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. Four model data sets are archived for this groundwater study. Simulations for this model were run with MODFLOW-2005 version 1.11.00 (Harbaugh, 2005). MODFLOW-2005 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. The model was run on the Windows Server 2009 Edition (64-bit) operating system (Service Pack 1). 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 (http://dx.doi.org/10.3133/SIR20165138) 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: http://dx.doi.org/10.5066/F7TB151D The models will run successfully only if the correct directory structure is 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 original model archive is: SIR2016-5138/ ancillary/ bin/ georef/ model/ output/ source/ The full directory structure of the model archive and the files within each subdirectory are listed below. Running the model(s): -------------------- Four different simulations are included in this archive. Two simulations are groundwater-flow simulations that used a previously calibrated regional groundwater-flow model (Buxton and Smolensky, 1999). Two simulations are particle-tracking simulations. Each simulation has a name, listed below, which has an associated name file used to run the corresponding simulation. When MODFLOW-2005 is executed, a single prompt is issued for the name file that specifies the input files to be used in the simulation, as well as, the output files that are created. Responding to this prompt with the name file listed below will initiate the corresponding simulation. The simulations that are documented can be run by opening a command line/terminal in the model subdirectory and typing: ../bin/mf2005.exe .nam the steady-state simulations ../bin/mp6.exe .mpsim the steady-state particle tracking simulations Summary of the simulations --------------------------- SIMULATIONS DESCRIPTION OF SIMULATION TIME PERIOD SIMULATED stop MODFLOW-2005 Steady-state simulation Average 1968-1983 withdrawals ptstop Particle tracking with particles stopping at Average 1968-1983 withdrawals weak sinks ptpassthru Particle tracking with particles passing thru Average 1968-1983 withdrawals weak sinks Files: ----- readme.txt : ASCII file which documents the model archive data release.
