Greetings!

You and your colleagues are cordially invited to attend an exciting
three-day continuing education workshop on aquifer testing methods and
data analysis techniques featuring AQTESOLV at the University of San
Diego in San Diego, California, USA on February 27 through March 1, 2007.

For this course, we are privileged to have Dr. Shlomo P. Neuman from
the University of Arizona join us as a special guest lecturer. He will
discuss his important contributions to the pumping test literature
including the Neuman-Witherspoon (1972) ratio method and the Neuman
(1972; 1974; 1975) method for unconfined aquifers with delayed gravity
response.

Dr. Jim Butler, the 2007 NGWA Darcy Lecturer, will be with us again to
present cutting-edge concepts for designing, conducting and analyzing
slug tests. In addition, Glenn M. Duffield, the developer of AQTESOLV,
will lead hands-on classroom sessions in the computerized analysis of
field data with the AQTESOLV software.

We offer the only courses that feature hands-on computerized data
analysis with AQTESOLV, the world's leading software for the analysis
of aquifer tests (http://www.aqtesolv.com/).

COURSE SYNOPSIS:
Conducting pumping tests and slug tests in complex hydrogeologic
settings such as heterogeneous or fractured media is a key element to
site characterization, water resources assessment and remediation
system design; however, poorly planned aquifer testing programs often
lead to suspect data or unanswered questions after the field work is
complete. Even when you are confident of the geologic conditions, you
may have difficulty designing effective tests, running field equipment
or selecting the best available model to analyze the test data. When
can you turn to improve your approach and skills for aquifer testing?

Midwest GeoSciences Group can help! We have designed a powerful
three-day course on aquifer testing design, field methods and data
analysis techniques featuring AQTESOLV. This course will provide you
with the knowledge to master pumping tests and slug tests from
beginning to end. Gain an advantage by learning up-to-date methods and
procedures for designing, conducting and analyzing aquifer tests.

Pricing of ground water mooted - Symposium calls for a
new water policy

Gargi Parsai

NEW DELHI: A national symposium here on "Ground water
governance: ownership of ground water and its pricing"
has called for a new national water policy that should
spell out the demarcation needs between the ownership
and the right to use the ground water resource by
enacting integrated water laws. The thrust of the
recommendations and indeed the symposium, organised by
the Central Ground Water Board and the National
Institute of Hydrology, Roorkee, was to move towards
pricing of ground water, which was likely to mainly
affect farmers.

Calling for a paradigm shift in the role of the
government from provider and financer to facilitator,
the symposium recommended that the ownership of ground
water needed to be vested with the State governments
by making "suitable amendments" to the Constitution to
give effect to the National Water Policy-2002. It has
suggested a "slab system for water pricing structure".
Under this, the economically weaker sections and small
farmers could be charged for water at a subsidised
rate whereas for big (farmers)/users with increasing
demands, the water price could be increased
substantially.

"The governance and ownership and property rights
issues in ground water sector have not been properly
resolved and this is causing anomalies in water
management," said the participants including water
experts, engineers, and bureaucrats.

However, they pointed out that it was difficult to
prescribe "pricing" as one of the tools for better
ground water management, because it was difficult to
price or regulate a resource as the ownership rights
were not clearly defined.

Dear colleagues,

Can anyone explain the exact defenition of sorptivity, escpecially
with regard to dry soils.

In dry soils, when water is applied,
a) the soil drinks the wate very quickly
b)the water intake rate become gradual
c)reaches the steady state.

When we plot the graph of cumulative infiltration against the time,
in very dry soil, the slope for the process 'a' will be the highest.
and this slope is called sorptivity. (mm/hr^0.5). But the soprtivity
value must be less than the steady state infiltration rate - which is
obtained from the slope of the process 'c'. (mm/hr). -------- So,
some where there is mistake.

Can the sorptivity value be higher than the steady state infiltration
value ? then what will be the _expression for saturated hydraulic
conductivity ?

Or in very dry soil, can we take process 'b' as the sorptivity
factor ?

Hope someone will clear the confusion.

Thanks in advance

International Training and Research Program 2006-2007

Groundwater Governance in Theory and Practice

Under the CGIAR Challenge Program on Water and Food
Project:

Groundwater Governance in Asia: Capacity Building
through Action Research in the Indo-Gangetic Basin
(IGB) and the Yellow River Basin (YRB)

Background

Groundwater is a major source of water used in
agriculture as well as for domestic and industrial
water supply in most countries around the world. This
is no exception in South Asia and China where
groundwater has been a vehicle for much of rural and
industrial development over the last half century.
Groundwater is there, groundwater is developed and
used, groundwater generates jobs and income to many
citizens, yet groundwater is not really valued,
monitored, known, and much less managed or governed.

This training and research program sets out to address
the pertinent and very pressing issues of groundwater.
The rationale is that groundwater is an endangered
‘water species’ that is threatened from overuse and
degradation from many sides and that needs and merits
increased attention, appreciation and protection from
individual users as well as private enterprises and
management institutions.

The course targets people involved in groundwater use
at various levels and functions. Groundwater
development and management professionals, groundwater
researchers, and journalists are invited to
participate in the program in order to foster an
interdisciplinary understanding, communication, debate
and partnership on addressing the relevant and
practical groundwater issues in the region.

Program Objective

The overall objective of the training and research
program is to enhance the capacity of existing
institutions involved in groundwater research and
management in the basin states sharing the
Indus-Ganges and the Yellow River Basins (i.e., India,
China, Pakistan, Bangladesh and Nepal) to undertake
more integrated, multidisciplinary and sustainable
approaches to groundwater governance. The program will
train groundwater practitioners in applied research,
and will support lasting, interregional networks of
practitioners and researchers. The program intends to
seed a process of enduring change in the groundwater
management sectors of the states.

Participation

The program targets three types of fellows; 1) junior
and 2) senior groundwater managers and 3) media
fellows from the five countries. The program offers
joint learning forums among the junior and senior
management fellows; as well as separate components
tailored towards particular levels of experience.
Media fellows covering natural resources issues are
included during the training, to improve their
technical knowledge of groundwater as well as their
understanding of key regional issues.

Program Structure

The program is divided into two major phases as
follows:

Phase 1 is a classroom course on theoretical as well
as practical aspects of groundwater governance. This
5-week phase takes place at IIT (Indian Institute of
Technology), Roorkee, India, and other recognized
training institutions in the area, from Oct. 9, 2006.
Phase 2 is an action research program where the
participants acquire skills in groundwater assessment
and management through field surveys and
experimentation (junior and media fellows) and visits
to renown international institutions involved in
groundwater management (senior fellows). This 4 -15
week phase takes place in the five basin states
(junior and media fellows) or overseas (senior
fellows).

The second phase culminates in an annual project
meeting in March, 2007, where all three types of
fellows present findings and results from their
research phase.
Both phases of the program are mandatory in order to
complete the program successfully.

Content, junior fellows

The first phase will cover theoretical as well as more
practical and case-oriented aspects of groundwater. It
will give both a fundamental introduction to the
physical behavior and characteristics of groundwater,
the socioeconomic and institutional and policy
implications as well as the illustrative and
integrative treatment of the various themes through
case presentations, field trips, simulation games and
discussions. The course will combine lecture formats
with interactive discussion seminars.

The second phase consists of a 15 week action research
program, where junior fellows work individually or in
smaller groups on specific topics of relevance and
interest to their professional work. The participants
will go back to their individual country, or another,
to participate in a research program designed by the
project scientists. Typically, the fellows will
investigate, through questionnaires, surveys and data
collection, how users of groundwater behave and how
their behavior relates to water availability, land
use, policies and other socioeconomic factors in
selected regions within the two project basins
(Indus-Ganges and the Yellow River).

Content, senior fellows

In order to cater to senior managers, a shorter and
management-focused program that encompasses one week
of class room training and four weeks of action
research is scheduled. The one- week classroom
training will be concurrent with the last week of the
Phase 1 training program for junior fellows, focusing
mainly on management and policy implications of
groundwater governance. The second phase for senior
fellows is a 4-week research program that showcases
groundwater management frameworks in countries outside
of the region (e.g. the United States, Spain, and
Australia). The senior fellows will collect in-depth
knowledge and information on many facets of
groundwater management including fundamental
processes, conflicts and challenges faced and the
specific ways in which they have been addressed in
that particular country and the potential for transfer
of approaches to the basin states.

Content, media fellows

Realizing that groundwater is a ‘forgotten’ and
disregarded water resource in many respects, general
awareness raising is a must in future groundwater
management. In order to support this, journalists from
print, television, and radio with interests in
environmental and natural resource issues are invited
to participate. Their program follows that of the
junior fellows described above, but with some side
events of particular relevance to them. Their research
program will be devoted to the development of news
coverage or reports on relevant topics related to
groundwater in the areas covered by the junior
fellows.

Timing

The program starts on October 9, 2006 and ends in
March 2007

Five-week class for junior and media fellows, in India
One-week class for senior fellows, in India
Preparation of junior and media fellow action
research, in India Junior and media fellow action
research, in their country Senior fellow action
research, in country outside the basins First annual
project meeting, in India Sunday Indian national
holiday

Who is eligible?

Junior and senior managers and professionals involved
actively in groundwater management and research in the
five project states are eligible to apply and
participate in the program. Preferably, the applicants
should be affiliated with a well-established and
recognized organization or institution in the
region/basins that is involved actively and mandated
with groundwater management and research. Journalists
associated with a well-established and recognized
media organization are also invited to apply.

Media Fellow (MF): A young journalist working on
environmental and natural resources issues.

Target Countries

The program is open to participants with previous
experience in their professional career from the five
basin countries, i.e. India, China, Pakistan,
Bangladesh and Nepal, and who (preferably) reside in
the said countries.

Language Requirements

The program is conducted in English, and fluency in
speaking, comprehending and writing English is a
prerequisite. Candidates whose English is not their
mother tongue must certify their proficiency in
English.

Course Instructors

Instructors for the training and research program will

Sir,

I am doing my M.Tech at IIT Kharagpur. M.Tech project is forecasting
watertable fluctuation using ANN.


  I am taking monthly rainfall, previous month water table depth,
monthly river stage and monthly average temperature as inputs. I
tried with trainbr algorithm. I am not changing the parameters, only
I am changing the number of epochs, since they are taking the
default as 100.  I am scaling the data in to 0-1 domain. Can I use
the same algorithm for 1-, 2-, 3- ....month ahead up to 1 year ahead
forecasting. According to Daliakopoulos et al., (2005), feedforward
NN with LM algorithm provides best results up to 18months forecast
for an area in which groundwater has been steadily decreasing due to
over exploitation. Same situation is in my study area (Konan aquifer
in Japan) also. I have seven years of data (1998-2004). I considered
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
forecasting, what i have to give the target values for training?  Is
it the same groundwater values from 1998-2001 or from 1999-2002.

Expecting a reply
Thanking you

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

Dear Colleagues,

For use of high pH water for irrigation and other purposes a very simple
technique known as " Gypsum Chamber Technique" has been developed. In this
technique, high pH water from a tubewell is led into the inlet of a suitably
designed chamber holding gypsum clods. The raw water passes through the
chamber and moves up and finally is discharged through the outlet. Depending
upon the pH thickness of gypsum bed and passage time is designed. This
reaction substantially reduces the pH and makes the water usable. Further
details on Chamber design, size of clods etc. are available.

For tubewell facing frequent encrustation, two things need to be done. First
always use high quality PVC pipes instead of GI pipes which are more prone
to encrustation. Secondly, occasional flushing with sulfamic acid removes
all the encrustation and keeps the well/ pipes in good working condition for
a longer time.

Best regards.

Dear Dr.Susana

   Greetings

   Thank you very much for your information and suggestions. As the water
scarcity is a major problem in Oman, we are planning and searching suitable
method for the treatment of enormously available high pH water. The usage is
not restricted to domestic or agricultural or industries.

   Further, high pH water accelerates encrustation and deposition on well's
screens and casing as well as on pipes. This encrustation impairs well
design within very short time, and reduces the lifetime of wells and
pipelines.  Hence, we are expecting both treatment as well as remediation
(field scale) to solve this problem.

   Once again thank you very much for your information.

   Dear Dr Rajmohan,

The appropriate water treatment for your problem will also depend on
the water's end use.
For small domestic water supply, naturally you would be looking for a
cheap and simple water treatment method and for large water supply you
may have to go for industrial treatment which requires a water treatment
plant.  To give you an idea, the different treatment methods are
explained on this web link
http://www.ext.nodak.edu/extpubs/h2oqual/watsys/ae1045w.htm

Most water softeners substitute Na for Ca.  In your case this will not
work because you already have high Na over Ca.  Your sample is also very
saline which indicates you may have to go for reverse osmosis.  If the
end use for this water is drinking, you will need consult the drinking
water standards in your country to find out what levels you need the
water treatment to decrease those high ion levels.  You could be looking
at a combination of water treatment method.

I have seen many areas where the water level cuts the topography and huge amount
of seepage occurs

   In certain areas there are temporary flowing wells
   Such wells are seen even in hyderabad

   I am trying to search for a video recording that i have made two years ago and
i will try to upload that as an attachment for all of us to see.

subsurface there is composed of fractured limestone (The White Limestone
Formation), with an average effective porosity not more than 3%. It is easy
to calculate that the rainfall of 1 m with such a porosity could locally
produce the rise of levels between 30 and 40 m. The recession was much
slower due to low transmissivity of the limestone. Land (ground surface) is
of course composed of very permeable limestone formations with not too much
surface runoff.

Dear Vijayakumar,

   Good. The area of godavari valley is occupied by fresh-water fluviatile
sediments ofthe lower gondwana sequence sequence of rocks.

   Coming to the point of study reasons to be find out from:

   You check the following:
   1. slope of the terrain from canal towards to the observation well
   2. regional slope of the terrain
   3. dip and thickness of the sandstone bed and fracture/joint pattern in the
area of study
   4. sequence of the formations present and especially next below the sst
5. at what level the present well present
   6. observe the weathering depth of the formation in the area

   finally:  7.observe the records of rainfall and water level fluctuation in the
area before and after the canal excavation and during the canal flow times and
nonflow times

   8. observe the relationship of between the rainfall and water level
fluctuations

   with this analysis you could get the answers.

   Best of luck

   yours

Dear Vijayakumar,

   Good, Geologically that area is underlined by fresh-water fluviatile sediments
of lower gondwana sequence group of rocks. Tirupati sandstone itself is a good
aquifer.

   1. the groundwater level rose by about 18 metres from September to Novemeber
(post monsoon seson) in two increments seperated by a week. This has not been
experienced since 2002.
   2. The ground level is about + 45 m and The water level rose from -13 m to + 5
m above mean sea level.

   2. The previous year's high was about 8 m below the present high. Both highs
occur with in a week after end of rainfall event.
   3.Previously, when ever a gap of one week in rainfall is there, there was
recession in levels, where as now the recession limb is not falling like that
and daily pumping fluctuations in water levels were not so visible as they were
earlier. This seasons rainfall is about 50% more than that of last year, which
recorded normal rainfall.



   Fom the given information, i wish to inform you that you see the local dip of
the formation, joint pattern in the excavated canal and slope of the terrain
towards the well location from the canal.  You observe the rainfall vs water
level records of before the excavation of canal, see the withdrawl rate in the
local area and analyse the issue acccordingly.

     For all of your above queries, If the water flown in the canal, that might
have given recharge in the area during 2002, but might not have been in previous
year. you observe the record of water levels and rainfall and water flown in
cananl.


   best of luck

   yours

Another example, from Jamaica. Rainfall in June 2003 was in excess of 1000

This years rainfall in Bangalore has created the raise in the vadose ground
water level. Earlier the GWT was around 10 to 20 meters BGL when there were open
wells. Now a days the GWT has gone done to more than 30 to 40 meters in
Bangalore. Last month one of my friends garage was flooded due to the raise in
GWT of his bore well and several cases has been reported. However it was a
temporary phenomenon.

Dear Vijayakumar,

   May I know the local geological, topographical, Geomorphological,  structural
conditiions of the terrain ?

   I wish to know the exact location of the observation.

   And also, we should know the recent excavation distance from the existing ob
well, depth of excavation and topographical condition.

   We should see the rainfall history of the area.

   with wishes,

   yours
