Title: Task 23 -- User`s guide to GRI-ShowFlow

Abstract

GRI-ShowFlow is a compilation of flow and transport groundwater models under one user-friendly, graphical interface in the Microsoft{reg_sign}Windows{trademark} 3.1 environment. The groundwater models as well as the interface were derived from existing codes. The motivation behind the development of GRI-ShowFlow was twofold: (1) there is a need to compare and assess various analytical and screening-level models that are being used by regulatory agencies and (2) there is a need for the nonexpert to be able to use these screening-level models and the resulting information without expert interpretation. GRI-ShowFlow was developed for use by gas industry environmental staff who may have little experience with hydrogeology or groundwater models but must be able to quickly determine whether there is sufficient chance of groundwater contamination and whether a site does or does not require a more extensive examination. Special attention was therefore given to the Help System in GRI-ShowFlow, which aids the development of the minimal amount of data required by the program and the interpretation of the resulting data. The objective of GRI-ShowFlow is to bring together the existing EPA models in a user-friendly environment and to compare them to each other as well as to new models that contain analytical solutionsmore » to three-dimensional source descriptions. A three-dimensional body will more closely reflect the shapes of contaminant sources than one- or two-dimensional geometries. In the real world, contamination sources such as landfills, storage pits, and lagoons will, after all, occupy a three-dimensional space.« less
