 Describes over 50 computer models developed with 8 different software packages
 Enables nonprogrammers to develop customized models for a wide range of environmental systems
 Presents models for processes, spills, groundwater cleanup, and more
 Reviews fundamental concepts of modeling, mathematics, and natural and engineered systems
Modeling Tools for Environmental Engineers and Scientists enables environmental
professionals, faculty, and students with minimal computer programming skills to develop
computerbased mathematical models for natural and engineered environmental systems.
The author illustrates how commercially available syntaxfree authoring software can be
adapted to create customized, highlevel models of environmental phenomena in
groundwater, soil, aquatic, and atmospheric systems, and in engineered reactors.
This book includes a review of mathematical modeling and fundamental concepts such
as material balance, reactor configurations, and fate and transport of environmental
contaminants. It illustrates, using numerous examples, how mathematical and dynamic
modeling software can be applied in analyzing and simulating natural and engineered
environmental systems. The tools and examples included are applicable to a wide range
of problems, both in the classroom and in the field.
