Dear Friend,
Jodhpur, a major city of Western Rajasthan in India, has been experiencing the
problem of rising groundwater levels in many parts of the city for last 11
years, after commissioning of the Rajiv Gandhi Link Canal (RGLC) which brings
canal water to Jodhpur city and stores water in Kailana lake located west of
Jodhpur city. Basements of buildings are being flooded in many parts of the
city. There can be one or more of the following probable reasons for rising
groundwater levels in Jodhpur city.
(1) Seepage from Kailana lake due to presence of lineaments/joints in Rhyolite
rock.
(2) Presence of impervious sandstone basement at shallow depth below the porous
Rhyolite aquifer in the city area.
(3) Seepage from pipelines carrying lake water.
(4) Leakage of used household water from unlined drain system.
(5) Reduced groundwater extraction from existing borewells and handpumps after
commissioning of RLGC.
For the above case, what would be the appropriate methodology to find the actual
reasons for rising groundwater levels in Jodhpur city and appropriate short-term
and long-term management plans for maintaining the groundwater levels at a safe
level.

Kumar

Dear Friend,
While climate change affects surface water resources directly through changes in
the major long-term climate variables such as air temperature, precipitation,
and evapotranspiration, the relationship between the changing climate variables
and groundwater is more complicated and poorly understood. The greater
variability in rainfall could mean more frequent and prolonged periods of high
or low groundwater levels, and saline intrusion in coastal aquifers due to sea
level rise.
Groundwater resources are related to climate change through the direct
interaction with surface water resources, such as lakes and rivers, and
indirectly through the recharge process. The direct effect of climate change on
groundwater resources depends upon the change in the volume and distribution of
groundwater recharge. Therefore, quantifying the impact of climate change on
groundwater resources requires not only reliable forecasting of changes in the
major climatic variables, but also accurate estimation of groundwater recharge.
Quantification of the groundwater recharge will help in taking appropriate
adaptation strategies due to the impact of climate change.
There have been many studies relating the effect of climate changes on surface
water bodies. However, very little research exists on the potential effects of
climate change on groundwater. The scientific understanding of an aquifer's
response to climate change has been studied in several locations within the past
decade. These studies link atmospheric models to unsaturated soil models (such
as Visual HELP), which were further linked into a groundwater model (Modflow).
The groundwater models used were calibrated to current groundwater conditions
and stressed under different predicted climate change scenarios. The
HELP-MODFLOW approach proceeds in the following manner -
1. Synthetic generation of daily values of precipitation, mean temperature, and
solar radiation (using a weather generator) for projected climate change.
2. Estimation of groundwater recharge based on available precipitation and
temperature records and anticipated changes to these parameters (using Visual
HELP).
3. Quantification of the spatially distributed recharge rates using the climate
data and spatial soil survey data.
4. Simulation of groundwater flow using each recharge data set and evaluation of
the changes in groundwater flow and levels through time.
Regarding the above approach, I would like to know the views of learned members
on the following aspects -
(a) Which is the most appropriate method to downscale GCM outputs for a basin?
(a) If there are any flaws associated with HELP-MODFLOW methodology (described
above) mostly used by various researchers during last few years?
(b) If the runoff generation process (rainfall-runoff modelling) needs to be
essentially incorporated in the study?
(c) Whether instead of HELP, distributed unsaturated modelling (Richards
equation) should be done for climatic impact studies? What are the relative
advantages of using HELP (e.g. simplistic approach and ease of use) and
disadvantages of distributed modelling (e.g. extensive data requirement and
large computation resources) and vice versa?
(d) Whether any comprehensive overland-unsaturated-saturated model such as
MIKE-SHE can be used for studying the impact of climate change on groundwater
recharge? And relative advantages and disadvantages?
I look forward for the comments on above.

Kumar

Re: Modelling of seawater intrusion
Monday, September 22, 2008 3:52 PM
From: "alessandro.casasso" <alessandro.casasso@...>
To: "C. P. Kumar" <cpkumar@...>
Have you found any answer to you questions? I'm working at a MS thesis about
Feflow modelling of a shallow aquifer in Venice. I will not try to model salt
pans - too difficult even to think where they are.
About rainfall and evapotranspiration: I've got rainfall and temperature data. I
calculated ET with Blaney-Criddle formula, but I found that results are
overestimated. I tried to reduce risults by comparing modeling results with real
results (in the area I'm studying, I can get results from 11 piezometers..) and
I found that BC formula results can be divided by 3. I found that ET estimation
is one of the most difficult parts of shallow aquifers modeling...
I've got no idea about brackish water in rivers. In my model, I assigned the
tidal oscillations (1st type boundary conditions) also to a channel of Venice
lagoon that encloses my modeling domain.
I developed a relation between TDS and conductivity (I've got specifical
conductivity measures), but I did a very rude approximation. As I'm modeling a
peninsula, I thought that seawater contains most NaCl , so conductivity
(microSiemens per cm) is dominated by NaCl concentration. Conductivity is linked
to NaCl concentration in this way: - every ion has an equivalent conductivity,
that is the specifical conductivity for a concentration of 1 equivalent/liter
(for NaCl, 1 equivalent = 1 mole); - this equivalent conductivity is also linked
to concentration by Onsager formula; - specifical conductivity = equiv conduct x
concentration [mole/liter]
I visited your site some time ago, I found it very interesting. Sorry for my
English, I have to improve it. About my tip on TDS-conductivity: as we say in
Italy "here I tell it, and here I deny it" :-) I'm only a MS student and I got
these advice reading a laboratory chemistry manual...
See you soon on this forum,
Alessandro Casasso

Dear Group Member,
I am grateful to the following members/experts for their interesting/useful
observations/comments/suggestions on my report "Modelling of a Coastal Aquifer

(3) S.V.N.Rao (Roorkee, India)
(4) V.V.S. Gurunadha Rao (Hyderabad, India)
(5) Michael Jorgensen (Australia)
I am prompted to seek further suggestions for the following issues in modelling
the seawater intrusion in coastal aquifers.
(a) How to model the effect of salt pans on groundwater in coastal areas?
(b) How to incorporate the evaporation from open water surfaces (e.g. to define
time-variant boundary condition in case of rivers) and evaporation from shallow
groundwater table?
(c) How to model the effect of brackish water in rivers (due to tidal backwater
effect from sea) on groundwater in coastal areas?
(d) How to develop correlation between resistivity values and TDS and between
resistivity values and hydraulic conductivity.
(e) Suitability of Kriging, Akima and Inverse Distance Weighting techniques for
interpolation/regionalization of different parameters/variables.
Any suggestions for the above will be helpful for extension of this (or similar)
study in future.
There is a small errata in the report - title of figure 7 may be read as

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.

Unfortunately for conscientious water managers here in the USA the senior
management of our agencies has been 'persuaded' by exploitation of
self-interests to discourage comment regarding the recharge of aquifers, to
'keep it at a minimum. This according to lower-level staff responding to my
questions about what I consider negligence in researching/reporting planning
options. They recognize the importance of modifying land surfaces to maximize
infiltration but are frustrated by not being able to focus upon this
appropriately.
The same constraint frustrates new civil engineers entering service in major
cities. Their bosses simply do not want to see groundwater replenishment
investigated or recommended to landowners and concerned citizens. In fact some
were specifically forbidden to discuss this matter with reporters or the general
public.
This baffled me in the late '80s but as I became aware of the depth of private
influence upon civil engineers at every level in public and private employment
the reasons became clear. The primary reasons for blatantly inappropriate
rainwater management:
- Guiding roughly 1/5 of runoff from a major storm to infiltration sites would
allow existing stream/river channels to carry the remainder without flooding.
This would deprive civil engineering firms of their most profitable work load.
It would also nullify the most effective weapon of land speculators for
multiplying the value of cheaply purchased land many times over with public
funds. For this reason land speculators posing as developers commonly pay
lucrative fees to civil engineers for minimial work performed if they testify
falsely about the cost/benefits of onsite retention of rainwater. This
testimony fools politicians and concerned citizens into approving drainage-based
planning/design instead of storage-oriented comprehensive watershed management
plans.
- Keeping aquifers full with Best Management Practices would eliminate need for
the centralized water supply systems that are another major source of income for
the civil engineering profession and a huge body of private profiteers.
- Perennially full aquifers would allow individuals to depend upon wellwater,
greatly reducing the power of land speculators collaborating with public works
agency managers to manipulate land values through selective extension of
waterlines. This is a major weapon of unscrupulous land speculators and a
primary tool for public
works managers to maintain-expand their entrenched bureacracies.
In summaary:
There are many reasons to obstruct-distort-delay adoption of commonsense best
rainwater management practices that turn watersheds into sponges instead of
sheets of teflon. There are few reasons for unprincipled professionals to
accept the recommendations of every capable civil engineer and technician that
retention of rainwater where it falls be made the central focus of land
planning.
Consider that;
- Storing most rainwater underground achieves multiple public benefits at
minimal expense.
- Costs for homesite improvement are significantly reduced by eliminating storm
drains-wide streets-roof gutters-retention/detention ponds.
- Costs for water supply are lower and water quality higher with onsite
retention planning than with centralized drainage and water supply systems.
- Public expenses for energy is much lower with homesite wells because nature's
gravity- based water storage/distribution system is far more efficient - and
reliable - than the pipes and pumps that civil engineers rely upon.
- The cost of 'flood control' (note the oxymoronic character of this term)
decreases rapidly as homesites-woodlands-croplands-pastures are converted to
retain their rainwater onsite. Public works agencies can be progressively
downsized with great savings to taxpayers.
Despite the glaring flaw of not advocating "catching raindrops where they fall"
these websites are a useful tool for persons who let common sense guide their
conceptual planning, are not fooled by tunnel-visioned experts. Smart
modification of land surfaces using simple
grading-berming-terracing-revegetation methods will revive springs and seeps
throughout s watershed by maximizing the infiltration of rainwater. Greater
source flows mean fuller surface reservoirs.
Search "CSIRO groundwater model" but be aware that its principals are also
focused upon dealing with what is available rather than magnifying this supply
with simple, inexpensive, multiply beneficial "best management practices". They
speak of "artificial groundwater recharge" on specific sites instead of the
enhancement of natural infiltration throughout their catchments, revealing
deficiency in their broad view of rainwater management. But they do good work
otherwise.

Dear Group Member,
I am grateful to the following members/experts for
their interesting/useful
observations/comments/suggestions on my report
"Modelling of a Coastal Aquifer using FEFLOW"
(available at ftp://ftp.wasy.de/FEFLOW/Goa.pdf ).
(1) Reinhard Zapata (Waterloo Hydrogeologic, Canada)
(2) Krishnaiah C. (India)
(3) S.V.N.Rao (Roorkee, India)
(4) V.V.S. Gurunadha Rao (Hyderabad, India)
(5) Michael Jorgensen (Australia)
I am prompted to seek further suggestions for the
following issues in modelling the seawater intrusion
in coastal aquifers.
(a) How to model the effect of salt pans on
groundwater in coastal areas?
(b) How to incorporate the evaporation from open water
surfaces (e.g. to define time-variant boundary
condition in case of rivers) and evaporation from
shallow groundwater table?
(c) How to model the effect of brackish water in
rivers (due to tidal backwater effect from sea) on
groundwater in coastal areas?
(d) How to develop correlation between resistivity
values and TDS and between resistivity values and
hydraulic conductivity.
(e) Suitability of Kriging, Akima and Inverse Distance
Weighting techniques for interpolation/regionalization
of different parameters/variables.
Any suggestions for the above will be helpful for
extension of this (or similar) study in future.
There is a small errata in the report - title of
figure 7 may be read as "Measured Values of Hydraulic
Conductivity (*10E-4 m/s)" - the multiplier was
missing.

International Training and Research Program:
Groundwater Governance in Theory and Practice
Call for Groundwater Management Fellows
The International Water Management Institute led
Challenge Program on Water and Food project:
“Groundwater Governance in Asia: Capacity Building
through Action Research in the Indo-Gangetic (IGB) and
Yellow River Basins (YRB)” invites Fellows for the
training and research program on Groundwater
Governance and Management.
International Training and Research Program:
“Groundwater Governance in Asia: Theory and Practice”
Period (tentative): November 13, 2007 to March 30,
2008 (inclusive of classroom sessions, cross-cutting
research, field visits and concluding workshops)
Host: International Water Management Institute (IWMI),
New Delhi office; Indian Institute of Technology
(IIT), Roorkee (Uttaranchal) and other partners with
workshops in other basin countries
Basin Countries: Bangladesh, China, India, Nepal, and
Pakistan
Organizer: International Water Management Institute
(IWMI), Sri Lanka and its regional offices and partner
organizations in the basin countries
Background
Globally, groundwater has made tremendous contribution
to human welfare. The Indo-Gangetic basin and Yellow
River basins between themselves use around 300 km3 of
groundwater with value of groundwater used/year
estimated at $13.8 billion. Sustaining the massive
welfare gains groundwater development has created
without ruining the resource is a key water challenge
facing the millions of farmers and water resource
managers of these basin countries. The capacity and
skills of groundwater managers need to be
significantly enhanced to rise to the challenge of
governing the ‘colossal anarchy’ spawned by
groundwater use.
This training and research program sets out to address
the pertinent and very pressing issues of groundwater
management. The rationale is that groundwater is an
‘endangered species’ that is threatened from overuse
and degradation from many sides and that needs and
merits attention, appreciation and protection from all
of its users as well as the public suppliers and
management professionals and institutions.
The course targets people involved in groundwater use
and management at various levels and functions.
Individuals with positions within groundwater
development and management, groundwater research,
capacity building and awareness raising will be
invited in order to foster an inter-disciplinary
understanding, communication, debate and partnership
on the tackling of relevant and practical groundwater
issues in the regions covered by the project.
Who is eligible to participate?
Junior and senior professionals and managers involved
actively in groundwater management and research in the
five project countries (Bangladesh, China, India,
Nepal, and Pakistan, desirably working in basin
regions, Fig.1) are eligible to apply and participate
in the program. Preferably, the applicants should be
affiliated with an established and recognized
organization or institution in the region involved
actively and mandated with groundwater management and
research. Professionals working with Central/ State
Groundwater Boards and related water resources
departments, institutes, universities, INGOs/ NGOs/
donor agencies and all those interested in groundwater
management and governance are encouraged to apply.
People involved in media coverage (content development
and dissemination) on development and environmental
issues and associated with a well-established and
recognized media organization are also invited to
apply.
Course content and training program for Junior Fellows
The Course consists of two parts:
A four week intensive class room course; and
A 12-week training/ crosscutting research program
under live field conditions
The first part will cover theoretical as well as more
case/ region oriented aspects of groundwater, giving
both fundamental introductions to the physical
behavior and characteristics of groundwater, its use
for agricultural production, social sciences,
economics and institutions, policies and governance;
scientific methods in research and field visits.
Delivery of the course shall be through a
well-balanced illustrative and conjunctive treatment
of the various themes through case presentations,
simulation games, field trips and discussion sessions.
There shall be ample opportunities for cross-learning
the regional perspectives of groundwater among the
participants from different countries.
Cross-Cutting Research (CCR)- the practical fieldwork
based component of the course is a 12-week program
that involves three components- five weeks of field
work followed by five weeks of data entry and analysis
and two-weeks of report writing and presentation
workshops. Participants shall be encouraged to go back
to their individual country to do a small but well
planned study or investigation on a specific issue
that either provides them with better knowledge and
tools to pursue their function after the course or it
may be a research topic that fits into a larger
research component of the project that is led by IWMI.
During the first phase, the participants will select
very interesting topics related to resource
characterization and use, sharing mechanisms, formal
and informal water institutions, energy and pricing
mechanisms, groundwater pollution problems. During the
CCR phase the fellows will investigate, through
questionnaires, surveys and data collection, how
groundwater is actually being used and how it relates
to water availability, land use; agriculture, water
and energy policies and other socio-economic factors
in selected regions of the two basins. In the process,
the fellows would directly apply the knowledge gained
at the classroom-training program on the complex
realities of groundwater governance in Asia and
capture the same in the form of group reports/ case
studies and individual theme papers.
Training Program for Senior Managers and Professionals
(Senior Fellows)
The Program for the senior fellows will be of
four-weeks duration and comprise of the following two
components:
One-week exposure to the high level sessions on
management and policy implications of groundwater
governance and the global best practices.
Three-week action research/ study visits to advanced
countries (Australia and/or USA etc. ) in order to
retrieve as much knowledge and information on
groundwater management practices in the host country
to understand some fundamental practices/ processes,
conflicts and challenges faced in groundwater
governance and the specific ways, policies and tools
which have been developed and employed in these
developed countries. Fellows will get a fair
opportunity to interact with a cross section of active
stakeholders in groundwater governance and management
at different levels.
During and at the end of the visit the fellows will
develop individual reports on these learning and
contextualize these experiences for their own settings
in the respective countries. During the first phase of
the Course the senior Fellows visited South Australia
state in Australia and Kansas State in the USA.
Training Program for Media Fellows
Realizing that groundwater is an inadequately
understood, invisible and disregarded water resource
in many respects, general and scientific awareness
raising shall play a key role in future groundwater
management. In order to support this media fellows
with strong interest in development and environmental
reporting are invited to participate in the course.
The program shall follow that of the junior fellows
described above but additionally some specific events
of particular relevance to them shall be organized.
The research program for the media fellows will be
devoted to the development of a couple of news
coverage, development of documentaries and specialized
reports on relevant topics related to groundwater in
their region of interest.
Resource Persons for the Program
Resource persons for the course and training/
crosscutting research components will be drawn both
from the region and from world-renowned international
institutions. The regional experts shall provide
country specific local knowledge; relevance and
applicability of theory and practice under specific
settings and international experts shall strengthen
the program through incorporation of state-of-the-art
knowledge on technology, practices and global best
practices on groundwater governance. Experiences from
the interesting case studies from the first phase
shall also be optimally utilized.
Cost of Course Participation
The cost of the course and training/ crosscutting
research will be covered by the Project, including
traveling (local/ international), course materials,
food and accommodation etc. In addition, a modest
per-diem shall also be provided to cover for
additional incidental expenses. However, it is
expected that the fellows will continue to retain
their association/ liaison with their respective
employers, and hence shall receive their normal salary
and allowances during the duration of the course. The
entire duration of the course may be treated as
deputation/ attachment to the Program.
Course language
The entire course and training components shall be
conducted in English.
Course Certificate and Post-Course Benefits
All successful participants shall be awarded an
international course certificate/ diploma in
partnership with lead participating organizations.
Participants will also have the opportunity to
publish/ co-author their outputs of the action
research in the form of international reports/ journal
articles/ popular articles/ case studies/ media
reports and course sponsored synthesis publications.
Equally, or more importantly, the participants will be
part of a continuing international and inter-regional
community/ society or partnership on groundwater
governance and management that will ensure continued
collaboration and knowledge sharing across various
institutional and geographic boundaries.
How to Apply?
The course participants shall be selected through a
suitably designed process aimed to provide fair
representation to the basin region countries,
professional disciplines/areas of interest, gender,
experience and potential benefits. In order to be
eligible for joining the course and training program,
A completedl application (in the prescribed format)
has to be submitted to IWMI. (For application forms:
Junior and Media Fellows or Senior Fellows)
In addition, for junior and media fellows, a written
formal nomination/ recommendation from a superior of
the organization for the total duration of the course
is required.
A well-drafted concept note, describing a research
topic of interest and relevance to the applicant and
how to address it within the training program should
be developed and submitted along with the application
form.
Senior Managers/ Fellows should submit with their
application a note stating the motivation/ valid
reasons for joining the training program and expected
benefits. Suggestions on the name of a developed
country to potentially visit for the action research
phase may also be indicated.
Last Date for Applications: August 10, 2007

Dear Member,
I am pleased to inform that I have recently completed
the study "Modelling of a Coastal Aquifer using
FEFLOW". A brief introduction of the study is given
below.
Coastal tracts of Goa (India) are rapidly being
transformed into settlement areas. The poor water
supply facilities have encouraged people to have their
own source of water by digging or boring a well.
During the last decade, there have been large-scale
withdrawals of groundwater by builders, hotels and
other tourist establishments. Though the seawater
intrusion has not yet assumed serious magnitude, but
in the coming years it may turn to be a major problem
if corrective measures are not initiated at this
stage. It is necessary to understand how fresh and
salt water move under various realistic pumping and
recharge scenarios. Objectives of the study include
simulation of seawater intrusion in a part of the
coastal area in Bardez taluk of North Goa, evaluation
of the impact on seawater intrusion due to various
groundwater pumping scenarios and sensitivity analysis
to find the most sensitive parameters affecting the
simulation.
For the study, a finite-element model (FEFLOW) was
used for model simulations. The FEFLOW is an
interactive finite element simulation system (Version
5.1) for three-dimensional (3D) or two-dimensional
(2D), i.e. horizontal (aquifer-averaged), vertical or
axi-symmetric, transient or steady-state, fluid
density- coupled or linear, flow and mass, flow and
heat or completely coupled thermohaline transport
processes in subsurface water resources (groundwater
systems).
Salient conclusions of the study are given below.
(1) Presently, seawater intrusion in Bardez taluk of
North Goa is confined only upto 290 m from the coast
under normal rainfall conditions and present draft
pattern. It may slightly extend farther for low
rainfall years.
(2) Seawater intrusion may further advance inland if
withdrawals of groundwater by builders, hotels and
other tourist establishments continue to increase in
the coming years.
(3) Groundwater salinity needs to be continuously
monitored near the coastal area, especially within 2
km from the coast.
(4) Corrective measures with proper planning and
management of groundwater resources in the area need
to be initiated so that it may not turn to be a major
water quality problem in the coming times.
(5) The model is very sensitive to hydraulic
conductivity and dispersivity values. Field and
laboratory investigations need to be undertaken for
measurement of these parameters for use in further
modelling studies.
(6) The study will guide in making management
decisions to monitor and control seawater intrusion
and planning of groundwater development in the area.
I can send the complete report (in pdf format) by
e-mail to the interested persons. Your comments or
suggestions are welcome.

Kumar
