F., Clark, Brian R., and Feinstein, Daniel T., 2017, MODFLOW-NWT model used to evaluate effects of complexity on head and flow calibration in the Fox-Wolf-Peshtigo watersheds, Wisconsin: U.S. Geological Survey data release. http://dx.doi.org/10.5066/F73J3B3P The underlying directories contain all of the input and output files for the simulations described in the model documentation report and an ipython notebook used to generate shapefiles that were used as input for developing figures 12, 13, and 19 of the report. The model simulations were run with version 1.0.9 (7-1-2014) of MODFLOW-NWT. The official 64-bit source code has been included in the model archive. The MODFLOW-NWT code was compiled on a personal computer with the Intel(R) Core(TM)2Duo CPU T9500 chipset, running the Microsoft Windows XP Professional operating system, using the Microsoft Visual Studio 2012 Version 11.0.50727.1 development environment and the Intel(R) Visual Fortran Version 13.0.3636.11 compiler. The model was run on a 64-bit computer running the Windows 7 Enterprise 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 model documentation report (http://dx.doi.org/10.3133/sir20175010) to understand the purpose, construction, and limitations of this model. Reconstructing the data release from the online data release: This data release is available from: http://dx.doi.org/10.5066/F73J3B3P The models will run successfully only if the original directory structure is correctly restored. The data release 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 data release is: SIR2017-5010/ ancillary/ bin/ georef/ model/ output/ source/ Running the model(s): The model files are designed to be run from the Windows command line/terminal (type cmd into the "Search programs and files" dialog after selecting the "Start" menu). Each model is designed to run from within its own subdirectory. For example, to run the 1-layer zoned model, open the command line/terminal within the 1-layer-zoned subdirectory (or change to that directory). From the command line/terminal, type "1-layer.bat" (no quotes) to launch the batch file that calls the appropriate executable and input files. The other simulations can be run in a similar fashion by changing to the appropriate model subdirectory and substitute "1-layer-zoned.bat" with the name of the appropriate batch file. Possible batch files are: 1. 1-layer-zoned.bat 2. 5-layer-zoned.bat 3. 5-layer-hetero.bat readme.txt : This file documents the structure, directories, input/output files, and instructions on how to run the model in this data release. modelgeoref.txt : ASCII file with the four corners of the model domain in decimal degrees. ancillary directory: This directory contains reference shapefiles, raster output representing the coarse fraction of glacial deposits as illustrated in figure 9 of the report, and also PEST files that were used to make comparisons among the models. The PEST files are provided here as input into an ipython notebook (Source directory) that was used to generate figures 12, 13, and 19 of the report. bin directory: This directory contains the compiled code "MODFLOW-NWT_64.exe" that was used to run the modflow models. georef directory: This directory contains a shapefile called "SIR2017_5010.shp", which defines the extent of model domain and active portions of the model. model directory: This directory contains model input files. The directory contains the following subdirectories: FWP1L_zK subdirectory: This subdirectory contains model input files specific to the 1-layer, zoned hydraulic conductivity model. FWP5L_zK subdirectory: This subdirectory contains model input files specific to the 5-layer, zoned hydraulic conductivity model. FWP5L_hK subdirectory: This subdirectory contains model input files specific to the 5-layer, heterogeneous hydraulic conductivity model. externalfiles subdirectory: This subdirectory contains model input files used by more than one model. output directory: This directory contains model output files for the model input files included in the model directory. The output directory contains the following subdirectories: Output.FWP1L_zK subdirectory: This subdirectory contains model output files specific to the 1-layer, zoned hydraulic conductivity model. Output.FWP5L_zK subdirectory: This subdirectory contains model output files specific to the 5-layer, zoned hydraulic conductivity model. Output.FWP5L_hK subdirectory: This subdirectory contains model output files specific to the 5-layer, heterogeneous hydraulic conductivity model. Output from the models included in the "model" directory will be written to the associated 'model' directory. That is, output files will be written to the directory that contains the NAM file for the model that is being run. This prevents archived model output in the "output" subdirectories from being over-written and thus facilitates comparisons. source directory: This directory contains source files to compile MODFLOW-NWT, version 1.0.9 and original documentation package for the MODFLOW-NWT version 1.0.9 release, in addition to a python notebook representing the executable source code for processing simulated results to generate shapefiles that were used to generate figures 12, 13, and 19. The python notebook is started by opening a command prompt, changing to this directory, and typing "ipython notebook" (no quotes) at the prompt. A webpage will open; click on "Calib_comparisons.ipynb" to open the notebook. To run the notebook, select "Cell", then "Run All". Note that an installation of python version 2.7 must be present on the computer, and compatable versions of the following python libraries (and their dependancies) must be installed in that installation: geopandas, matplotlib, numpy, os, pestools, shapely source.zip : The zipped souce code for MODFLOW-NWT version 1.0.9
