Hello--I am trying to identify groundwater training courses in FY08 for my performance assessment group who perform environmental risk assessments for...
Hi Cynthia, In case you're still considering FEFLOW for your modeling work: We will run a number of training courses next year, probably also in the US. On...
Hi Cynthia, Regarding your inquiry about groundwater training courses in FY08: We will be offering a three-day course on aquifer testing in San Antonio, TX,...
Waterloo Hydrogeologic, Princeton Groundwater Course, ESI may offer alternatives. Perhaps the USGS still does training (check with the National Research...
The International Groundwater Modeling Center (IGWMC, http://www.mines.edu/igwmc/ ) offers periodic training on various modeling topics. Also, the National...
Query 1. while doing transient state calibration if it is mendatory to mention steady state in time step option? If not mentioned the RMS goes high. Plz...
Hi Cynthia: In reply to your recent inquiry about upcoming ground water courses, listed below is the Spring 2008 course list from MIDWEST GEOSCIENCES GROUP....
There is a user's manual that comes with Visual Modflow, or you can take the training class, which I think costs $1,695 for a four-day intensive course, as per...
Hi, Folks: The Visual MODFLOW users manual describes the GUI for pre/post-processing the MODFLOW simulation (in addition to the other simulators, such as...
At the risk of being immodest, S.S. Papadopulos & Associates, Inc. makes freely available some pretty good MT3D technical notes that supplement the...

Hi Folks, I am using modflow96 code. The modflow model declares a globle variable X to store the variables that are referecned globly, e.g., HNEW, HOLD,...
HNEW is the only double precision array and that is why it needs to be declared. HOLD etc are single precision defaults so they do not require explicit...
thanks, Sorab. However, when HNEW is declared within the subroutines, the values of X(LCHNEW) cannot be transferred to HNEW array correctly. The HNEW elements...
I'm Trying to model thin, high hydraulic gradient system with VModflow. But the convergence is very difficult and dry cells are often the biggest problem. Can...
Hi Folks I am using Pest to calibrate a GW flow model. Actually I've already used Pest to calibrate other models quite succesfully. But this time, Pest stops...
I never noted anything like what your describing while debugging the program, so I think this may be a problem with your compiler. *Pete Sinton* *Principal...
Probably you need to check the format and the data in the file "targpest.out". Make sure the file is in the right place and both the data and format are ...

That is a message that usually means the run bombed after Pest created the model input files. And since it mentions targpest.out, it must be a Groundwater...

Probably the most common problem encountered with modflow. The solution depends on your grid, material properties, boundary conditions, what solver your...
I think you need to make sure the file existed. I had the same problem sometimes ago, if the file is not existed, then one of the reason could cause it is...
Maybe you should try John Doherty's revised MOFFLOW 96. Regards Jinhui From: gwmodel@yahoogroups.com [mailto:gwmodel@yahoogroups.com] On Behalf Of pjvleal ...
One way to avoid the convergence and dry-cell problem is to define the model layer as confined, but use a storage coefficient appropriate for an unconfined...
defining a cell as confined does not mean the cell cannot become dry *Pete Sinton* *Principal Hydrogeologist* *AquaGeo, Ltd.* 11560 Penny Rd Conifer CO 80433 ...
other approaches should be implemented before a re-wetting "fix", but Doherty's re-wetting function would probably do a better job in the case of re-wetting...
In MODFLOW, defining a layer as confined does prevent all active cells in that layer from going dry, as Walter says. And the approach he suggests is...
OK. I got that one wrong! But my experience is with situations where fixing the saturated thickness of a clearly unconfined system would not be possible. Its...
