Descriptions of the data in each subdirectory are given to facilitate understanding of this model archive. Files descriptions are provided for select files to provide additional information that may be of use for understanding this model archive. The models in this archive are all hypothetical models that do not relate to any specific geographic location. Source code for MODFLOW-2005 and MODPATH can be downloaded from the following U.S. Geological Survey-Office of Groundwater website: http://water.usgs.gov/software/ground_water.html or found in the ‘Source’ directory. MODFLOW 2005 and MODPATH were compiled using the Intel Fortran Compiler for 64-bit operating systems. Source code for MT3DMS can be obtained from http://hydro.geo.ua.edu/mt3d/ or found in the ‘Source’ directory. Source code for EndPointAnaylzer can be found in the ‘Source’ directory. EndPointAnaylzer was written specifically for this project. It is not expected to be useful for other projects. The model was run on the Windows 10 Home 64-bit operating system. Support is provided for correcting errors in the data release and clarification of the modeling conducted by the U.S. Geological Survey. Users are encouraged to review the complete model documentation report DOI:10.1111/gwat.12603) to understand the purpose, construction, and limitations of this model. Reconstructing the model archive from the online data release: ------------------------------------------------------------- The model archive is available as a data release from: doi:10.5066/F7Z0369Z (model DOI) The models will run successfully only if the correct directory structure is correctly restored. The model archive is broken into several pieces to reduce the likelihood of download timeouts. Small files (readme.txt and modelgeoref.txt) are available as uncompressed files. All other files are zipped at the subdirectory level. For example, the files in the "georef" subdirectory are zipped into a zip file named "georef.zip". All zip files should be unzipped into a directory with the same name as the zip file name without the .zip extension. The highest-level directory structure of the model archive is: doi:10.5066/F7Z0369Z/ ancillary/ bin/ georef/ model/ output/ source/ webrelease/ The full directory structure of the model archive and the files within each subdirectory are listed below. Running the model(s): -------------------- Sixty different simulations are included in this archive. Each simulation has a name, listed below, which has an associated batch file used to run the corresponding simulation. To run the models, first extract the programs in bin.zip to the bin subdirectory and create the output subdirectories for the models. Each model can be run by double-clicking the associated batch file. The MODPATH and MT3DMS models rely on output from the corresponding MODFLOW model as part of their input so to run them, either the corresponding MODFLOW model must be run first or the previously generated output must already be present in the appropriate output directories. The EndpointAnalyzer models rely on output from both MODFLOW and MODPATH as part of their input so to run them, either the corresponding MODFLOW and MODPATH models must be run first or the previously generated output must already be present in the appropriate output directories.

Usage: EndPointAnalyzer can be run either interactively or from the command line. To run EndPointAnalyzer interactively, the user double-clicks on its icon in Windows Explorer. The user must specify the locations of the endpoint, pathline and budget (cell-by-cell) flow files on the "Files" tab and also the uppermost layer of the model that contains arsenic. On the Flows tab, the user must specify the column, row, and layers of the cells containing the well. To perform the analysis, the user selects "File|Analyze." EndPointAnalyzer will read the flows from the Budget file and use them to fill in the remainder of the table on the "Flows" tab. On the Files, tab, it will display the amount of flow that passed through layers containing arsenic and the amount of flow that did not pass through layers containing arsenic. The Chart tab will display a plot of cumulative flow vs. travel time for the flow through till and bedrock where the till is the layers that do not have arsenic and the bedrock is the layers that do contain arsenic. Individual series on the plot can be turned on or off by clicking on checkboxes next to the legend for each series. The check boxes can be hidden or displayed again by selecting "Toggle Checkbox Visibility" in the main menu. The input for the analysis can be saved by selecting "File|Save." The file input can be opened again by selecting "File|Open" and selecting a file that was previously saved. The results of the analysis can be saved by selecting "File|Save Analysis". The plot on the "Chart" tab can be saved as an image by selecting "File|Save Plot." When running EndPointAnalyzer from the command line, two command line parameters can follow "EndPointAnalyzer.exe". Both represent the names of files. The first file will be the input for EndPointAnalyzer as saved previously in an interactive session. The second file will be the analysis output file generated by EndPointAnalyzer. \georef\ Description: ----------- This directory contains a shape file defining the active and inactive areas of the model.
