Using Rasters with Map to MODFLOW

For some time GMS has included the capability to use TINs with the Map->MODFLOW command. The next version of GMS will also include the capability to use Rasters with the Map->MODFLOW command similar to how TINs can be used now. In the conceptual model, the user will associate the desired Raster with the Head/Elevation assigned to a point, node, arc, or polygon. When the Map->MODFLOW command is executed the Head/Elevation for the boundary condition is extracted from the Raster using the cell center where the boundary condition is applied. The figure below shows how/where the Raster can be assigned to a point/node/arc/polygon.

PEMEX Conference

From Aug 26 to 30, PEMEX hosted the "Septimo Seminario International de Respuesta a Emergencias, Caracterizacion y Remediacion de Sitios Impactados por Hidrocarburos" in Mexico City, Mexico. The keynote speaker at the conference was Nobel laureate, Dr Mario Molina. He gave a presentation on global warming.

Alan Lemon from Aquaveo was invited to attend and give a presentation on using GMS for site characterization and flow and transport modeling of impacted sites. The presentation gave some background on the modeling process and how GMS can be used to characterize and model impacted sites. Another lecturer, Dr. Willis Weight, also shared many case studies of applied modeling using GMS. The attendees were particularly impressed with the visualizations demonstrated by Dr. Weight. Many thanks to the conference organizers for the invitation to present. Special thanks to Jorge Chirpas, Paula Andrea Martinez, and Cuauhtemoc Luna for their many efforts before, during, and after the conference.

GMS Training at Los Angeles Department of Water and Power

From August 12 to 15, members of the GMS team at Aquaveo conducted training for the Los Angeles Department of Water and Power (LADWP). The introductory Groundwater Flow and Transport Modeling class was presented to LADWP employees. The class included lectures, demos, hands on exercises, and daily tests to verify that the students could complete modeling problems. We covered MODFLOW, PEST, MODPATH,  and MT3DMS. Additionally we talked about borehole data, subsurface characterization, GIS data, and how to integrate this data into groundwater models. The class was a great success. The attendees really appreciated the power and simplicity of GMS and the conceptual modeling approach. Many thanks to the attendees.

ESRI International User Conference 2013

Join us at the 2013 ESRI International User Conference July 8-12, 2013 in San Diego, California. This year marks the 32nd convening on the International Conference on GIS technology. If you will be attending this conference, please stop by the Aquaveo booth to say hello. This conference typically enjoys a lot of support from the engineering community engaged in geographical information systems. It will be a great opportunity to connect with and learn from experts in the field.

We enjoyed seeing many of you at this year's MODFLOW and MORE 2013: TRANSLATING SCIENCE INTO PRACTICE conference. We had a booth, a couple of posters, and a couple of presentations this year. One poster showed MODFLOW-USG refined grids of different types. The other poster was on MODFLOW Server (images below). Dr. Norm Jones gave a very interesting presentation on Monday on his paper entitled Debating the Long-Term Impact of the Southern Nevada Pumping Project based on consulting work done at Aquaveo. One of Norm's graduate students, Scott Christensen presented on Wednesday on his paper entitled A web-based groundwater mapping and visualization tool using Google Earth which is based on work done partly at Aquaveo and partly at BYU.
