Hi

Does anyone have a tutorial for GW Vistas on SEWAT?  I am familiar
w/MODFLOW and MT3D but have not spent time reading up on SEAWAT, yet I
have the opportunity to do some work using it.  If anyone has such a
tutorial or model that they can share w/me I am sure I can figure it
out from there.

Thanks,

Mike

Sir/Madam

I have simulated the flow in MODFLOW from 1992 to 2001.
I have water quality data for 1994,1997,2002,2004.
How to incorporate it in SEAWAT FOR FLOW & TRANSPORT modeling?

R.M.Das.

Hello everybody


I just started with seawat, but i  have no idea how to set the data,
when i have a modflow that works properly and also a mt3d that works,
how can i initiate with seawat? is taking me some time to understand this.

thanks for your time and patiente


fredy.

Greg,

Many of the newer features in MODFLOW and it's variants do not carry
forward observations. For example I have to run a little post-processor to
create OBS for subsidence that are interpolated to observation times.
Similarly we are in the porcess of creating an OBS routine for the linkage
on MODFLOW-LGR with MODPATH. Similarly we have created time series for
most of the flow components generated for the new Farm Process but they
would still require interpoaltion in time if comparisons at time frames
more detailed than time steps is required. But I agree that it would be
beneficial if the OBS were available for these and other newer attributes
and HYDOMD does create much of this functionality.

Cheers,

Re: [seawat] HYDMOD






Randy,
I came across HYMOD the other day and thought how useful it could be for
me when running SEAWAT because the OBS process isn't compatible with the
variable density flow capabilities of SEAWAT.  I am interested in
hydrographs (head or drawdown) in batch mode using SEAWAT 2000 and am thus
hopefull that the HYDMOD functionality isn't lost in the conversion from
MODFLOW 2000 to SEAWAT 2000.
Thanks for the reply and hopefully I'll hear from Chris over the next
little bit.

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@...>

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.

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.

your project is interesting. Probably you may use Matlab as a model building
tool. Once you have neural network toolkit with your matlab the rest is just the
application of your logic and common sense. To have a successful model run you
have to have a historical data on the river water quality, however your work may
not be that accurate unless you have a fairly long term data with you. So it is
critical in your work that you get as much historical data as possible, to set
your predictive trends.

it is quite possible that the river water quality doesn't remain consistent over
the year and changes seasonally or diurnally. So it is important to have a first
look at the water quality trends of hte river before you start building your
model and apply neural network.

I may assist you if at some stage you may require the combination of Neural
Network with Genetic Algorithm especially when you need to fine tune and
optimize your feeding parameters.

For you information I have developed a model using Genetic Algorithm for the
optimization of water quality monitoring stations in water distribution systems.

So as the first step you share the historical data and from there on we can
decide how to develop your model and integrate the tools available in Matlab.

Dear Member,

I am pleased to inform that I have recently completed
the study "Modelling of a Coastal Aquifer using
FEFLOW". A brief introduction of the study is given
below.

Coastal tracts of Goa (India) are rapidly being
transformed into settlement areas. The poor water
supply facilities have encouraged people to have their
own source of water by digging or boring a well.
During the last decade, there have been large-scale
withdrawals of groundwater by builders, hotels and
other tourist establishments. Though the seawater
intrusion has not yet assumed serious magnitude, but
in the coming years it may turn to be a major problem
if corrective measures are not initiated at this
stage. It is necessary to understand how fresh and
salt water move under various realistic pumping and
recharge scenarios. Objectives of the study include
simulation of seawater intrusion in a part of the
coastal area in Bardez taluk of North Goa, evaluation
of the impact on seawater intrusion due to various
groundwater pumping scenarios and sensitivity analysis
to find the most sensitive parameters affecting the
simulation.

For the study, a finite-element model (FEFLOW) was
used for model simulations. The FEFLOW is an
interactive finite element simulation system (Version
5.1) for three-dimensional (3D) or two-dimensional
(2D), i.e. horizontal (aquifer-averaged), vertical or
axi-symmetric, transient or steady-state, fluid
density- coupled or linear, flow and mass, flow and
heat or completely coupled thermohaline transport
processes in subsurface water resources (groundwater
systems).

Salient conclusions of the study are given below.

(1) Presently, seawater intrusion in Bardez taluk of
North Goa is confined only upto 290 m from the coast
under normal rainfall conditions and present draft
pattern. It may slightly extend farther for low
rainfall years.

(2) Seawater intrusion may further advance inland if
withdrawals of groundwater by builders, hotels and
other tourist establishments continue to increase in
the coming years.

(3) Groundwater salinity needs to be continuously
monitored near the coastal area, especially within 2
km from the coast.

(4) Corrective measures with proper planning and
management of groundwater resources in the area need
to  be initiated so that it may not turn to be a major
water quality problem in the coming times.

(5) The model is very sensitive to hydraulic
conductivity and dispersivity values. Field and
laboratory investigations need to be undertaken for
measurement of these parameters for use in further
modelling studies.

(6) The study will guide in making management
decisions to monitor and control seawater intrusion
and planning of groundwater development in the area.

I can send the complete report (in pdf format) by
e-mail to the interested persons. Your comments or
suggestions are welcome.

I had done the work with PM pro using the package modflow+density By Kiwa it
works fine for my case. There is not much written about this package in the
manual.
   regarding the SEAWAT I had tried before to us it but I got difficulties.
   I found another package which is good and I use it named SWI (by Bakker) the
problem with this software that you can't read the out put only if you use Argus
One and I don't have it. You could use Model viewer free to see the animation
but not to read the results.
   My question been regarding PM pro using the package modflow+density By Kiwa
but all replies get to me about SEAWAT.

Hello,

I am having issues with using a General Head Boundary condition at a
shoreline. We are simulating the tide rising and falling, however once
the cells on the shoreline go dry (low-tide) the cells are not re-
wetting. I wondered if anyone had seen this happen with GHB before.

software from  <http://www.sspa.com/PEST> http://www.sspa.com/PEST.

Why don't you use the PM win with SWI package they do support you with very good
manual and much easier to use. I start working with SEAWAT and PMwin but I found
that it is much faster and easier to use the SWI package with the PMWIN.

SWI is available for free with an excellent manual and very good examples. The
advantage of using SWI is that you can simulate the aquifer layer as single
vertical cells but seawat you need to do it at 10 layers which will required
much more work and data. Also SWI package deal only with the surface of the sea
fresh water intrusion without the need to run MT3D it dose not deal with
desperation and diffusion.

does anybody has a guidance listing the modifications one has to make
when using PMWIN as a preprocessor for SEAWAT? a list with special
hints to be considered would be appreciated.
thanks

Hi,

There is an easier package SWI with a very good manual you find it
and can download it free from http://bakkerhydro.org/ there is some
very good examples.

		 Calibration and Predictive Uncertainty Analysis Using PEST,
		 Minneapolis, Minnesota, April 16-18, 2007.

		 Watermark Numerical Computing will conduct a three-day short
course in Minneapolis, Minnesota.  The instructors will be Dr. John Doherty,
the author of PEST, Matthew Tonkin (SSP&A), and Dave Dahlstrom (Barr
Engineering Company). Course Pricing includes a 10% discount for early
registration (before March 1, 2007). A block of rooms has been reserved at
the very comfortable LeBourget Hotel in Bloomington, MN.

		 This intensive short course will instruct participants on
the automated calibration of environmental models, and on the analysis of
the predictive uncertainty associated with such models.  The principal
instructor is the developer of PEST, the industry standard software package
for model-independent, automated calibration and predictive uncertainty
analysis.  This short course will focus upon the use of PEST, including the
new capabilities added to Versions 9 and 10.
		 What you will learn
		 The course will include a thorough coverage of the theory
and applications of nonlinear parameter estimation techniques in the
calibration of different types of models. There is also a strong practical
aspect of the course.  Participants will gain hands-on experience in the use
of PEST, including its advanced regularization and predictive analysis
features. Experience will be gained in the use of these features in the
calibration of groundwater flow and transport models, surface water quality
and quantity models, as well as other types of models including a vadose
zone model and a biological growth model.

		 Course Details and Registration
		 For more details about the course, travel arrangements, or
