Hughes Dorothy F. Sifuentes Jeremy T. White 2016 Publication Scientific Investigations Report 2016-5022 Reston, VA, USA U.S. Geological Survey https://doi.org/10.3133/sir20165022 A three-dimensional, variable-density solute-transport model (SEAWAT) was developed to examine causes of saltwater intrusion and predict the effects of future alterations to the hydrologic system on salinity distribution in eastern Broward County, Florida. The model was calibrated to conditions from 1970 to 2012, the period for which data are most complete and reliable, and was used to simulate historical conditions from 1950 to 2012. The model was used to (1) evaluate the sensitivity of the salinity distribution in groundwater to sea-level rise and groundwater pumping , and (2) simulate the potential effects of increases in pumping, variable rates of sea-level rise, movement of a salinity control structure, and use of drainage recharge wells on the future distribution of salinity in the aquifer. This USGS data release contains all of the input and output files for the simulations described in the associated model documentation report (https://doi.org/10.3133/sir20165022). This data release also includes (1) preprocessing python scripts and associated input data files for creating the sensitivity and scenarios runs, (2) flopy source code, and (3) SEAWAT (v4) source code. This groundwater model was created to examine causes of saltwater intrusion and predict the effects of future alterations to the hydrologic system on salinity distribution in eastern Broward County, Florida. The development of the model input and output files included in this data release are documented in U.S. Geological Survey Scientific Investigations Report 2016-5022 (https://doi.org/10.3133/sir20165022). 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 (https://doi.org/10.3133/sir20165022) to understand the purpose, construction, and limitations of this model. The models, along with pre- and post-processing tools, will run successfully only if the original directory structure is correctly restored. The model archive is broken into several pieces to reduce the likelihood of download timeouts. Instructions for reconstructing the original directory structure and running the models included in this data release and described in the model documentation report can be found in the readme.txt ASCII file which can be downloaded as part of this data release. The structure of the archive and associated download files were modified on 3/21/2016 to exactly match the proposed U.S. Geological Survey Office of Groundwater groundwater model archive structure. Model results in the revised structure are identical to the previous version (version 1.0) of this data series. 19500101 20110531 publication date Complete Not planned -80.78 -80.018 26.487 25.919 USGS Thesaurus usgsgroundwatermodel SEAWAT Groundwater InlandWaters Groundwater Model Transport Model Saltwater Intrusion ISO 19115 Topic Category geoscientificInformation inlandWaters environment USGS Metadata Identifier USGS:41273e3a-f3e3-416b-acb9-fe65fe86bdb4 Geographic Names Information System Florida Biscayne aquifer Fort Lauderdale Broward County None.

SEAWAT version 4 source code for MT3DMS was modified to create observation output that is easier to post-process with python. The standard version of SEAWAT version 4 can also be used but observation output would have a different format that would not be able to be post processed with the python scripts included in this data release. The flopy python package (version 3.0.3) has also been included. flopy post-processing methods are used in the python post-processing scripts to read binary MODFLOW and MT3DMS output files. This version of flopy was developed for python 2.7 and may not run in more recent versions of python. flopy version 3.0.3 requires NumPy 1.9 (or higher) and matplotlib 1.4 (or higher). The mapping and cross-section capabilities in the flopy version 3.0.3 require Pyshp 1.2 (or higher). The cluster_repo python package has also been included because several of the python pre- and post-processing scripts use the functionality in classes and methods. In particular, the classes and methods in shapefile.py and pestUtil.py are used. cluster_repo requires NumPy 1.9 or higher and pandas 0.15.2 or higher. The post-processing scripts also require the basemap 1.0.7 or higher. 1.1 https://water.usgs.gov/GIS/dsdl/gwmodels/SIR2016-5022/source.zip None 20201117 U.S. Geological Survey Ask USGS -- Water Webserver Team mailing
