Subject:: How to place a multilevel monitoring well in Visual MODFLOW 2.8.2???
toe_jambr
Offline Offline
Send Email Send Email
 
Is there anyone whom may help me in placing a multilevel monitoring
well in Visual MODFLOW 2.8.2???

My problem is:
#1   I choose Head Obs.
#2   I set two observation points: raso (shallow) and profundo
(deep),
and their respective depths, 8.5 and 11.7 meters.
#3   I set the head observed after 30 days, but just for one of the
depths I'm observing.


It appears to me I may be missunderstanding few concepts like
'monitoring well' and 'observation point', or entering information in
the wrong window, then there would be a window for static heads, and
this window (Head Obs.) would be useful for pump tests but not for
static heads, or I must add two different observation wells in the
same
location, with two different observation point depth, and two
different
head after the same 30 days.


Sorry about my poor english.


Thanks in advance,


Samuel Siqueira.

Dear,

Hello!

  I am working on ground water modeling using software Visual Modflow
V2.8. We are facing a problem while importing data. We have 5 pumping
test data and while importing transmissivity/well depth value
(unloading arc/info point coverage) but the software is not
interpolating (Inverse Distance Weighted) the data for the entire
grids. Please guide us in this matter.

With regards,

Suparn Pathak

PS. We also tried interpolating it outside and feed as .GRD surfer
format but failed.

You may only rotate the model domain during model setup, i.e., when you
build your model. You may do it by specifying a base map when you define
your model grid. This step will enable to rotate, align, or resize your grid
over the base map. Rotating the grid may be done using the rotation icon in
the Select Model Region window or specifying a rotation angle. I have never
had problems using this feature. Please let me know if this is not the

Hi Bruce,

   I advise you to have a geological cross section as well.

   From c/s:
   - First, differentiate between aquitards and aquifers.
   - Join similar geological layers (aquifers and aquitards) into a single layer
called  hydrostratigraphic unit or layer.
   - Try reducing layers.
   - Finally, u will come up with layers of the model.
   - Decide areal extent of the model.
   - Choose no flow boundary condition, if any of the layer is in contact with
basement(physical boundary of the model).
   - Choose constant head boundary on the other sides of the model boundaries if
the effect of the stresses will not change the head.
   - See where the recharge is possible (out crops) and choose those areas as
recharge boundary condition.

   With more information coming, you can update your conceptual model.

hi sri devi,

   It depends on your model, what type of maps you use.

   I usually use several .DXF or .shp files prepared from any GIS software, one
each for each property like recharge (outcrops maps), layers extents etc.

   basic aim of base maps is to guide you to the features on ground surface and
also if you are working on multi aquifer model, base maps (dxf etc) will help
you in knowing where your aquifers pinch out or there areal exent so that its
help ful for you in assinging hydraulic parameters.

   hope this helps you,

   hashmath

Andras,

Thanks for your speedy response to my need. As you suggested, I also
import a basemap (bitmap) and georeference it, then I rotate and resize
the model domain as I think appropraite. However, when the final model
region is created, the grid is still vertical, only my map changes
orientation (e.g. from being vertical to horizontal). Is this normal or
I am doing something wrong? Your help is greatly appreciated.

Dear Sir/Madam

I would like to prepare the input files of Modflow (PM51) externally (by another
application). The input files are *.con,*.htc,*.lea and so on.
It's done now, but a problem has occured. In short, Modflow doesn't look at my
input files - bas.dat, bcf.dat and etc. I found out that I should "regenerate
input files" before running modflow.
This may be done by ticking the relative checkbox in run dialog, while running
modflow manually.
1- Is there any way to enforce Modflow to regenerate input files automatically?
(a switch, a preferences or ...)
2- If not, what are the format of these files. (Fortunately they are text
files).

Sincerely,
Mortazavi

Courses: Model Calibration and Predictive Uncertainty using PEST
Shrewsbury, England, September 13-15, 2005
Stony Brook, Long Island, NY, September 19-21, 2005 (near MacArthur Airport
and Port Jefferson)

Principal Instructor: Dr. John Doherty (author of PEST)
Guest Instructor: Jim Rumbaugh (author of Groundwater Vistas) (New York
course only)
Assistant Instructor: Matt Tonkin

This intensive course instructs participants on the automated calibration of
environmental models, and the analysis of the predictive uncertainty
associated with such models.  The principal instructor is the developer of
PEST, the industry standard package for model-independent, automated
calibration and predictive uncertainty analysis.  The course focuses on the
use of PEST, including the new capabilities added to Versions 8 and 9 this
year. The course includes thorough coverage of the theory and application of
nonlinear parameter estimation techniques in the calibration of different
types of models. There is a strong practical aspect of the course -
participants gain hands-on experience in the use of PEST, including its
advanced regularization and predictive analysis 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.

Dear All,
Have you got any experience in modellig of water inflow in mine shaft ?
The problem is how to model the shaft?

The shaft is 400m deep, its perimeter is 4m. There are 3 vertical
dewatering boreholes located around. The value of total inflow into
the shaft is known, the inflow comes from several aquifers.
A vertical barrier of impervious material is planned arround the shaft
(from ground surface level to a depth of 70m) and the dewatering
borholes closed. The goal of the model is to find what will happen
with the water table and how much the inflow may decrease.

What should be the best aproach in modelling the shaft?

Adam

Dear Sir/Madam


I would like to control "Processing Modflow v.5.1.7"
from another program. For example, I need open a
project and run it externally. Is it possible? (Is
there any command line option for it? any switch?).

Thanks, in advance.
Sincerely yours,
M. Mortazavi

Dear Hashmath,

Since Visual MODFLOW and PMWIN are both pre and postprocessor for the
same simulation routines like MODFLOW, MT3D etc., there is not
principal difference between these two packages. My opinion that it is
better to download demo version of Visual MODFLOW and free version of
PMWIN 5.3 and start to do some models. After some time you will
understand which one has more comfortable interface for you, better
support for operations with you specific data, whether package
supports all routines that you need, and so on.

Best regards,
       Dan Kuznetsov

Hi,
Maybe this is a dumb question, I am new to Visual MODFLOW Pro 4.0. I
am evaluating different alternatives for a cleanup project. One
alternative for example is pump water out of the aquifer. Is there a
way to compute the remaining mass of a component (for example TCE)
at a particular time?
THanks for the info

In Version 4 of Vmod there is an export tool for every single layer surface.
You can find it in the input menu under file/export/data. Create a xyz
file - choose your coordinate system and then reimport in your transientr
data set
Good luck

Hello

I have the next problem:

I am working with a model, not created by me, and lately I have
received lots of information from new wells and I have dramatically
changed the elevation of bottom surface of the bottom layer in my
steady state file (calibration file), and consequently I would like
to have the same elevation in the transient flow files, but since
there is not an export grid tool, I do not know what to do.

I hope I have explained well the problem

Excuse my English

Thanks
