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@... :

Registration will be limited to 12 attendees. A block of rooms has been
arranged at a nearby hotel for course participants - details are provided on
the web page.

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

All,
I have been trying to use the observation process in SEAWAT 2000.
The model runs fine, but I do not get anything meaningful from the
observation process output files.  I have checked to see if it is my
OBS or HOB input files by running the model in MODFLOW 2000 which
results in meaningful output files.  I have also checked the binary
head file output by the SEAWAT model and find it to contain the
correct heads.  It is just the heads that are output through the
observation process (the `*._os' file) that aren't accurate.

Has anyone encountered this problem before?  Has anyone been able to
successfully use the Observation process in SEAWAT 2000?  Any idea as
to what is causing the issue?

I have the Observation process set up to calculate heads at
monitoring wells during a pumping test (i.e. the model is
transient).  In the `*._os' file, the first predicted head value for
any monitoring well is shown as some number not zero and all other
predicted head values for other times at the given monitoring well
are reported as zero.  The same OBS and HOB file work fine when
running just MODFLOW 2000, it is when I try and run the model using
SEAWAT that this problem occurs.

I'm not familiar with how VMOD PRO 4.2 writes the SEAWAT input files,
but I have had similar issues when the time information in the DIS
(MF2K) input file does not match the time information in the BTN
(MT3DMS) input file.  Try matching the time information in those two
files.

Hope that helps.

Greg

Re: Modelling of seawater intrusion
Monday, September 22, 2008 3:52 PM
From: "alessandro.casasso" <alessandro.casasso@...>
To: "C. P. Kumar" <cpkumar@...>

Have you found any answer to you questions? I'm working at a MS thesis about
Feflow modelling of a shallow aquifer in Venice. I will not try to model salt
pans - too difficult even to think where they are.

About rainfall and evapotranspiration: I've got rainfall and temperature data. I
calculated ET with Blaney-Criddle formula, but I found that results are
overestimated. I tried to reduce risults by comparing modeling results with real
results (in the area I'm studying, I can get results from 11 piezometers..) and
I found that BC formula results can be divided by 3. I found that ET estimation
is one of the most difficult parts of shallow aquifers modeling...

I've got no idea about brackish water in rivers. In my model, I assigned the
tidal oscillations (1st type boundary conditions) also to a channel of Venice
lagoon that encloses my modeling domain.

I developed a relation between TDS and conductivity (I've got specifical
conductivity measures), but I did a very rude approximation. As I'm modeling a
peninsula, I thought that seawater contains most NaCl , so conductivity
(microSiemens per cm) is dominated by NaCl concentration. Conductivity is linked
to NaCl concentration in this way: - every ion has an equivalent conductivity,
that is the specifical conductivity for a concentration of 1 equivalent/liter
(for NaCl, 1 equivalent = 1 mole); - this equivalent conductivity is also linked
to concentration by Onsager formula; - specifical conductivity = equiv conduct x
concentration [mole/liter]

I visited your site some time ago, I found it very interesting. Sorry for my
English, I have to improve it. About my tip on TDS-conductivity: as we say in
Italy "here I tell it, and here I deny it" :-) I'm only a MS student and I got
these advice reading a laboratory chemistry manual...

See you soon on this forum,
Alessandro Casasso

Dear Group Member,

I am grateful to the following members/experts for their interesting/useful
observations/comments/suggestions on my report "Modelling of a Coastal Aquifer
using FEFLOW" (available at ftp://ftp.wasy.de/FEFLOW/Goa.pdf ).

(1) Reinhard Zapata (Waterloo Hydrogeologic, Canada)
(2) Krishnaiah C. (India)
(3) S.V.N.Rao (Roorkee, India)
(4) V.V.S. Gurunadha Rao (Hyderabad, India)
(5) Michael Jorgensen (Australia)

I am prompted to seek further suggestions for the following issues in modelling
the seawater intrusion in coastal aquifers.

(a) How to model the effect of salt pans on groundwater in coastal areas?

(b) How to incorporate the evaporation from open water surfaces (e.g. to define
time-variant boundary condition in case of rivers) and evaporation from shallow
groundwater table?

(c) How to model the effect of brackish water in rivers (due to tidal backwater
effect from sea) on groundwater in coastal areas?

(d) How to develop correlation between resistivity values and TDS and between
resistivity values and hydraulic conductivity.

(e) Suitability of Kriging, Akima and Inverse Distance Weighting techniques for
interpolation/regionalization of different parameters/variables.

Any suggestions for the above will be helpful for extension of this (or similar)
study in future.

There is a small errata in the report - title of figure 7 may be read as
"Measured Values of Hydraulic Conductivity (*10E-4 m/s)" - the multiplier was
missing.

Hi,

I downloaded SEAWAT to evaluate. I am looking for a groundwater model that
integrates
solute transport in ground water. I know I can use the MT3DMS model along with
MODFLOW,
but if SEAWAT already integrates those two then is it safe to assume that SEAWAT
is
appropriate for solute transport in river systems. I simply want to obtain info
about river flow
and solute concentration in the river at a given location.

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
"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.

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

Hi,

Does anyone know where I can find some literature values for the diffusion
coefficient for saline water in an aquifer? I have searched and found very
little, only conflicting information. The tutorial tells you to use 10^-10 m2/d,
but the manual (older version) which discusses Henry's problem says that they
used 1.62925 m2/d. They are obviously many orders of magnitude different, which
is worrying!

Also, is it possible to change the diffusion coefficient once you have set up a
transport variant in SEAWAT? The option is there under the species parameters
when you first apply the values, but if you return later the option is no longer
on the list. Do I have to add a new species from scratch or is there a quick
way?

Thanks,

Matt

I have a potential source for the diffusion coefficient, but still wondering
about the SEAWAT problem!

Thanks,

Matt

Diffusion coefficient for Henry problem is actually the total dispersion
coefficient.  Henry assumed a constant dispersion coefficient (D) to obtain
his semi-analytical solution.  You will notice that the dispersivity values
are 0 for the Henry problem.

The PEST Conference is fast approaching! The 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 goal is to bring together modelers from a variety
of disciplines to discuss parameter estimation and uncertainty analysis and
seek input to guide future 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 from
a noted modeler. Over thirty presentations covering topics from
highly-parameterized groundwater modeling to integrated
surface-water/groundwater model calibration will be summarized in electronic
proceedings distributed on thumb drives. The conference will wrap with a
question-and-answer session during which attendees can ask questions and
provide suggestions for future development. Keynote speakers include John
Doherty (developer of PEST), Ghislain DeMarsily (developer of the Pilot
Point technique: appearing via video-conference), Jim Rumbaugh (ESI,
developer of Groundwater Vistas), Jasper Vrugt (Los Alamos National
Laboratory), and Randy Hunt (US Geological Survey). "Introductory" and
"Advanced" PEST Courses will be held prior to and following the Conference,
respectively.

Call for Papers : Special Issue on Probability Distributions and
Frequency Analysis (PDFA)

OBJECTIVES:

The objective of frequency analysis in a natural context is to infer
the probability that various size events will be exceeded or not
exceeded from a given sample of recorded events. Two basic problems
exist for most natural applications. First the sample is usually
small, by statistical standards, resulting in uncertainty as to the
true probability. And secondly, a single theoretical frequency
distribution does not always fit a particular data- type equally well
in all applications. Regionalizing the probability distributions could
improve the at-site estimates and estimate the future events for
ungauged sites. The interaction between sites and also the variables
is of interest for further research

This special issue would attempt to bring the new developments in
Probability Distributions and Frequency Analysis and the applications
in diverse environments.

TOPICS:

Topics include but are not limited to:

1.       Frequency Analysis of Natural Events: Flood, Droughts
(agricultural, meteorological and hydrological), Low Flow, Rainfall,
Wind Speed, Waves and Water Level, Water, soil and air pollution,
Earthquake, Landslide volumes, Vowels.
2.       New Development s in Probability Distributions (including
parametric and non-parametric approaches)
Joint, conditional and mixed Probability Distributions (e.g.
copula-based approaches), Higher Moments, Probability Weighted
Moments, L-moments and Recent Developments.
3.       Probabilistic  Based Methods: e,g. Probabilistic Neural
Network, Probabilistic Rational Method.
4.       Regionalization and Probability Distribution.
5.       Wavelets and Time-Frequency Analysis Technique
6.       Probability Density and Spectrum


SUBMISSION INFORMATION:

The manuscripts should be submitted to one of the issue Guest Editors
with a covering letter. It is recommended to send the pdf version of
the paper. All manuscripts will be subject to peer review. If finally
accepted, the articles must be formatted by the authors according to
"Author Instructions" of the journal
(http://ceser.res.in/ijamas.html).


IMPORTANT DATES:

Deadline for Full Paper Submission: 31 May 2010
First Round of Paper Review Notification: 31 July 2010

Hi Lee.

I am also new user of SEAWAT, I am trying simulate saltwater intrusion too by
visual MODFLOW Premium.  I was told that the grid size and the time step should
be appropriate. I think that may be you try to check this way.

I do not have this problem, but I have a problem in input the sea boundary in
this model. If you have any example how to input this boundary in SAEWAT 2000
engine, please, help me, I will be gracefull.

Thank you,
Cheers
Phuong

Hi:

Registration is open for a Double-Header PEST course, comprising a two-day
"Introduction to PEST" course and a subsequent two-day "Advanced Analysis
using PEST" course.

Lessons will be taught at the CERI Research Center, in Valmontone

(30 km SE of Rome, Italy), connected by highway and trains to Rome

The Introductory course is most suitable to modelers with little to no
experience with inverse methods. This course will comprise a balance of
60:40 lectures and hands-on-exercises, providing theoretical background on
least-squares inverse methods, and experience in their implementation with
environmental models. This course will include groundwater modeling
examples, together with other environmental modeling applications. The
Advanced course emphasizes calibration of highly parameterized ground and
surface water models, and explores the uncertainty associated with model
parameters and predictions. Topics covered in detail include pilot points;
advanced regularization techniques; the "SVD-assist" technique for efficient
inversion of highly parameterized models; linear and nonlinear uncertainty
analysis including the Null-Space Monte Carlo method; and methods for
optimizing data acquisition to reduce uncertainty. This course will comprise
a balance of 90% lectures and 10% hands-on exercises, with ample room for
discussion. Participants in either course receive a CD containing hands-on
exercises to study at their leisure.
Further information, including a detailed course outline and registration
details,

is available on
