IWFM Mesh Generator

(Released: November 8, 2021) This is a mesh generator that is integrated into ESRI's ArcMap software, version 10.8.x. It utilizes shapefiles to define model boundary, streams, enforcement lines, holes and wells to generate a triangular, quarilateral or mixed triangular-quadrilateral finite element mesh. It uses [Triangle](https://www.cs.cmu.edu/~quake/triangle.html), developed by Dr. Jonathan Richard Shewchuk, and [Gmsh](https://gmsh.info), developed by Christophe Geuzaine and Jean-François Remacle, as the mesh generator engines. The mesh can be converted to a shapefile to perform various data analysis to develop input data (e.g. soil properties, land use distribution, development of stratigraphic layers) for IWFM applications. Groundwater and stream nodes as well as finite elements can be numbered automatically and the IWFM mesh files can be exported to text files. After downloading the ESRI add-in installation file (MeshGenerator.esriAddin), double-click on it and follow the instructions. After installation, start ArcMap and click the "IWFM Mesh Generator" button.

IWFM Tools Add-in for Excel - 32 bit

(Released: November 15, 2022) This tool is tested under Windows 10 and installs as a new tab named "IWFM Tools" into MS Excel, and currently includes four utilities (Note: The Budget-To-Excel utility will no longer work for Budget binary files generated by IWFM v3.02 or v4.0): 1. data column export to a text file 2. Water Year-Month table generator 3. Budget-To-Excel data import utility 4. Z-Budget-To-Excel data import utility The first utility is useful when IWFM input data is prepared in Excel and when this data needs to be exported into a text file with right-aligned data columns. The second utility is used to convert time series data into a Water Year-Month table and optionally generate charts. The third and fourth utilities are used to quickly import data from IWFM Budget and Z-Budget HDF5 files into Excel. After downloading the setup file, double-click it and follow the instructions for installation.

Soil Data Builder

(Released: June 1, 2016) This tool processes the [SSURGO soil database](https://websoilsurvey.sc.egov.usda.gov/App/HomePage.htm) from NRCS and creates text files that store root zone data required by IWFM and IDC. These text files can then be opened in ESRI's ArcGIS along with the SSURGO shapefiles, and processed to generate soil parameters to be input to IWFM or IDC models. This tool requires MS Access 2007 or higher to be installed on the user's computer. Once installed, you can find the tool under Start -> All Programs -> IWFM.
