Nofziger, D. L. AND J. Wu. CHEMFLO-2000: INTERACTIVE SOFTWARE FOR SIMULATING WATER AND CHEMICAL MOVEMENT IN UNSATURATED SOILS. U.S. Environmental Protection Agency, Washington, DC, 2003.
Impact/Purpose:
To provide software which enables users to define water and chemical movement systems.
Description:
The movement of water and chemicals into and through soils has a large impact upon our environment and the entire ecosystem. Understanding these processes is of great importance in managing, utilizing, and protecting our natural resources. This software was written to enhance our understanding of the flow and transport processes. It was written primarily as an educational tool. As a result it is highly interactive and graphics oriented. This version of the software expands on that of a 1989 version by providing a graphical user interface and other enhancements. The software enables users to define water and chemical movement systems. The software then solves mathematical models of these systems and displays the results graphically.
The manual presents features of the software, explanations and examples of its use, its limitations, the mathematical equations used to describe the flow and transport systems, and the numerical methods used to solve these equations. The manual also includes a set of numerical experiments that illustrate flow and transport principles and enable users to understand the importance of different soil properties and other physical and chemical factors on water and chemical movement.
