Application of Visual C++ and MFC to a Finite Difference
Vadoze Zone Mass Transport Model
Abstract
VLEACH, a finite difference vadose zone contaminant
transport model, is a computer program for estimating the impact on the
groundwater resource due to the transport of an organic contaminant located in
the unsaturated zone above the groundwater table. This model was initially
developed by CH2M Hill Inc. for the U.S. Environmental Protection Agency,
Region IX in 1990. Since then, it has been widely used to assess the potential
groundwater impacts from existing soil contaminants. This program was written
in Fortran 77 with a text-based user interface. The major objective of this
thesis project is to develop a Windows-based version of VLEACH to facilitate
the increasing use of the program. The new program was designed using
object-oriented concepts and was implemented in C++ within the Visual C++
environment. The new product, WINVLEACH, is very user friendly with added
error-checking functionality. Future modification can be done easily by adding
more classes or by inheriting some of the existing classes. A case study has
shown that WINVLEACH is able to produce the same result as the original code,
indicating the conversion has been successful.
