Groundwater Flow & Transport Modeling with GMS
October 6-9, 2009 | Las Vegas, Nevada

Theory and application of geostatistics, site characterization, MODFLOW MODPATH,
MT3DMS, MODAEM, and model calibration.

Aquaveo will award 2.8 CEUs to each participant who successfully completes this
course.

COURSE DESCRIPTION
The groundwater modeling training course by EMS-I is designed as a hands-on,
application oriented training course. The course will provide the attendees with
the knowledge and tools necessary to solve groundwater modeling problems quickly
and efficiently. The course will begin with a discussion on how to use the
geostatistical tools in GMS to characterize existing contaminant plumes in both
two- and three-dimensions. A series of tutorials and lessons on the GMS
interface to MODFLOW/MODPATH/ MT3DMS/RT3D will then be given including an
explanation of how to use the Map Module to create numerical models directly
from a high-level conceptual model constructed with GIS tools. Analytic element
modeling with MODAEM will also be covered.

COURSE OBJECTIVES
Objectives of the four day training course on GMS are:
* Learn to build and calibrate groundwater flow models with MODFLOW
* Learn the basics of transport modeling with MT3D
* Analyze particle tracking with MODPATH
* Learn to characterize contaminant plumes in both 2D and 3D
* Use MODAEM to solve simple flow and particle tracking problems
* Learn to use GIS objects to create conceptual models
* Learn to calibrate groundwater models
* Learn how to generate professional output for your modeling projects
* Parameter Estimation with PEST
* Learn to build 3D stratigraphy from borehole and field data
* Benefit from hands on instruction throughout the course

The cost for the 4-day course is $1495.00 USD for pre-registration made at least

Dear Fanny,

You could try to make all layers type 3 (confined/unconfined, Variable S,T),
save the modflow
model and then import it in GMS. I am using an old version of Visual Modflow, if
you have
a newer one you might try to save your modflow model as Modflow2000, GMS should
be
able to read the .dis file.

Regards,
Jan

Hi,

I have just started working on GMS and I have some problems. I want to import
some Visual Modflow files to GMS but when I do it, I don't have the right
layers' elevation. My model has 9 layers but when I switch to "side view" there
is only one. Also, the elevation for all the layers (but layer1) are set to 0.
Can somebody tell me how to import the elevation from Visual Modflow?

Thank you,

Hello,
I have two problems :

1. Is Modflow solver is only for saturated/parially saturated zones.Means it
will not support simulation if initial head is less than bottom elavation of a
layer.

2. What is the significance of maximum stage in Lake package . My lake stage
during simulation crosses above this maximum stage. Why does it happen???

I am working with MODFLOW using GMS 6.0 interface.

PEST Courses and Conference 2009

Registration is open for the inaugural "DOUBLE-HEADER" SPRING PEST COURSE,
San Francisco, May 2009, comprising a two-day "Introduction to PEST" course
and a subsequent two-day "Advanced Analysis using PEST" course. The
introductory course is suitable to modelers with little to no experience
with inverse methods. This course will comprise about 50:50 lectures and
hands-on-exercises, with the aim of providing theoretical background on
least-squares inverse methods, and practical experience in their
implementation. In the advanced course the emphasis turns to highly
parameterized inversion in calibration of ground and surface water models,
and in exploration of the uncertainty associated with model parameters and
predictions. Topics covered in detail include the use of pilot points as a
parameterization device; advanced regularization techniques; the
"SVD-assist" technique for efficient inversion of highly parameterized
models; linear and nonlinear uncertainty analysis including the highly
expedient Null-Space Monte Carlo method that is unique to PEST. This course
will comprise about 80:20 lectures and hands-on exercises, with ample room
for discussion. Participants at either course will receive a CD containing
12 exercises to take away and study. Attendees can register for the
"Introductory" course, or the "Advanced" course, or both courses with a
discount on the individual course prices. Further information, including a
detailed course outline and registration details, is available at

just came across GMS Femwater lately.I like it very much. Found it
hard to setup a hypothetical saltwater intrusion into a single pumping
well. The tutorials dont clearly illustrate an example for it.Could I
get some specialists hand on this. I need it to demonstrate
capabilities of the software. So, it might be useful if help could
include the visualization of the results.

I would appreciate any help on this. Thanks and More Power to the group.

Dear Sir
How can I find SUB package of MODFLOW in Visualmodflow3.1
How can I calculate earth subsience of drawdown by VisualModflow3.1
sincerly yours

We would like to make you aware of session H75 "Decision-Appropriate
Modeling throughout the Lifecycle of Restoration, and other, Environmental
Projects" at this years AGU Meeting in San Francisco, December 15-19
(http://www.agu.org/meetings/fm08/index.php/Main/HomePage). The goal of this
session is not to discuss the mathematical details of model applications and
uncertainty analysis: rather, the goal is to discuss examples where models
have been both successfully and unsuccessfully applied in support of
environmental decision making, and attempt to elucidate the apparent reasons
for their success or failure. The conveners consider the following as
potential topics for discussion:

*         Simplistic versus complex models - Do the benefits of complex
models justify their use?

*         Deterministic or stochastic modeling? - Their pro's and con's for
decision making and for expert testimony.

*         Dealing with uncertainty - Rigorous evaluation vs. communication?

*         How can you tell a good model from a bad? - Is there no hope for
the decision maker to tell the difference?

*         Modeling objectives - Who sets them, are they realistic, and who
evaluates the results?

*         Collaboration with stakeholders - Best practices, new paradigms,
and future directions.

Abstracts for this session are due no later than September 10th, 2008:
please review the instructions on the following page
(http://submissions3.agu.org/submission/subm-ins.htm) regarding submittals.

We hope that you will be able to join us for some lively debate in December

SSP&A is excited to be able to host the following course in Bethesda,
Maryland (USA) this September, 2008:

"Building and Applying Analytical Element Models with Examples and Exercises
using Python"

Analytic element models are often refreshingly easy to understand, and
insightful. The best approach to learn the analytic element method is to
implement it in a simple computer program. This sounds daunting, but using
the Python language, it is possible for any hydrogeologist with a basic
understanding of the building blocks of a computer program. In this new
course, you will build your own analytic element model, and have a great
time doing it.

The course is taught by Dr. Mark Bakker. Mark has taught for 10 years at
American universities and now teaches at the Delft University of Technology
in The Netherlands. In addition, Mark is a consultant for Kiwa WR in Holland
and for WHPA in Bloomington, IN. Mark received his Ph.D. at the University
of Minnesota under the guidance of Prof. Otto Strack, the originator of the
analytic element method. Mark has written a number of analytic element
programs, of which TimML, the free, open-source analytic element model for
steady multi-aquifer flow is the most extensive. Mark has taught workshops
in Python for Hydrologists and used Python in his Computational Methods
class at the University of Georgia, where students were programming in
Python after a basic 2 hour lecture.

For further information on the course, please visit the following web page,
or write to matt@... :

Good Day !!!

You are invited to join "Yahoo! Groups - archydro" (ArcGIS -
Geographical Information System). This group aims to provide a forum
for exchange of ideas and experiences regarding application of GIS in
Hydrology and Water Resources; and use of ArcGIS software (in
general) and Arc Hydro (in particular).

Geographical Information Systems (GIS) are used to display,
manipulate and analyse spatial (map) data. ArcGIS (produced by ESRI)
is an integrated collection of software products for building a
complete geographic information system (GIS). There are three ArcGIS
desktop applications - ArcCatalog, ArcMap, and ArcToolbox. ArcCatalog
is the application for managing your spatial data holdings, for
managing your database designs, and for recording and viewing
metadata. ArcMap is used for all mapping and editing tasks, as well
as for map-based analysis. ArcToolbox is used for data conversion and
geoprocessing. Using these three applications together, you can
perform any GIS task, simple to advanced, including mapping, data
management, geographic analysis, data editing, and geoprocessing.
There are also server-based ArcGIS products, as well as ArcGIS
products for PDAs. Extensions can be purchased separately to increase
the functionality of ArcGIS.

GIS is a powerful tool for developing solutions for water resources
such as assessing water quality and managing water resources on a
local or regional scale. Hydrologists use GIS technology to integrate
various data and applications into one, manageable system. ArcGIS
with Arc Hydro gives you the flexibility to combine watershed
datasets from one map source with stream and river networks. The
suite of tools contained in Arc Hydro facilitate the creation,
manipulation, and display of hydro features and objects within the
ArcGIS environment. Use ArcGIS Spatial Analyst for hydrologic
analysis such as calculating flow across an elevation surface, which
provides the basis for creating stream networks and watersheds;
calculating flow path length; and assigning stream orders.

There's a seminal paper on fault flow in the Bighorn Basin (USA) by Bredehoeft
from the 1980's.

He used MODFLOW if I recall.

The real decision you need to make here is whether they are acting as barriers
against or conduits for flow.

I suggest a sensitivity analyses as well.

Dear all,

I am modeling a karst area; I have some faults in this area. I have some
monitoring wells around the faults. These monitoring wells supplied us with the
water level changes in the wet season and dry season for two years. Also we
considered it as observation wells in a pump test. I want to take the faults as
the boundary for the study area, so kindly I need answer for the following:

Is it possible to know the hydrologic condition for the fault, and calculate the
flux across it from these monitoring wells?

Can you supply me with names or website for any papers or reports, solving this
problem?

Thanks to all members

I agree with u Vevien, MODFLOW Manual is the most badly written manual where u
should not expect nething except function of each tab...

  None of the tutorials I've seen show how to do it and the Help information is
not very helpful either.

  Thanks Vivien

I think this is the problem that I too had a while back - I think it is because
your layer boundaries are not horizontal (no problem with that) and the river in
some places is in contact with one layer and other places it is in contact with
the next layer.

I think if you double click on the river arc and instead of <use layer range>
choose <auto assign layers using lower cells> this will assign the river arc to
the appropriate cells in the topmost layer that it crosses at all the points
along the arc.

Dear People
I'm really confused. I really need your help. Constantly getting this
error message when I do the modflow simulation check using GMS 6.0
"The Changing Head Boundary Condition is below the bottom elevation of
cell"

Now what I'm trying to do:

> made a 3D grids and new modflow model
> then interpolated the solid solids to modflow model (grid overlay)

using coverage to modflow comand

After that when I check simulation: it gives me above error. not sure
what is happening.

Any help would be appreciated.

Thanks, Zahid

hello sir,

i am using GMS for my work and my problem is that using MINLP solver
optimization, i want some examples for this solvers here binary varilable uisng
for one of the decision variable, like

yi=sum of (y1*binary variable1+y2*binary variable2+.......

so i need examples for that problem sir,

plse help me out this problem........ for solving my minlp
problem...

                thanking you
