Mohamed,
A lot of general information and references related to ANNs are available
at URL: ftp://ftp.sas.com/pub/neural/FAQ.html
As you probably have seen in the hydrologic literature, ANNs seem to have
been more commonly applied to surface water or climatic phenomena.
However, below are some references where they have been applied to ground
water. There probably are more, but these are some I have happened to
come across:
Journal articles with ground water applications:

[hydrologymodel] Artificial Neural Networks (ANNs) and Genetic Algorithms
(GAs)
Dear Friends and Colleagues,
I hope you've all been keeping well. I am Ph.D student in Egypt. I am
working in groundwater Hydraulic. I need any references, papers, articles,
documents, ...etc in using evolutionary computational techniques such as
Artificial Neural Networks (ANNs) and Genetic Algorithms (GAs) with
groundwater modeling system (quality and quantity) to develop the
computational framework and the optimization approach. Also, any simple
reference about principles of ANNs and GAs.
Looking forward to hearing from all.
Thanks in advance

hi roshni,
take time seires of groundwater level ,take probably last 20 years data, the
well or any other site frm which the groundwater level has been measured , does
it gives the correct indication of waterlevel for that rigion, do u check it or
do u have any reference for it,if its correct then divide groundwater level time
seried into 3 subsets on the basis of marked fluctuation, then used first subset
for training second for calibration and third for forecasting.

1998-2001 for training and 2002-2003 for validation. Sir, I thought
that, If I have the data up to 2004, I can forecast for 2005 Jan,
Feb, etc. So for training the data from 1998-2001, for 1 year ahead

it the same groundwater values from 1998-2001 or from 1999-2002.

Final Declaration Holds Diluted View of Water as
a "Right"
Diego Cevallos
MEXICO CITY, Mar 22 (IPS) - The assertion that
access to water is a
human right was not included in the ministerial
declaration adopted at
the Fourth World Water Forum, which ended in
Mexico on Wednesday, World
Water Day.
Although all of the delegates said they agreed
with the principle, some
argued that it was not feasible to include it in
the final declaration,
because it could generate legal problems at the
national and
international level.
That stance was criticised by activists, who said
the refusal to include
the assertion was "a clear indication" that
transnational corporations
and rich countries do not want to budge an inch
in their aim to
"commodify" water, to which 1.1 billion people in
the world do not have
access.
Water is a "guarantee of life for all of the
world's people" was the
compromise formula agreed by the government
delegates taking part in the
Mar. 16-22 Forum.
The delegates of the 148 participating countries
agreed to sign the
(non-binding) document, in which the governments
pledged to work towards
the goal of universal access to sanitation and
safe water, after
negotiating the inclusion of an annex that
expresses a dissenting view
held by several governments.
In the appendix, Bolivia, Cuba and Venezuela
expressed a stance in line
with the positions set forth by the activists
taking part in a parallel
civil society forum, stating unequivocally that
access to water is a
fundamental human right.
The three Latin American countries, which are
governed by leftist
leaders, also expressed "deep concern" over the
possible negative
impacts that international instruments like free
trade and investment
agreements could have on water resources.
By contrast to the final declaration, the United
Nations Educational,
Scientific and Cultural Organisation (UNESCO)
also declared Wednesday in
Mexico that access to water is a fundamental
human right.
UNESCO Director-General Koichiro Matsuura said
nations that are
signatories to U.N. treaties have a "moral
obligation" to consider water
a human right.
According to the activists who took part in the
Mar. 17-19 International
Forum in Defence of Water, a civil society
gathering that produced an
alternative declaration, the dissent expressed at
the Forum showed that
the organisers were only interested in turning
water management into a
business opportunity.
"We didn't expect anything different or better to
emerge from the Water
Forum, we knew this would happen," Claudia
Campero, spokeswoman for the
Coalition of Mexican Organisations for the Right
to Water (COMDA) -
which organised the alternative events held
parallel to the World Water
Forum - told IPS.
The Forum itself was convened by the World Water
Council, an
international think tank founded in 1996 that
deals with water policy
and is made up of 300 representatives of
business, government
ministries, academic centres, multilateral
financial institutions, U.N.
agencies and local governments.
Because the founders of the Council included
executives from
multinational water companies like Suez in
France, activists argue that
the World Water Forums only represent and express
the interests of
transnational corporations and industrialised
countries..
According to the "Joint Declaration of Movements
in Defence of Water",
which was adopted by last week's civil society
meeting and signed by
around 300 non-governmental organisations (NGOs)
from 40 countries,
water is a "common good" and access to water is
an essential and
inalienable right.
The "Joint Declaration" states that water is not
merchandise, which is
why the NGOs reject all forms of privatisation,
even public-private
partnerships, which "have proven to be a complete
failure around the
world."
Argentine Environment Secretary Atilio Armando
Sabino argued that the
exclusion from the final declaration of the
assertion that the right to
water is a human right did not tarnish the
consensus achieved by the
governments that sent delegates to the World
Water Forum.
Underscoring that water is a "guarantee of life"
for humanity
demonstrated sincere concern over the issue on
the part of all
governments, he maintained.
It was "a bit difficult" to include the right to
water in the
ministerial declaration because it would have
committed many countries
to modifying their legislation and would have
forced international
bodies to create new legal instruments, explained
the official.
The document declares that water and sanitation
services must be
considered top priority in development policies,
and that continued
efforts and follow-up are necessary to meet the
goal of reducing the
proportion of people worldwide without access to
these crucial services.
The Millennium Development Goals (MDGs) agreed by
the U.N. member
countries in 2000 include a target of halving the
proportion of people
without safe drinking water, by 2015.
Eugenio Barrios, an activist with the global
environmental conservation
organisation WWF (formerly known as the World
Wildlife Fund), described
the Fourth World Water Forum as "disappointing."
"We were hoping for advances and for the
ministerial declaration to be
much more forceful, and to propose practical
measures in favour of
access to water. We are sorry that did not
happen," Barrios told IPS.
WWF took part in the Forum through several
conferences as well as
meetings with delegates.
The privatisation of water supplies, which
according to some activists
was the ultimate goal of the Forum, was not a
central issue in the
debates, and the stance that water is a public
good was also advocated,
said Barrios.
David Boys, with the France-based Public Services
International, a
global trade union federation made up of more
than 600 public sector
unions from 140 countries, agreed with that view.
"Even the World Bank
acknowledged here that the privatisation of water
has been a failure,
which was something new that was not heard at the
previous forums," he
told IPS.
But the final declaration was "very weak," said
Boys, whose organisation
has urged the World Water Council not to invite
government ministers in
the future, since the Forum is neither organised
by the United Nations
nor by governments.
"It is the United Nations that should organise
international conferences
on water, not a private body," said the trade
unionist.
More than 13,000 delegates of private companies,
governments and U.N.
agencies, as well as a limited number of
activists, took part in the
Forum, paying registration fees that ranged from
240 to 600 dollars.
Although the World Water Forum is not an official
intergovernmental
meeting, it is considered the main platform for
the global debate on
water resources. The Fifth World Water Forum will
be held in Istanbul in
2009.
The last day of the Fourth World Water Forum
coincided with World Water
Day, which is commemorated every year on Mar. 22.
In a statement released in New York, U.N.
Secretary-General Kofi Annan
declared that despite its importance, water
continues to be "wasted and
degraded all over the world." He also pointed out
that 6,000 people,
mainly children, die every day from water-related
causes. (END/2006)

evapoarting 0.001 cum of water. (So, that much energy in watts is required to
evaporate 1mm of water over a sq. m). Then, you can find what you want.
Try it.

Dear all,
I have estimated monthly PET using Mintz-Thornthwaite method. The output is in
W/sq.m (watts per sq.m). I want it to convert from W/sq.m to mm/month or
m/month. I went through a lot of literature but I am unable to find the
conversion factor for it. Can u tell me the conversion factor or how to convert
it.
With the following I guess you can find what you need:
Radiation : 1 cal cm-2 d-1 --> 0.041868 MJ m-2 d-1
1 MJ m-2 d-1 --> 23.884 cal cm-2 d-1
--> 0.408 mm d-1
1 mm d-1 --> 2.45 MJ m-2 d-1
--> 58.6 cal cm-2 d-1
1 Wm-2 --> 0.0864 MJ m-2 d-1
--> 2.064 cal cm-2 d-1

III International Symposium on Transboundary Waters Management
Overcoming Water Management Boundaries
Invitation Letter
Dear colleague,
We are organizing the III International Symposium on
Transboundary Waters Management, to be hosted at the University of
Castilla-La Mancha, in Spain, from May 30th to June 2nd, 2006, and
co-organizer by UNESCO and SAHRA.
The Symposium will be focus on the analysis of all Water Management
Boundaries, which impose conditions for water managing. Beside the
natural or physical boundaries, coming from the basin limits or the
differences resources sources (surface, subsurface, or coastal), there
are other human boundaries. These come from the fact that water
resources are coupled with the larger reality of a region, including its
environmental, social, legal, and economic characteristics. This implies
that at various levels of responsibility may appear boundaries, which
must be overcome for a successful water management strategy. These
include boundaries from the international scale, to the national,
regional, local, or even individual scale. The meeting is intended to
provide an integrated forum for TWM, considering both natural and human
boundaries.
This third Symposium will build on the review and analysis of
transboundary basins and aquifer management issues that occurred at the
previous symposiums in November 2002 in Monterrey (Mexico), and November
2004 in Tucson (USA). Topics ranging from quantity and water quality
management, impacts of climate fluctuations, building flexibility and
robustness into compacts, non-conventional water resources, and improved
sharing of data will be considered. Market-based allocation approaches,
ecological conservation, legislation framework, and the need for greater
hydrologic literacy among decision-makers also will be included, in view
of their relevance in the international and interstate water resources
arena.
Keynote speeches and panel discussions by recognized experts will
address a range of topics critical to improved transboundary waters
management. Additionally, we are working on organizing a course on
Isotopes in Hydrology and their potential application to TWM, on May
29th.
Abstracts reception is open up to March 1st. Travel Grants and special
registration rates are available. We would very much appreciate your
participation in the symposium. It promises to be a lively and
interesting event, attended by researchers, policy makers, academics,
and representatives of NGOs from all over the world.
You may obtain more information, at http://www.uclm.es/congresos/twm/.
Let me know any particular question.
We are looking forward to seeing you at this meeting.
Yours sincerely,

Dear Tejaswi
Imagery file contains the actual data. Opening of the file should be done this
way. You go to ERDAS data import option, select the type of satellite and
sensor . Superstructured format . Software will convert the data format to
format of the software. I think that would suffice.

Dear Sirs,
I am Suresh Babu, a research scholar of Anna University, Chennai, India, doing
research in "Rainfall-runoff modeling especially dealing with SCS CN model
modifications".
I am glad to convey that I am at the verge of final stage of my thesis work.
While I did my first draft report of my thesis work, I (and also my supervisor,
Dr. K. Venugopal) feels something better way of presenting the results in my
thesis outputs.
In this regard, I am very much in need of your kind guidelines and helps on the
following queries.
To brief my work, I have used the USDA-ARS watershed database to propose a
modified version of SCS CN model. After data filtering works like P/S >
0.456inches, etc., I got 82 watersheds data(eventwise data) for the final
analysis. Including existing SCS models, Mishra singh model, and my proposed
models, I have totally 8 models for comparitive analysis. I have used Se and
Bias statistics to compare them in calibration as well as validation. And also
"t-test of related samples" were used to arrive at a conclusion on "significant
difference on the statistics" between the models.
Before going for above statistical comparison among 8 models, My supervisor
adviced me to test each model's validity for the given dataset watershedwise
before comparing one model with the other. ie., Acceptable or not acceptable
'Se' values to be tested to findout the watersheds for which each model provides
acceptable results.
For example, he says that, "if R=0.6 for a watershed data by Model 1, it
explains only around 40% of variance. so the Model 1 may not provide acceptable
results in calibration for that watershed, and can be noted down before
comparitive analysis, to strengthen the outcome of the analysis work."
For this purpose, I have searched to get a acceptable range (values) of Se in
various literatures of "SCS model" as well as in "rainfall runoff models". But I
con't get such guidelines so far.
In this regard, I need your valuable guideline. I like to know the range of 'Se'
or 'BiAS', or 'R' or all the above, to arrive at a grouping of watersheds like,
watersheds that has 'Acceptable results' or 'unacceptable results' based on
above statistic values.
My supervisor told that research works in RR modeling beyond 1970's were tested
like the above, and they have suggested some guidelines on the range of
statistics like R, Se, etc., by which the RR(rainfall runoff) model can be
validated as acceptable one or not, for the data set. I will be appreciating if
you suggested any relavent literatures or even contact persons, for the above
purpose. In the mean while, I am also searching for the same.
Here I have attached the Se values in calibration of Model 1 (M1) of 82
watersheds in ascending order of Se. And also listed the statistical summary of
Se values of all 8 models in calibration. From this, I like to know which are
the watersheds having 'acceptable Se' and 'unacceptable Se values'. I need your
general guidelines on this.
Note: Sy-standard dev. of observed runoff; MQobs-mean of the observed runoff;
Se-standard error of estimate.

In addition to the above, I wish your guidance and suggestion to present my 8
models comparison in more efficient ways. For your kind information, some of the
above model pair comparison yield contradict results from an expected one. ie.,
for example, it is expected that M6(3 parameter) should perform better than M3(2
parameter) mostly. But Se values comparison of 82 watershed show only 63% of
watersheds showed the above results in calibration. But M6 is structurally
consistent in its form, when compared to M3 model.
I hope that you might be understood my queries. Sir, Kindly write to me if you
require some more detailed results of my study for the above purpose.
I am expecting your valuable responses. I will be very thankful to you all.
With sincere thanks,
Suresh Babu.
