New Guide for D5718-95 (2013) Standard Guide for Documenting a Ground-Water Flow Model Application
1. Scope
1.1 This guide covers suggested components to be included in documenting and archival of numerical ground-water flow
model applications. Model documentation includes a written and graphical presentation of model assumptions and objectives, the conceptual model, code description, model construction, model calibration, predictive simulations, and conclusions. Model archival refers to a file or set of files (in both written and digital format) that contains logs of significant
model simulations (that is, calibration, sensitivity and prediction simulations), supplemental calculations, model documentation, a copy of the model source code(s) or executable file(s) used, or both, and input and output data sets for significant model simulations.
1.2 This guide presents the major steps in preparing the documentation and archival for a ground-water flow model
application. Additional information on ground-water model documentation can be found in EPA-500-B-92-006.2
1.3 This guide is specifically written for saturated, isothermal, ground-water flow model applications. The elements
presented for documentation and archival are relevant and applicable to a wide range of modeled processes (in and out of
the realm of ground-water flow) and can be tailored for those applications.
