Model documentation report: Ellis, J.H., Ryter, D.W., Fuhrig, L.F., Spears, Kyle, Mashburn, S.L., Rogers, I, 2020, Hydrogeology, Numerical Simulation of Groundwater Flow, and Effects of Future Water Use and Drought for the Washita River Alluvial Aquifer, Roger Mills and Custer Counties, Western Oklahoma: U.S. Geological Survey Scientific Investigations Report 2020-5118, https://doi.org/10.3133/sir2020xxxx Model data release: Ellis, J.H., Ryter, D.W., Fuhrig, L.F., Spears, Kyle, Mashburn, S.L., Rogers, I, 2020, MODFLOW-NWT model used in Simulation of Groundwater Flow, and Analysis of Projected Water Use for the Washita River Alluvial Aquifer, Western Oklahoma: U.S. Geological Survey data release, https://doi.org/10.5066/P9PKMG6U ------------------------------------------------------------------------------------------------------------------ GENERAL The model directory and subdirectories contain all of the input and output files for the simulations described in the report. About 16 GB of space is required to unzip the model archive and run all of the simulations (excluding the soi-water-balance (SWB) files). The steady-state model represents the average 1980-2015 conditions, and is included as stress period 1. The transient model runs 1980-2015. PYTHON The groundwater-flow model in this archive runs Python 2 and use a number of modules; however, all required python is self-contained in this archive. Thus, there is no need to install any software to run the model. If you would like to install the required Python software and modules, Python 2 is available at this link in a single package: https://www.continuum.io; although, it is now depreciated. Once installed, python must be added to the system path variable under 'environmental variables.' To test if this is needed, open a command prompt (Winkey+R, type 'cmd') and type 'python' at the prompt. Additionally, to run the calibrated model, the PyEmu package is required, which is found at https://github.com/jtwhite79/pyemu and included in the 'source' folder of this archive. MODEL INFORMATION Length Unit: Feet Steady-State Stress Period length: 365 days Transient Stress Period length: 1 month (28 to 31 days) Transient Stress Period duration: January 1980-December 2015 Cell size: 350 feet uniform grid spacing Time steps per stress period: 1 Layers: 2 (Layer 1 is Quaternary-age alluvium and terrace deposits, Layer 2 is Permian-age bedrock) Output Control: Displays outputs for Time Step 1 in each Stress Period Solver: NWT System requirements The models contained in this data release were run using the executables in the bin.zip file in this data release. The simulations were run on a personal computer with 32GB Random Access Memory with 64-bit Windows 7 OS. The models will take approximately 0.8 GB of memory each to run. Support 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 model documentation report (https://doi.org/10.3133/sir2018XXXX) 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: https://doi.org/10.5066/P9PKMG6U 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. ------------------------------------------------------------------------------------------------------------------ In order to run the models, all zipped folders in the model archive must be unzipped in accordance with the directory structure shown below.

Below is a description of the corresponding model scenarios from the report with the named folder in the archive: Equal Proportionate Share (report page 68): may_xx_year (where 'xx' denotes either 20-, 40-, or 50-year timeperiods in the file name) Projected (50-Year) Groundwater Use (report page 71): current_use_xxx (where 'xxx' denotes either the 2015, average, growth, or no pumping scenarios). Hypothetical (10-year) Drought: drought Running batch files: Each simulation can be run by double clicking on the batch file in the model subdirectories. This will bring up a command prompt window which will record the simulation progress. Once the simulation has finished running, press any key to exit and close the command prompt window. Note that for the Equal Proportionate Share scenarios, there are two batch files in each folder. Ensure to use the Run_may_xx.bat (where 'xx' denotes either 20-, 40-, or 50-year timeperiods in the file name) to run the scenario. The batch files used to run the model are a combination of pre- and post processing steps, in addition to running the MODFLOW_NWT model, that are carried out through a series of python script. The models cannot be run with just the MODFLOW-NWT executable which would result in different output than are archived for each model. For some of the scenarios, the batch file that runs the scenario will delete some of the output files at the end of the scenario that aren't needed. To be able to view these files, simply edit the batch file and remove these lines. Projected (50-year) pumping scenario (current_use folders): Run the four scenarios with the batch files located in the folders below. When these batch files are run, storage is also automatically calculated at the end of the scenario. An explanation of the file name is below: \current_use_2015pump Wash1_current_50_2015pump.bat: Batch file using Python for running pre- and post-processing scripts and MODFLOW-NWT for the 50-year-use scenario with 2015 rates \current_use_avgpump Wash1_current_50_avgpump.bat: Batch file using Python for running pre- and post-processing scripts and MODFLOW-NWT for the 50-year-use scenario with mean rates for the study (model) period \current_use_growthpump Wash1_current_50_growthpump.bat: Batch file using Python for running pre- and post-processing scripts and MODFLOW-NWT for the 50-year-use scenario with increased demand rates \current_use_nopump Wash1_current_50_nopump.bat: Batch file using Python for running pre- and post-processing scripts and MODFLOW-NWT for the 50-year-use scenario with no pumping. Hypothetical (10-year) drought scenario (drought folder): Run the drought scenario with the 'Wash1_drought.bat' file. When the batch file is run, storage is also automatically calculated at the end of the scenario. Calibrated model (final_model folder): To run the calibrated model and calculate groundwater storage, use the 'Wash1.bat' file. Note that when the transient model finishes the 'Calc_storage' python script is automatically run to calculate groundwater storage. To note, due to the size of the cell-by-cell output file, this file is deleted by a routine at the end of the 'Wash1.bat' batch file after it is used by Zonebudget. Additionally, for the Zonebudget outputs, 'Zone 1' is the model area upstream of Foss Reservoir, while 'Zone 2' is the area downstream of Foss Reservoir. EPS scenarios (may folder): Run the EPS scenarios with the batch files located in the folders below. Note that when the 20-year EPS scenario is run, storage is also automatically calculated at the end of the scenario. The other batch files in each folder starting with 'Wash1' should not be used, as this is called by the batch files below to run the model. \may_20_year Run_may_20.bat: Runs the 20-year EPS scenario with normal recharge \may_20_year_dec Run_may_20_dec.bat: Runs the 20-year EPS scenario with recharge reduced 10 percent \may_20_year_inc Run_may_20_inc.bat: Runs the 20-year EPS scenario with recharge increased 10 percent \may_40_year Run_may_40.bat: Runs the 40-year EPS scenario with normal recharge \may_40_year_dec Run_may_40_dec.bat: Runs the 40-year EPS scenario with recharge reduced 10 percent \may_40_year_inc Run_may_40_inc.bat: Runs the 40-year EPS scenario with recharge increased 10 percent \may_50_year Run_may_50.bat: Runs the 50-year EPS scenario with normal recharge \may_50_year_dec Run_may_50_dec.bat: Runs the 50-year EPS scenario with recharge reduced 10 percent \may_50_year_inc Run_may_50_inc.bat: Runs the 50-year EPS scenario with recharge increased 10 percent ------------------------------------------------------------------------------------------------------------------ SUBDIRECTORY AND FILE DESCRIPTIONS modelgeoref.txt: ASCII file with the four corners of the model domain in decimal degrees. readme.txt: This file documents the structure of the model archive.
