Overview

Showcases beneficial methods. Next Generation Environmental Models Computational Methods Workshop held at the U.S. Environmental Protection Agency (U.S. EPA) National Environmental Supercomputing Center in Bay City, Michigan, August 1995. Large-scale changes are taking place in the way modeling is performed within the U.S. EPA, and a new generation of environmental models is currently under construction. The U.S. EPA is engaging in several modeling efforts in response to Congressional mandates such as the Clean Air Act and the Clean Water Act. These mandates require the scientific modeling of the impact of pollutants on human health and the environment. The complexity of scale in environmental models has increased by several orders of magnitude, with a simultaneous demand for increased stability, accuracy, and efficiency in the computed model solution. This book showcases numerical algorithms appropriate to the subject areas listed below and explores how new algorithmic methods would benefit the U.S. EPA's environmental models and other environmental studies. The overriding theme is that better environmental models need to include more realistic physical processes and this in turn requires a large increase in computational complexity and computational power. Computational algorithms in scientific models are surveyed in subject areas such as global and regional circulation models, air quality modeling, aquatic systems, water quality modeling, groundwater transport of contaminants, and inverse problem methods for the environment. A background in numerical modeling with computers is required for understanding this book. It is written in survey form to allow cross-disciplinary readership. Dr. George Delic is with Lockheed Martin Technical Services, Inc. and is employed as a scientific computing consultant to environmental scientists at the U.S. EPA's National Environmental Supercomputing Center. Dr. Mary Wheeler is Head of the University of Texas' Center for Subsurface Modeling (CSM), which operates as a subsidiary of the Texas Institute for Computational and Applied Mathematics. She holds joint appointments in the Departments of Petroleum and Geosystems Engineering, Aerospace Engineering and Engineering Mechanics, and Mathematics. Dr. Wheeler is the first woman to hold the Ernest and Virginia Cockrell Chair in Engineering, an endowed chair at the University of Texas College of Engineering.
