Greetings to you all,

Those who are looking for higher resolution DEM, I have a very good news to
convey!

Now, NASA/METI has released the 30m global (83°N and 83°S and is composed of
22,600 1°-by-1° tiles) ASTER GDEM based on 1,264,118 single ASTER dems from
1.4 million scenes in total. 95% vertical ci: 20 meters, 95% horizontal ci: 30
meters)

ASTER GDEM tilescan be downloaded electronically from ERSDAC by visiting the
link below: This web-based search system has 4 methods for tile selection. You
can select tiles with one of the following methods...

• Select tiles directly
• Select tiles by polygon
• Select tiles by shapefile
• Select tiles by coordinates

With FEFLOW, I experienced stability problems with models with
- an irregular mesh --> try the Smooth mesh tool;
- too high conductivity differences (elements with 10-8 m/s conductivity
adiacent to ones with 10-3 m/s) --> do what you can to "smooth" the conductivity
distribution.

May the 200 days of maximum time steps be tied to the power functions governing
the transient conditions? Considering you are simulating 10000 years... Good
luck!

Gio's advice is good. The problem may lie with conflicting boundary
conditions or bc constraints, which may or may not show up in the steady
state. Another possibility is the mode used, phreatic, confined, etc.
"Free and Movable" slices can be unstable. More information is needed to
make useful comments on the actual problem.

Hi,

There are problems of stability.
You should check the model before running it.

I suggest a couple of checks:

 at first run the model in steady state and check if it converges and that the
balance (IN-OUT) is fine for your problem, otherwise you have to control your
input, the number of layers vs deep, mesh etc
then I would rehash the steady state solution and I would run the new model in
transient conditionif that does not work, I would check again the mesh near well
points and verify how the model works without wells.Hoping this will help you!

Hello everyone...

I am doing groundwater flow and contaminant transport modeling for saturated
region with transient conditions. I am doing it for 1.0xE4 years. while doing
that i am facing two problems

1.Head values at some of the observation wells are oscillating 10-15 metres

2.Time step is not going beyond 200 days so it is taking so much time for
running. I am using automatic predictor corrector method.

i would like you all to give your suggestions so that i can resolve thee
problems.

Hi Pete,

Thank you for your answer. Actually I should have done a mistake and
some confusion.

You are absolutely right. A seepage boundary condition is constrained
and the constrains work as I want. Initially I assigned an atmospheric
pressure (constrained) along the angled hole. Using the automatic tool
for the definition of a seepage boundary, I basically assigned a total
head equal to the elevation of each node of the hole. But the hole is
angled, then I automatically assigned a different total head (equal to
the elevation of each single node) along the angled hole. This
situation was making me crazy because I was obtaining nonsense
results. Then I realized that I had to use a constant head value along
the drainage hole (the highest elevation of the hole) and it made more
sense at the end.

I am doing groundwater flow and contaminant transport modeling for saturated

Hi Giovanni,

I think FEFLOW 5.3 shuts off discrete features in the UZ, but you should
check with WASY about later versions.

It should work if you constrain the discharge node to stop any outflow
if the head at the node is lower than the elevation of the exit point of
the borehole. I think a head-constrained cauchy node should work.

Dear all,

I am dealing with a 2D transient and unsaturated model for
depressurization purposes. The client asked me to evaluate the effect
of horizontal drainage holes that I simulated as a seepage boundary.
In the same time I have been asked to do the same thing with inclined
((below the horizontal line) drainage holes. I was wondering if in
this case the seepage boundary condition can be applied or not.
According to me, such holes should work as the horizontal ones as long
as the elevation of the water table is above the elevation of the
highest point of the hole, but when the hole becomes partially
unsaturated water can come out from the hole because the gradient is
not great enough. Using the seepage boundary condition then,
overestimates the volume coming out from the model.

I was thinking to simulate it as an high conductive feature using the
"discrete element feature" tool, simulatin this condition as a very
permeable fault. Can the discrete element feature be used in an
unsaturated model ? As my holes progress with time can I generate a
power function for the property of a discrete element like a fault?

thank you
Giovanni

Dear Colleagues

A PhD student who is looking into geothermal possibilities at a location and who
has collected a lot of data has contacted us.

He needs to analyse the data with a groundwater modelling package called FEFLOW.
However, this is too expensive for him to buy based on his likely useage.

Could you suggest a means whereby he could undertake his analysis without
purchase of a licence as after the analysis it appears unlikely he will require
it for much ongoing work.

Many Thanks, All advice appreciated

Hi Mr. Giovanni

My model is saturated transient flow and contaminant transport with one river
with transfer boundary conditions. Others boundary conditions are constant only.
Most of the observation points are far away from the river.

Hi Manish,

Oscillations are common especially in complex models; whether they are
important depends on the whether the oscillations decrease to values
small enough to be of no concern and also if the mass balance of the
model is acceptable (eg small compared to total inflows and outflows).

it is hard to understand if it is problem or not. Can you provide more
details of your model? transient or steady? and in the first case are the
BCs transient ? Saturated or unsaturated model? are you using the re-wetting
capabilities (sometimes it could give some oscillations problems).

Oscillations can also depend on other stresses of the model. maybe your
observation point is close to a river that was defined with transient
conditions... there are several reasons for oscillations. Try to be more
specific.

Hi

I am facing a problem in feflow. It is when i am running my problem, the graph
of head values at various observation points is showing too many oscillations in
head values. Is anything wrong with that or it is just ok?

Greetings to you all,

Download SRTM 90m Digital Elevation Data (Version 4.2) The SRTM Data now
available from CSI-CGIAR SRTM Data portal. This is Free, and all the data has
been upgraded to version 4. This latest version represents a significant
improvement from previous versions, using new interpolation algorithms and
better auxiliary DEMs.

For quick & easy data downloads, this portal has a nice user-friendly web
interface which provides users three flexible options to choose, in order to
selecting multiple tiles for downloading.

1. Multiple tile selection by clicking on tiles
2. Drag the mouse-point on top of the world map and mark & select the tiles
3. or, enter lat-long input coordinates.

In addition, you can switch between their different SEVERAL hosting servers, to
select either HTTP or FTP downloads.

Greetings to you all,

This is an evolving drought monitoring tool, which, in its present form is based
entirely on remote sensing data. It aims to supply timely information on drought
onset, progression and areal extent. This near-real-time drought monitoring and
reporting system currently covers Afghanistan, Pakistan and western parts of
India. The system is based on drought-related indices derived from high
resolution remote-sensing data (MODIS).…

hi

	 Our team are working at a project on seawater intrusion in China, and
its the time to choose a proper software. Feflow, as our first choise,
is definitely the  most powerful and reliable one but I still have
some wonders may be you can help me with.

	 Our project this time including a information system (manage the sea
water data, developed through the ARCgis engine) and we want to add
several simulation models in to this system, I mean after we establish
the simulation models, we want to use feflow to do the calculations in
our integrated user interface rather than in feflow itself, and of
course the results have to be given in our system. As I know there is
no SDK in 5.3 or eailer.
