Descriptions of the data in each subdirectory of this model archive are provided to facilitate understanding of this data release. 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. Users are encouraged to review the publication supplementary material (http://dx.doi.org/10.1080/10402381.2017.1412374) to understand the purpose, construction, and limitations of this groundwater flow model. A General Lake model and an Eutrophication model also were used to generate results described in the Lake and Reservoir Management paper (http://dx.doi.org/10.1080/10402381.2017.1412374), but are not included in this archive of the groundwater flow model (MODFLOW model). Reconstructing the archive from the online data release: ------------------------------------------------------------- This data release is available from: http://dx.doi.org/10.5066/F7F18WXW The models will run successfully only if the original directory structure is correctly restored. The data release is divided into several zipped folders 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 the follows the naming conventions and structure of the master directory listed below. The master directory structure of the original data release is: LRM2018-Anvil/ ancillary/ bin/ georef/ model/ output/ source/ readme.txt modelgeoref.txt A full listing of sub-directories associated with this data release can be found below. System requirements: -------------------- The models have been run successfully on computers running the following Windows operating systems (OS): o Windows XP Professional operating system Optional system requirements: ----------------------------- The steady-state and transients model results can be post-processed or viewed using standard MODFLOW or user-preferred post-processing utilities. 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 calibrated steady-state model, open the command line/terminal within the steadystate subdirectory (or change to that directory). From the command line/terminal, type "anvil2_SS.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 substituting "anvil2_SS.bat" with the name of the appropriate batch file. Possible batch files are: 1. anvil2_SS.bat 2. anvil2_1980.bat 3. anvil2_transient.bat 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. The archived output from the steady-state and transient model simulations are stored in the appropriate output directory. For example, steady-state simulation output can be found in the output/ directory, under the subdirectory, output.steadystate. Files: --------------------- 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/ Description: ----------- This directory contains associated netcdf model input and output files. ZIP File: ---------- ancillary.zip bin/ MODFLOW-NWT_64.exe Readme.txt Description: ----------- MODFLOW-NWT_64.exe executable file used to run the model simulations documented in this report. This executable is for a 64-bit Windows Operating System. See MODFLOW-NWT_64 (v. 1.0.9) documentation files in source\ directory more information. ZIP Files: ---------- bin.zip georef/ LRM2018_anvil.dbf/prj/shp/shx/sbx/xml/cpg/sbn readme.txt Description: ----------- This directory contains a shapefile defining the active and inactive areas of the model, as documented in the Lake and Reservoir Management paper (http://dx.doi.org/10.1080/10402381.2017.1412374). The entire domain is active. The readme.txt file and the .prj file provide projection information. ZIP Files: ---------- georef.zip model/ externalfiles/ SS1980/ steadystate/ transient/ readme.txt Description: ----------- This directory contains input files for the steady-state and transient model simulations documented in the Lake and Reservoir Management paper (http://dx.doi.org/10.1080/10402381.2017.1412374). The steady-state model (steadystate) is a base run calibrated to observed hydrologic targets for the period 1980 through 2014. The 1980 steady state model (SS1980) uses the calibrated hydraulic conductivity from the steady-state model and climatic data from 1980 and serves as the initial conditions for the transient model. The transient model is run from 1980 - 2014 and is calibrated to the monthly water level in Anvil Lake. externalfiles/ Description: ----------- This subdirectory contains model input files used by more than one model. SS1980/ Description: ----------- This subdirectory contains model input files specific to the steady-state model used to generate heads associated with climatic conditions during 1980. The output heads are used as starting heads for the transient simulation steadystate/ Description: ----------- This subdirectory contains model input files specific to the steady-state model. transient/ Description: ----------- This subdirectory contains model input files specific to the transient model.

Note, the *.cbb, *streamflow.dat, and the *hds files for the transient run are empty because these data were not needed for the Anvil Lake model and, therefore, were specified in the name file to not have any data saved to them.
