Hey

I know this doesn't have to do directly with modeling but I was
wondering if anyone else was having a problem with arcgis 9.2 when
creating rasters from a group of points. The problem is that the raster
is created properly but it is not projected properly. It seems to just
floating in space with no real coordinates behind it.

I know that some other people have had this problem but I can't seem to
find a solution for it. If any one else has had this problem and knows
a solution it would be greatly appreciated.

Thanks Shaun

Hi Shaun,

   If I understood your question correctly -
   While converting to raster you can define a projection system OR you can
define the projection after it is converted.

   You can get more help on ESRI User Forums, which I found very helpful and got
immediate response for all my GIS questions.

   Good Luck,
   Swamy.

hey

Thanks for the help but the problem is not creating the raster or
putting a projection behind it, it is viewing the raster in arcmap.
it seems to loose its projection even though it has one. it is a bug
that happens in 9.2 and there is a fix for it as there is another
computer in the office that has been fixed but the lady who fixed it
has now left and no one else remembers how she did it. I have
searched the esri forums for helps and tried a few fixes they suggest
but they don't seem to work. I was wondering if anyone else has come
across this bug and if they knew how to fix it

thanks shaun

Hi,

   Once you have raster file created you can go to the Data Management Tool -
Projection and Transformations - Define Projection (under raster) and then you
can specify the raster file as input, select the projection you want and gives
the outputfile name.....

   Let me know if you have some other question.

Dear all,

I am modeling a karst area; I have some faults in this area. I have some
monitoring wells around the faults. These monitoring wells supplied us with the
water level changes in the wet season and dry season for two years. Also we
considered it as observation wells in a pump test. I want to take the faults as
the boundary for the study area, so kindly I need answer for the following:

Is it possible to know the hydrologic condition for the fault, and calculate the
flux across it from these monitoring wells?

Can you supply me with names or website for any papers or reports, solving this
problem?

Thanks to all members

Hi Nagaraj,

Probably a good place to start is the review paper written a while ago in
Hydrogeology Journal. Here is the reference.

Nagaraj,

The soil balance method that I'm most familiar with
right now is described in:

Dripps W.R. and K.R. Bradbury. 2007. A simple daily
soil-water balance model for estimating the spatial
and temporal distribution of groundwater recharge in
temperate humid areas. Hydrogeology Journal 15,
433-444.

This method was designed to use readily available U.S.
data from the Geological Survey, Natural Resource
Conservation Service, and National Weather Service.
The method has produced good results at a regional
scale for midwest U.S. areas. Depending on your needs,
it could be adapted to other data. My group is using
this method to estimate recharge for a regional
groundwater flow model.

Good luck,

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.

Hai,
I am working on numerical modeling in single rock fracture
Is anyone working in this line.
I am just looking for some literatures where turbulence has been
incrporated in rock fractures.(Specially wanting to know the initial
and boundary conditions)

To all PMWIN users,
I am using PMWIN software for my GW modeling.I am facing a problem in
reading the head data after performing the steady state flow
simulation.When I clicked Read option, it is displaying "The head file
c:\......\head.dat is saved in an unsupported binary format.
When I clicked O.K , it is showing head values as 0's only .What's the
problem ?

To all PMwin users:

The pmwin verion 5 that I am using supports modflow  modflow_96. Does
any body know where can I get PMwin which supports modflow2000 or 2005.

thanks all

Dear PMWIN users,

I am using PMWIN for my project on ground water modeling.I am having a problem
with file format.I ran th model for steady state
flow and when I tried to read the head file it is telling " the head
file c;\program files\pmwin\new-project\heads.dat is saved in an
unsupported binary format" when I said O.K it is showing all 0's as
head values. I am unable to fix this problem.Please tell me what I
should do to overcome this problem.

Jayaram.N.S.

Dear Jayaram,

   Check the head cell wise. It might be possible that you did some mistake
during interpolation of heads or inserting the head values. If the cell wise
values are not proper then it means you did the above mistake.

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 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@... :

  <http://www.sspa.com/Software/analytic.shtml>

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

I have been working on a groundwater model which models a contaminant
plume in a sand and gravel aquifer and have noticed negative
concentrations within the model. I have been using MT3D within
Groundwater Vistas and have been using TVD as the numerical solution
for solute transport.
The model has a consistent grid (5m x 5m)over the whole model domain,
with 10 horizontal layers each 2m thick. The geology within the model
comprises mainly boulder clay with a sand channel cut into the boulder
clay. The negative concentrations tend to occur within the boulder
clay adjacent to the boundary with the sand channel on the up-gradient
side, but are also present in some of the lower layers in the centre
of the sand body.

Does anyone know how to solve this issue / offer any guidance?

Kind regards

Hayley

Haley -

Take time to read this page.

I found it quickly after Googling "Grid Peclet number."

This tells you all you need to know about your problem.

Hi Hayley,

You have a lot of numerical dispersion occurring in your simulation.
This can occur if your time step is too large, dispersivity is less than
or equal to model cell size, imbalances in the flow due to poorly
converged flow simulation, etc.  Depending on the model, flow
discrepancy should be less than about 0.01%.  Abrupt changes in material
properties or stresses will cause flow imbalance, so look for ways to
limit such changes. Force MT3D to use smaller time steps by reducing the
curant number.  Try using a different transport solver.

Hello!
Please help me.
1. I dont understand where I choose units ( I see examples, but in
different examples  there are different dimension).
2. Recommend me issues about initial hydraulic heads in different
stress periods - rules and practise.
Thanks!
