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
http://www.sspa.com/Pest/training.shtml
Registration is open for THE INAUGURAL PEST CONFERENCE, to be held in The
Stained Glass Hall of the Bolger Center, Maryland, USA (
http://bolgercenter.dolce.com/ <http://bolgercenter.dolce.com/> ) November
2nd through 4th, 2009. The objective of bringing together modelers from a
variety of disciplines is to exchange ideas, discuss applications of the
PEST suite of programs, share lessons learned, discuss new and planned
developments, and seek input from modelers on inverse modeling needs to
guide future code development with a focus on PEST (www.sspa.com/pest). The
Conference will commence with a message from John Doherty, the developer of
PEST. This will be followed by morning and afternoon sessions, commencing
with a key-note address by a noted modeler, followed by submitted
presentations and a poster session. Submissions will be summarized in
extended abstracts and/or full papers published in electronic proceedings.
The conference will wrap with a question-and-answer session. Keynote
speakers include John Doherty (developer of PEST), Ghislain DeMarsily
(developer of the Pilot Point technique), Jim Rumbaugh (ESI, developer of
Groundwater Vistas), Jasper Vrugt (Los Alamos National Laboratory) and Randy
Hunt (US Geological Survey). A one-day "Introductory PEST Course" will be
held immediately prior to the conference, and a two-day "Advanced PEST
Course" will be held immediately following the PEST Conference, with
instruction from John Doherty, Jim Rumbaugh, and Matt Tonkin. Details
including information on abstract submissions, early-bird discounted
registration, accommodations, and the pre- and post-conference courses can
be found at www.sspa.com/ThePESTConference.

dear group,
started learning groundwater modeling. To begin modeling, I need initial
condition. I know the following:
- observation well data
- one river stage and bottom data taken at older date than the observed head
data
with measurements taken from different period (river information in 1998 and
observation head information is in 2004
How can I use the initial conditions for a steady state simulation ?
On behalf of John Doherty, Jim Rumbaugh, and myself, please consider joining
us at the first-ever PEST conference! This will be held in The Stained Glass
Hall of the Bolger Center, Potomac, Maryland (
<http://bolgercenter.dolce.com/> http://bolgercenter.dolce.com/) November
2nd through 4th, 2009. The goal is to bring together modelers from a variety
of disciplines to discuss the use of inverse modeling techniques - i.e.,
parameter estimation and uncertainty analysis - with a focus on the PEST
suite of programs, and seek input from modelers on inverse modeling needs to
guide future code development. The conference will commence with a message
from John Doherty, the developer of PEST, and will follow with morning and
afternoon sessions, each commencing with a key-note address given by a noted
environmental modeler. A poster session will be held one evening. Oral and
poster submissions will be summarized in extended abstracts and/or full
papers, published in electronic proceedings distributed on thumb drives. The
conference will wrap-up with a question-and-answer session during which
attendees will be able to ask questions and provide suggestions for future
development directions. Keynote speakers include John Doherty (developer of
PEST), Ghislain DeMarsily (developer of the Pilot Point technique), Jim
Rumbaugh (ESI, developer of Groundwater Vistas), Jasper Vrugt (Los Alamos
National Laboratory), and Randy Hunt (US Geological Survey). A one-day

On behalf of John Doherty, Jim Rumbaugh, and myself, please consider joining
us at the first-ever PEST conference!
This first-ever PEST Conference will be held in The Stained Glass Hall of
the Bolger Center, Potomac, Maryland ( http://bolgercenter.dolce.com/
<http://bolgercenter.dolce.com/> ) November 2nd through 4th, 2009. The
primary goal of the PEST Conference is to bring together modelers from a
wide variety of disciplines who either have experience in, or would like to
learn more about, the use of inverse modeling techniques - i.e., parameter
estimation and uncertainty analysis - with a particular focus on the PEST
suite of programs (www.sspa.com/pest ). The objective of bringing together
modelers from a variety of modeling disciplines is to exchange ideas,
discuss applications of the PEST suite of programs, share lessons learned,
discuss new and planned developments, and seek guidance from modelers on
inverse modeling needs to guide future code development. It is also hoped
that this forum will provide an opportunity for modelers to meet and discuss
novel approaches that they have taken to solving problems that they have
encountered.
The PEST Conference will commence with a message from John Doherty, the
developer of the PEST programs. John will provide some history of the
development of PEST, discuss wide ranging applications of PEST, outline
planned future developments, and doubtless wax lyrical on a great many other
topics! The conference will follow with morning and afternoon sessions, each
commencing with a key-note address given by a noted environmental modeler,
followed by submitted oral presentations. A poster session will also be held
one evening. Oral and poster presentations will be summarized in extended
abstracts and/or full papers that will be published in electronic
proceedings distributed on thumb drives. The conference will wrap up with a
question-and-answer session during which attendees will be able to ask
questions of the organizers and of John Doherty, in particular, and provide
suggestions for future development directions.
A one-day Introductory PEST course will be held immediately prior to the
conference, and a two-day advanced PEST course will be held immediately
following the PEST Conference, with instruction from John Doherty, Jim
Rumbaugh, and Matt Tonkin.
Further information about the PEST Conference - including the list of
keynote speakers and information on registration, accommodations, and
travel, will be posted soon at www.sspa.com/ThePESTConference.
We hope to see you in November 2009!

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,

Thank you for your help. Actually, I want to make the number of cells
bigger with smaller cell size (finer mesh).
BTW, do you know how to modify the position and the depth of a well
or even remove it?
Thanks again

If you want to keep the same number of cells, than you should use the
grid editor tool. go in grid, edit colomn or row spacing and assign
the new value for the row and colomns you want to change.Calculate
the length and width lost on your grid and divide it by the number
of colomns or rows you have not changed, and then add this value to
the spacing of each unchanged colomn and row to compensate for the
gap created.You will have a grid the same size with the same number
of rows and colomns. Easiest and fastest way (to my knowledge), Hope
this could help.

Hi everyone,
My name is Lee. I've just started learning how to use groundwater
vistas. I don't know if there is a quick way to discretization. For
example, I want to split cells into half, do I need to go to each cell
and then insert column/row/layer. It takes so much time.
Any assistance would be greatly appreciated.
Many thanks,
Lee
I try to simulate the drawdown in a double aquifer model. The well is
pumping in the confined aquifer using the MNW package. It is a
partially 3D model and I am using the LPF package to represent the
confining unit. I face difficulties to have proper results and to
represent the leakance in the aquitard. I don't see changes in results
when changing the leakance value (Kz of the aquitard), but when I use
the option Kz of layers, the input value of leakance has an effect on
heads values in both aquifers. As I am new with modflow,and I am not
well conversant with the input logic of Gvistas,could you help me
giving me exemples of possible mistake .Thanks for your time and
comprehension

Dear Sir/Madam,
I believe that,underground water gets enriched by the rain water entering some
of the cracks on the crust of the earth.
Such cracks might have been filled by soil now and may not be visible to our
naked eye. I want to identify with the
help of satellite picture (may be by using any modern technology like infra red
photos) the cracks on the earths crust.
Once we identify such spots, we need to construct water harvesting/storage
systems next to such spots with an
intention to help the rain water reach such cracks and enrich deeper part of the
earth quickly. Thus, the rain water
gets recharged quickly resulting in improvement of underground water table and a
lot of benefit. For this project,
I want to know where can I get the satellite images which may give me idea
about the spots which has got cracks
on earths crust.

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.
To subscribe this group, please send a blank email to
archydro-subscribe@yahoogroups.com
Apologies for cross-postings.

Dear all,
I am now set up a model by GW vista Version 4. when I want to assign wall by
polyline method, it comes out: You may not digitize HFB (slurry wall) locations.
How can I sort out this problem?
The other one is I can run my model in MODFLOW 96 package, but I can not run
it in MODFLOW 2000. I found that when I create the datasets for MODFLOW 2000,
there are not datasets created. I know DIS file is require by MODFLOW 2000. I
try to re install the software, but it does not work.
Anyone can give me some tips? Thanks very much
Peter
Matt:
I am sorry to hear about John, but glad you told me now. I was planning to
bug Jinhui about making travel arrangements. Wait, you know what? Charlie
has indicated that he wanted to get Jinhui down to get him into our network,
so to speak. So maybe I will press him to make travel plans, PEST course or
not.

Dear members:
I wish to apologize for the somewhat off-topic correspondence between myself
and my colleague Chris that appeared on the GWV list tonight. We have for 13
years held an ongoing dialogue regarding the relative ease (or otherwise!)
of various programming languages, since we often default to our old favorite
Fortran, and this dialogue spilled onto the GWV list tonight. Despite my
stubborn adherence to Fortran I look forward to learning to program the AEM
method using Python in the course to be given by Dr. Mark Bakker and may yet
be convinced to change my die-hard Fortran ways!
Sincere apologies, and end of off-topic discussion:

SSP&A is very 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 very
insightful. The best approach to learn the analytic element method is to
implement it in a simple computer program. This may sound daunting, but
using the easy and powerful Python language, it becomes possible for any
hydrogeologist with just a basic understanding of the building blocks of a
computer program. In this new course, you will actually 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 his home country of 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.

I concur, w/Mark -
Jim provides by far the best technical support I have ever had, far superior
than WHI's Visual MODFLOW. The main difference is that Vistas does so much
more. As such the layout is more "complicated" than Visual which has a simple
layout but does far too little. Although you should realize that Vistas is not
big on 3D animation. I think this is where Visual exceeds Vistas. Jim will
answer any questions you may have. He has a trouble shooting manual, but
honestly if you are not sure take one of his 3-4 day classes they are excellent.

Has anyone heard of a training manual for GV other than the one
included with the software package (which was written by Jim and his
brother)?
Thanks,

Dear Member,
Can you please refer me to any relevant literature (case
studies/papers/web resources) pertaining to unsaturated and saturated
groundwater flow modelling to study the impact of rainwater
harvesting structures and artificial recharge structures on
groundwater system.
My apologies for cross-postings.
Thanks & Regards

A 3 day PEST course will be held in Bethesda, Maryland, USA, the week of
April 7th, 2008. Recent PEST development has focused on stabilizing the
inverse problem for highly-parameterized models and evaluating model
predictive error. In doing so, the methods embodied in PEST take into
account the null space contribution to potential predictive error. All
course participants will receive a CD with a seven comprehensive PEST
workshops. Participants will also receive the latest version of PEST and all
of its support utilities. The workshops show how to use these utilities. For
more information on the course, including registration, please visit the
following web page.
http://www.sspa.com/pest/training.html
Current course registration fees reflect a 10% "early-bird" registration
discount available through January 31st, 2008. Fees will rise to the full
rate February 1st, 2008. Please write to pest@... with any questions
about the course.

Hi everybody,
I am learning GW Vistas and I want to have access to more learning
resources beyond the material you can find in the program tutorial.
Do you know if there are further learning resources somewhere else?
Thanks in advance
XAVIER
Hi Does anyone have a model in Vistas Verion 4 or 5 that runs SEAWAT?
I have the opportunity to do some SEAWAT modeling. I have done quite a
bit w/MODFLOW and MT3D but have not spent time learning SEAWAT, so I
thought if I could get me hands on a running model I could gleam what I
need from the model to set up my own.
If any one can be of assistance it would be greatly appreciated. This
could also include any tutorial that may be available.
Mike
Hi: This is a brief email to make some announcements related to the PEST
freeware:
September Course, Copenhagen, 2007: Spaces are still available for the 1.5
day PEST course before the MODELCARE conference, in Copenhagen, Denmark,
September 8-9, 2007. All course participants will receive a CD with a seven
comprehensive PEST workshops. Participants will also receive the latest
version of PEST (Version 11.3 described below) and all of its support
utilities. For more information on the course, including registration,
please visit <http://www.sspa.com/pest/training.html>
http://www.sspa.com/pest/training.html or write to <mailto:pest@...>
pest@....
Release of PEST version 11.3: The new version of PEST includes many new
additions including many new utilities; such as JACTEST, which makes it easy
to check the integrity of derivatives computed for a model; two global
optimizers (CMA and SCE), both of which can be used interchangeably with
PEST and both can undertake model runs in parallel for maximum efficiency;
programs that implement a new "null space Monte Carlo" technique for
nonlinear uncertainty analysis; and FORTRAN 90 modules (including source
code) that allow you to write software which communicates with a model like
PEST does, and to parallelize model runs.
See the PEST web site at <http://www.sspa.com/pest>
