New Visual MODFLOW Premium 4.3
The industry standard is now stronger and more versatile
Obtain in-depth information by investigating wells spanning over multiple layers; dramatically reduce run times when simulating models; leverage the power of your PC’s dual processor when simulating multiple species. Visual MODFLOW Premium* 4.3. is loaded with muscle to help groundwater experts deliver complex projects faster.
The industry standard in groundwater modeling now integrates new and enhanced features including the Multi-Node Well (MNW) package, support for MODFLOW-SURFACT 3, MT3DMS multi-processor support, improved Wells Manager, and two numeric engine updates. Give it a test drive by downloading a demo today.

First SWS Groundwater Research Lab in Mexico:
Researchers now have full access to the latest groundwater software in the industry
The inauguration of the first SWS groundwater research lab at the end of April was a complete success. Fully equipped with Visual MODFLOW Premium*, Hydro GeoAnalyst*, AquaChem*, AquiferTest Pro*, and Visual HELP*, the lab represents a major cooperative endeavor between SWS, the Water Institute of the State of Nuevo Leon, and ITESM – one of the best private universities in Mexico.
This lab is part of several key research labs created and directed by the Research and Innovation Park from the State of Nuevo Leon in an effort to raise the level of knowledge and research and development on many subjects, including water resources management. The combination of the ITESM and the Water Institute's top-notch applied scientific research and the cutting-edge SWS technology will dramatically expand knowledge amongst researchers and post-graduate students alike.

Westbay System used for remedial investigation of contaminated groundwater in fractured bedrock at Maryland Superfund site
Between 1962 and 1988, the present-day Spectron Superfund site in Elkton, Cecil County, Maryland USA was the location of Galaxy Chemicals/Spectron, Inc., a company that recycled chemical solvents and blended fuels. In 1988, after nearby residents complained of careless practices at the plant, the State of Maryland shut Spectron down.
Following geophysical testing and sampling of the borehole, the Westbay* System from Schlumberger Water Services was installed and data was collected from different intervals within the same borehole.

Schlumberger Water Services (SWS) Provides A Unique Water Quality Evaluation
Schlumberger Water Services (SWS) recently
demonstrated the ability to estimate future
impacts of acid tailing effluents seeping into a
river flowing in the valley below the mine.
Impacted river water mixed with a number of
downstream tributaries prior to the compliance
point for the mine.

Special Announcement
“Feasibility Study for Raw Water Supply to a Proposed Reverse Osmosis Plant on New Providence Island, Bahamas”
Paper to be presented at 20th Salt Water Intrusion Meeting (SWIM) scheduled June 23-27, 2008 in Naples, FL.
By Weixing Guo, Wm. Scott Manahan, and Thomas M. Missimer
Schlumberger Water Services, Fort Myers, FL, USA
ABSTRACT
A hydrogeological investigation was conducted to study the feasibility of raw water supply to a proposed reverse osmosis (RO) plant on New Providence Island, Bahamas. The study included field investigation and development of a SEAWAT model. After calibration, the model was used to evaluate the long-term water quality changes due to different withdrawal scenarios. Both wellfield and lake withdrawals were considered. The results indicate the raw water total dissolved solids (TDS) concentration would increase quickly due to vertical migration of salt from below. There is no significant difference to the simulated water quality changes between well or lake withdrawals.

Setting Up a Batch Run in Visual MODFLOW
Multiple projects can be run in the VMEngines interface of Visual MODFLOW. This is useful if you would like to run several different models at once and/or are comparing the results of similar models with slightly different parameters.
| To run your models in batch mode, each model must be translated first. Open each model separately and, in the Run menu, select the engines to run and translate the files. |
|
The numeric engine(s) available for the batch run will correspond to the last individual run of that model. If you would like to run additional engines that are not listed, you would need to open each model separately, go to the Run menu, select the engines to run from the dialog, then select translate.
| When each of the models have been translated you may start your batch run. Open one of the models in the batch run and open the Run menu. When running a batch of simulations, it is recommended to disable the VMEngines Auto Start feature (from the Engines to Run window): |
|
Select Run from the Engines to Run window.
In the VMEngines window, select File>Add Project and browse to each model (projectname.vmf) you wish to run. The selected projects will appear in the project tree.
You have the option to either run all simulations (in batch mode) by clicking
on the Start all Projects icon, or run the currently selected project in the
Project Tree by clicking on the Run project icon.
Please be aware that if a model fails to converge, user input will be required to clear any error messages before the batch run can continue.
If you would like to remove an engine to be run, you can manually delete engines from a project run by right-clicking on the engine and selecting Delete.
The Visual MODFLOW project files selected must be opened and translated by the current version of Visual MODFLOW before they can be added to the Project Tree.
Once the appropriate projects and engines have been selected, start the batch mode by selecting the Start all Projects icon. Visual MODFLOW will run all of the selected projects.
Open each project individually to view the results of the simulation. |
