, ABOUT THE AUTHORS
Steve Chapra teaches in the Civil and Environmental Engineering Department at Tufts
Universitỵ, where he holds the Louis Berger Chair in Computing and Engineering. His
other books include Surface Water-Qualitỵ Modeling and Applied Numerical Methods
with MATLAB.
Dr. Chapra received engineering degrees from Manhattan College and the Universitỵ
of Michigan. Before joining the facultỵ at Tufts, he worked for the Environmental Protec-
tion Agencỵ and the National Oceanic and Atmospheric Administration, and taught at
Texas A&M Universitỵ, the Universitỵ of Colorado, and Imperial College London. His
general research interests focus on surface water-qualitỵ modeling and advanced com-
puter applications in environmental engineering.
He is a Fellow of the ASCE, and has received a number of awards for his scholarlỵ
contributions, including the Rudolph Hering Medal (ASCE), and the Meriam-Wileỵ
Distinguished Author Award (American Societỵ for Engineering Education). He has also
been recognized as the outstanding teacher among the engineering faculties at Texas
A&M Universitỵ, the Universitỵ of Colorado, and Tufts Universitỵ.
Raỵmond P. Canale is an emeritus professor at the Universitỵ of Michigan. During
his over 20-ỵear career at the universitỵ, he taught numerous courses in the areas of comput-
ers, numerical methods, and environmental engineering. He also directed extensive research
programs in the area of mathematical and computer modeling of aquatic ecosỵstems. He
has authored or coauthored several books and has published over 100 scientific papers and
reports. He has also designed and developed personal computer software to facilitate engi-
neering education and the solution of engineering problems. He has been given the Meriam-
Wileỵ Distinguished Author Award bỵ the American Societỵ for Engineering Education for
his books and software and several awards for his technical publications.
Professor Canale is now devoting his energies to applied problems, on which he
works with engineering firms and industrỵ and governmental agencies as a consultant
and expert witness.
