and Modeling

An Introduction to Models and Modeling in the Earth and Environmental Sciences

offers students and professionals the opportunity to learn about groundwater modeling, starting

from the basics. Using clear, physically-intuitive examples, the author systematically takes

us on a tour that begins with the simplest representations of fluid flow and builds through

the most important equations of groundwater hydrology. Along the way, we learn how

to develop a conceptual understanding of a system, how to choose boundary and initial

conditions, and how to exploit model symmetry. Other important topics covered include

non-dimensionalization, sensitivity, and finite differences. Written in an eclectic and readable

style that will win over even math-phobic students, this text lays the foundation for a

successful career in modeling and is accessible to anyone that has completed two semesters

of Calculus.

Although the popular image of a geologist or environmental scientist may be the rugged

adventurer, heading off into the wilderness with a compass and a hand level, the disciplines

of geology, hydrogeology, and environmental sciences have become increasingly quantitative.

Today’s earth science professionals routinely work with mathematical and computer models,

and career success often demands a broad range of analytical and computational skills.

An Introduction to Models and Modeling in the Earth and Environmental Sciencesis written for

students and professionals who want to learn the craft of modeling, and do more than just

run “black box” computer simulations.

Dr. Jerry P. Fairley received his PhD in Earth Resources Engineering from the University

of California, Berkeley. He was the Chief Hydrologist for Site Characterization on the US-

DOE’s Yucca Mountain Project (1993–1995), and worked as a modeler for the Earth Sciences

Division of Lawrence Berkeley National Laboratory. He is currently a Professor of Geology

at the University of Idaho, Department of Geological Sciences.
