Training Mexico City, Mexico

A GMS training course was held from March 5-8 in Mexico City, Mexico. Alan Lemon of the GMS development team and Dr. Willis Weight of Carroll College, Montana taught the course.

The course was well attended. More than 20 people attended the course. There was a wide variety in the amount of experience with groundwater modeling. Some attendees had been building models for years, while others were relatively new to groundwater modeling. Also, the attendees came from many different backgrounds including: professors at universities, consultants, and students. Based on the comments submitted after the course, the attendees felt like they all learned something valuable that they could use in their work. Many attendees commented on how much easier it was to build models using GMS than other MODFLOW preprocessors. They appreciated using the conceptual model approach and having their data independent of a MODFLOW grid.

Thanks to Jorge Chipres and Catalina Morato for their efforts in organizing the course.

Exporting 3D Grids to Shapefiles

In GMS 8.2 we added the ability to export a 3D grid to a shapefile. All layers of the grid are exported, along with the active data set and the grid cell activity (IBOUND) and data set activity (dry cells) if they exist. Here is the list of the attributes that get exported:
  • cell ID
  • cell I
  • cell J
  • cell K
  • grid cell activity
  • active scalar data set values
  • active data set activity (if it exists)
A simple definition query using the grid cell activity and K fields can be created in ArcMap to see one layer of the grid at a time. For example, the following figure shows the head solution on the third layer of the grid from the lake package tutorial as a shapefile in ArcMap.


MODFLOW-NWT Interface

With the release this week of GMS 8.2, GMS includes support for MODFLOW-NWT including the UPW package and NWT solver. Compiled versions of the MODFLOW-NWT executable are included with the GMS installer, including versions for 64 bit and double precision. A new tutorial covering the NWT interface has been added and is included in the tutorial installer and is also available via the learning center.

ZONEBUDGET in GMS


GMS has an extensive tool set for working with flow budget information from MODFLOW. GMS is the only package that reports flow budget information on GIS features. For example, if polylines or polygons were used to create drain boundary conditions in MODFLOW then GMS will report the flow into or out of the model from the polyline/polygon. For some time now, GMS has allowed users to view flow budgets for selected sub-areas of their models as well as the ability to assign zone budget ids to cells and extract flow budget information.

Beginning with GMS 8.2, we will now include an interface to USGS ZONEBUDGET. This tool is accessed by selecting the Flow Budget menu command in the MODFLOW menu. There is a USGS ZONEBUDGET tab available in the dialog. The user can set up their input options and then there is a button to launch ZONEBUDGET. The input and output files for ZONEBUDGET are written to the same directory where the MODFLOW Cell-to-cell flow file is located.

There is also a new tutorial available that shows the various ZONEBUDGET options. Go to the GMS Learning Center on http://www.aquaveo.com/gms-learning to download the tutorial.

A video that demos the ZONEBUDGET feature is available on the Aquaveo youtube channel.
