Bridging Communication Gap…….Dissipating Information
A Biannual Newsletter
During the last 6-7 months, there has been a slight lull due to the hard-pressing engagements of the key functionaries of ISEG in their respective professional arena and transfer of some vital office-bearers outside Delhi. Despite the above constraints, there has been a good progress in the finance and
accounts and publications issues and ISEG‘s involvement in developing the ―Engineering Geology‖ theme of the ensuing 36th International Geological Congress – the mega global event to be held in India during 2-8 March 2020.
During the last two years their has been a colossal increase in the ISEG Life Mem-bership. It is heartening to note that young professionals and students has shown their keenness for joining ISEG.
Dear Members,
During my association with ISEG since last two years, I had received overwhelming love and affection of all members especially ISEG Council Members. Since its inception in 1965, ISEG has successfully evolved into a
vibrant community of efficacious professionals drawn from premier organisations who are contributing for the growth and development of Engineering Geology in the country. Being the India National Group of International Association of Engineering Geology and Environment (IAEG), ISEG has an additional responsibility of spearheading the promotion and encouragement of advancement of Engineering Geology through technical activities and its publications.
IGC is the Olympic of the Geoscientists organised once in every four years globally. India is the only Nation in Asia, which has the distinction of organising IGC for the second time. During 22nd session of IGC in 1964 in Delhi, the seeds of the birth of both IAEG (established in 1964) and its India National Group – ISEG (established in 1965) were sown. 36th IGC would be the rarest occasion for both IAEG and ISEG to celebrate their initiation of existence. I am happy to announce that we could successfully bring our international counterpart (IAEG) on-board for an interactive business meeting at the above global platform at Delhi during March 2020. Dr. Rafiq Azzam, President IAEG and Dr. Faquan Wu, Secretary General, IAEG
and many other IAEG council members have consented to come to India during that time. I expect a renewed initiative on the collaborative activities between ISEG and IAEG will emerge during the
Dear colleagues,
It gives me immense pleasure to put forward the April-October 2019 combined issue of ISEG News. With the announcement of the election for the new council, this is perhaps the last issue published by the present council. The election process is scheduled to be completed by 15th Jan 2020. On 18th Jan 2020, new ISEG Council will take over.
It has been a stupendous experience for me as Secretary, ISEG. The constant encouragement from the President and invigorating support given by all council members, espec ia l ly my Jo in t Secretaries, Editor and Treasurer have given me continuous strength to congeal my efforts for the development of the
society.
As you all are aware, India along with its co-host neighbouring Nations will be organising 36th International Geological Congress (36th IGC) in Delhi, India during 2-8 March 2020 after 56 years.

An article on ―In-situ Geotechnical Site
Investigations‖ by Dr. D.S. Subrahmanyam
published in this issue reveals the innovation
adopted by NIRM in various in-situ rock
mechanics testing. This article is being
published as a three part series. An interesting
article on ―Geostatics‖ by Sh. Saikat Pal very
vividly describes the emerging application of
Geostatics in Engineering Geology. I‘m sure
this will enlighten many young professional
engineering geoscientists, who will adopt this
tool for the betterment of Engineering Geology
in the country. This issue also carry a
Biography on Prof. Quido Zaruba, who despite
of being a professional Civil and Construction
Engineer gave rightful importance to engineer-
ing geological investigations. His understanding
of geology and its impact on civil construction
was remarkably prodigious. Even today‘s
construction engineers and geologists need to
learn a lot from his works. Contributions from
Dr. Ranjan Dahal of Nepal regarding IAEG
activities and Dr. Gopal Dhawan w.r.t.
geotechnical training program are sincerely
acknowledged. I‘m deeply indebted to all the
authors for their valuable contributions and
hope our readers and distinguished life
members shall cherish this issue as well.
The process of digitization of Journal of
Engineering Geology is being done. Several
previous issues have already been uploaded
on our website www.joegindia.com. Hoping
that the new team will bring more laurels to
ISEG. Bye!

Dear Members,
――Exuberance is beautiful‖ - William Blake
We may have accomplished less, but whatever
we could do, we did with high spirits and great
fervour. Euphoria of serving the ISEG is
endless, but like many beautiful things, our
tenure is also fixed. Now as the curtain falls,
with all gratitude we could give a sigh of bliss!
ISEG Executive council for the term 2018-19
has been distinctively unique and highly col-
laborative. Being the Editor, the enormous
cooperation and support I received from our
Hon‘ble President, Prof. K.S. Rao and most
dedicated Secretary, Dr. Saibal Ghosh has
been exceptional. Prof. Rao took out very
precious time from his very busy schedule and
discussed in detail the improvements we could
make in ISEG publications especially the
journal. Many amelioration steered under his
able guidance shall bear the fruits till a long
time to come. Similarly, Dr. Ghosh in spite of
his hard pressed commitments towards IGC
2020 gave significant time to the publication
matters. His faith and trust towards the
editorial team kept us sailing even in rough
waters. Words cannot elucidate the gentleness
and promptness of Dr. Mridul Srivastava,
Treasurer ISEG. In spite of his official
commitments, he never relinquished from his
responsibilities and made prompt payments to
clear ISEG bills. On behalf of my Editorial
team, I convey my regards to all distinguished
Executive Council Members including Past
Presidents Dr. Gopal Dhawan and Shri R.N.
Misra for their constant guidance and support.
It is for the first time ISEG is presenting a
combine issue for April-October 2019. Beside
regular features, this issue carry articles
which are very noteworthy, eloquent and
impactful. They have a conspicuous
message for the upgradation and improve-
ment in the engineering geology techniques.

NHPC’S 2000MW SUBANSIRI LOWER PROJECT RESUMES CONSTRUCTION
A Memorandum of Agreement (MOA) has been signed between
Government of Assam and NHPC Limited for implementation of 2000
MW Subansiri Lower Hydroelectric Project on 23rd August 2019 at
Guwahati, Assam. Shri Niraj Verma, Principal Secretary (Power)
signed the MOA on behalf of Government of Assam and Shri Balraj
Joshi, CMD, NHPC signed the MOA on behalf of NHPC.
Shri Janardan Choudhary, Director (Technical), NHPC, Ms. Syeda
Hasina Murshid Rahman, Secretary (Power), Govt of Assam, Shri A.K
Mishra, Managing Director (NHDC), Shri Arvind Bhat, Executive
Director (Subansiri Lower Project) and other senior officers from
NHPC and State government were also present on the occasion.
Subansiri Lower H.E. Project is the largest Hydro Project of the
country, presently under construction with an installed capacity of
2000 MW and annual generation of 7421.59 MU and is located on the
border of Assam & Arunachal Pradesh. Being a part of the cascade
development conceived by Brahmaputra Board, the Project would also
afford relief from floods by moderating the flood in Subansiri river.
NHPC has undertaken protection works along both the banks of
Subansiri river in the downstream area for containing flood water and
checking soil erosion.
NHPC is also implementing downstream developmental works which
inter alia includes livelihood intervention and infrastructural
developmental works. Construction of the Project will bring an overall
development in the area and give a fillip to the overall economy.
It is pertinent to mention that the construction activities of the
Subansiri Hydroelectric Project has been stopped since 2011 due to
agitation by some pressure groups. After a number of committees
appraised the project and suggested remedial measures, all the
technical apprehensions stand assuaged and legal hurdles cleared.
NHPC resumed the construction work of the Project and is fully
committed to complete the Project with the support of local people

stress concentrations along the borehole walls. The in-situ stress
field is also important for fracturing the formations of oil and gas
fields to enhance the production. Hence, the Knowledge of in situ
stresses is fundamental to many studies in earth sciences.
Geotechnical Engineering Department of NIRM is having vast
experience in this field and stress measurements were conducted
for the needs of industry for the last 28 years. The significant
achievements are highlighted as under.
Highlights
a. The Stress Map of India has been prepared and periodically
updated for quick and reliable information regarding stress
directions at various places of India. This is a significant
contribution towards World Stress Map. The database that
is available from Stress map of India will not only be helpful in
academic researches but also for commercial and economical
investigations. In academic research, this data will contribute
to determine the possible movement of plate tectonics.
b. A new technique has been developed to measure the in-situ
stresses using manipulation of flow rate in fractured and
porous rock mass. This technique would be helpful in
conducting the stress measurements in fractured rocks
especially in Himalayan terrains where the rock mass is gener-
ally porous or highly fractured.
c. Due to highly fractured nature of the rocks in the Himalayas,
the normal hydro fracturing tool is ineffective due to longer
length of the injection unit of the hydro fracturing tool. A
special site specific hydro fracture tool is designed and
developed as an innovative method to address this problem.
d. Online, real time mobile app has been introduced to know
the quick result of magnitude and direction of stress in the field
itself.
e. Stress measurements are conducted at various hydroelectric
project sites at the depth of 350 m from the surface at
Himalayan areas and at 600m depth from surface in Coal
mines.
f. Geotechnical Engineering Department of NIRM has applied for
obtaining Patent rights from Controller General of Patents,
Designs & Trademarks, Govt. of India for the following and the
content has been published along with preliminary
examination.
i. In-situ stress measurements in fractured rock mass by using
high flow rate technique.
ii. In-situ stress measurements in porous rock mass by using
high viscous liquid.
The in-situ Geotechnical investigations are an essential and integral
part for the design of any engineering structure. Geotechnical
engineering department of National Institute of Rock Mechanics
(NIRM) with its experienced manpower and state of the art
equipment is actively involved in numerous projects both in India
and its neighbouring countries. Around 211 sponsored projects in
different areas of construction viz., hydroelectric, irrigation, railway,
mining, petroleum, atomic and nuclear sectors are completed in the
last 30 years of the establishment of this Division at NIRM.
The in-situ geotechnical investigations carried out are viz.,
In-situ stress parameters determined by Hydro fracturing
technique (HTPF method) up to 600m depth from the surface
In-situ deformability parameters determined by Plate load test
method and Plate jacking method as per ISRM and ASTM
standards.
In-situ deformability parameters determined by Goodman jack
and Pressure meter methods inside the boreholes.
Plate bearing capacity and Foot load tests as per ISRM and IS
standards
Modulus of Subgrade Reaction of Soil as per ISRM standards
Acoustic Borehole Tele viewer to scan the boreholes up to the
depth of 600 m for studying the various features of rock mass.
In-situ stress
The distribution of In-situ stresses in terms of magnitude and
orientation affects the geometry, shape, dimensioning, excavation
sequence and orientation of underground openings/mines. Some of
the design solutions in hydroelectric projects require in-situ stress
measurements depend on the ability of the rock formation to
support the excavation, the acceptable water pressure in the
conduits and best orientation for different components of the power-
house complex. In room and pillar mining, stresses in pillars affect
the overall mine extraction ratio, the overall mine stability and
layout. In petroleum industry borehole stability is controlled by

It is universally known that, the engineering properties of earth
materials are heterogeneous, varying from location to location.
Unfortunately, in almost every geo project, the volume of samples
assimilated for characterizing these materials constitutes only a
insignificant fraction of the volume of material that affects
engineering judgement. Engineering Geology revolves around its
never ending struggle to deal with large uncertainties and variations
in material properties. Either for the sake of simplicity or for lack of
appropriate tools, engineers often assume properties to be the
same throughout a domain. It is however well known that use of
averaged parameter values can lead to conclusions, which
significantly differ from actual behaviour. For an example,
measurements of strength of rock at different boreholes or from
different depth of same borehole tend to give wide variation of
values. In order to design on basis of a single value, the arithmetic
mean is considered. Since arithmetic mean does not consider the
frequency distribution, it may not represent the data at any
particular location. A weighted average would give better reliability
in this case.
More often key decisions with major implications on cost and time
of the project have to be made on the basis of the sparsely
sampled data. It is obvious that this affect the health of the project
frequently leading to contractual complications sealing fate of the
project.
With this background, it could be easily realized if we could not
increase the quantity of information we should try to at least raise
the bar on quality of the interpretation of available information.
More accurate knowledge of the spatial distribution of material
properties promotes safe and economic design. It facilitates more
accurate interpretation of ground conditions based on the sparse
information that characterizes engineering geological investigations.
Here comes the role of Geostatistics, which is spatial attribute
coupled with normal statistical distributions of data. It is based on
assumption that there is some connection between location and
data values. This enhances the information captured from sparse
and often under-sampled data and ultimately it predicts probable
distributions of properties in space. In the constant strive to combat
the challenge of this uncertainty; several practitioners have relied
upon the arsenal of Geostatistics.
Among many other benefits, geostatistical analysis can offer the
following to engineering geology (Hammah & Curen):
Techniques for optimizing sampling locations so that maximum
information can be obtain at minimized cost, and
Methods for estimating engineering properties at different
locations with minimum estimation error.
Powerful tools for forming relatively simple, yet accurate,
models of inhomogeneous material based on limited sample
data
Optimization of Site Investigation Locations
It is to be borne n mind that aim of geostatistics is not to
substitute investigations but to optimize the output of predefined
quantum of investigation. Suppose an amount ‗x‘ is allocated for
project investigation. Out of which amount ‗y‘ had been utilized in
first round of investigation. Now how to make best use of
remaining amount (x-y)? A very useful geostatistical analysis is
the contour plots of the standard deviations of predicted values at
non-sampled locations– the higher the standard deviation the
greater the uncertainty. Accordingly, engineering geologists could
acquire additional samples from these locations to substantiate
the understanding of conditions.
Estimation of engineering properties
Geostatistics aims towards searching the relationship between the
properties and space. The spatial continuity of the random
variables is described by a model of spatial continuity that can be
either a parametric function in the case of variogram-based
geostatistics, or have a non-parametric form when using other
methods such as multiple-point simulation or pseudo-
genetic techniques.
In pursuit of spatial distribution, the interrelationship between
related and important properties could also be derived using the
correlation coefficient between them. For instance, correlation
coefficient between aperture and persistence of discontinuities in
project area, would help in key decisions on grouting material and
hence the cost estimate.

QUIDO ZARUBA
Prof. Quido Zaruba, recognised and respected worldwide as the ―founder of the Czechoslovak
engineering geology‖ was born on 18th June 1899 at Ceske Budejovice. He graduated from the
Faculty of Civil Engineering, Czech Technical University in Prague where he defended his degree
in Doctor of Technical Sciences (Dr.Tech) in 1926. Subsequently, in 1931he acquired a second
doctorate in geology at Faculty of Natural Sciences of Charles University, Prague. In 1936, he
completed his post doctoral thesis dealing with highways and tunnel construction.
Prof. Zaruba‘s father was also a civil engineer and building developer who started his construction
firm in 1898. Working in his father‘s construction business, he recognised the importance of
geology in civil engineering. From his father, he inherited an interest in the scientific work, leading
him to study the effects of geological processes on the geotechnical conditions of construction. He
published several papers on some of his experiences at large construction sites.
When Zaruba took over the reigns of his father‘s business, he established a department of
geological investigations for construction planning in his firm. At that time, it was a pioneering
act, a direction in which only few construction companies had ventured. He believed that project
planning and construction needs to be preceded by extensive geological survey. This serves in
completing the foundation of the construction in a timely manner thus avoiding potential risks, an
indispensable fact, which the construction industry worldwide understood very lately. As a young
engineer, he bought Swedish drilling rigs for his department and set up laboratory for newly
emerging soil mechanics. He used to keep a company archive with a filing cabinet of important
sites, a description of drilling profiles and handwritten geological records and drawings. Over the
years, the original company grew into a large enterprise which built very important railway line
from Czech lands to Slovakia including several railway tunnels. The company was nationalized in
1948 when his geological investigation department became the foundation of Institute of Building
Geology, Geographical Surveys and Probe. The original Zaruba company was in 1989 privatized to
Stavebni Geologie and later on merged with Dutch multinational group ARCADIS to form ARCADIS
-Geotechnika.
At the age of 32 itself, Zaruba was appointed as Assistant Professor at Charles University. After
the post-war reopening of Czech Technical Universities in Prague during 1945, he was entrusted
with laying the foundation of geological institute at the Faculty of Civil Engineering and shortly
afterwards he was appointed as full time professor. After establishment of Czechoslovak Academy
of Science in 1952, he was appointed a correspondent member and later an academic. This
enabled him to establish an R & D centre for engineering geology in 1957, which later became
part of the Institute of Geology at Czechoslovak Academy of Science. Time and again Zaruba had
proved to the construction industry that engineering geology is a field directly connected with the
site practices. Therefore, he was often called upon both at home and abroad to seek his advice
for securing the construction sites from geological difficulties. He used his practical experiences
for teaching also.
In 1964, at the International Geological Congress held in New Delhi, a group of engineering
geology pioneers proposed to establish the IAEG. Quido Zaruba was one of them. The first
general assembly of the IAEG was organised in 1968 at Prague, where he became its first elected
President for the period 1968-1972.His support in the development of IAEG during its formative
years was invaluable. He also played an important role in the publication of IAEG Bulletins.
Prof. Zaruba had an exclusive interest in the geological problems associated with dam founda-
tions. He assisted during construction of several major dams in Czechoslovakia and Europe. He
was also involved in tackling geological problems encountered during tunnel construction includ-
ing Prague subway system as an expert. His experience at construction sites of rail, roads and
dams, mostly in Flysch zone of Carpathians, led him to introduce his own classification of land-
slides. Based on his experiences with several building collapses due to mass movement, he pub-
lished a book "Landslides and their Control‖ in association with V. Mencel.

BIOGRAPHY
Prof. Zaruba has written several books on engineering geology. One of his book ―Landslides and their Control‖ published during 1969 got translated into several languages included Japanese. This book contained most comprehensive geological classification of landslides along with various rock mechanics methods used for stress measure-ments. It evaluated various methods of stabilizing landslides, giving examples from practice.
Richard E Goodman in his review of this book published in SCIENCE of May 1970 issue wrote: ―The book is a complete study of enormously interesting subject of landslides, including not only those slides produced in the natural terrain and considered as geologic phenomena but those produced by man and his activities as well. It is very well written from both the geological and engineering point of view and is thorough in both fields to a degree seldom achieved in a single work.‖

Prof. Zaruba died at the age of 94 on 8th September 1993. He was
more than just a teacher- he knew the life stories of his pupils; he
was able to talk to them about their problems, often helping them
with their life decisions. In his honour since 2001, Quido Zaruba
Prize for young engineering geologists and geotechniques has been
constituted. Zaruba‘s professional career has firmly entrenched his
close relationship with nature. As a construction engineer himself, he
took cognizance of the inappropriate technological interventions in
nature long before environmental issues were in vogue. His students
spread all around the globe are loyal to their teacher‘s principles and
procedures.

Probability of Geostatistics in Engineering Geology
The application of Geostatistics in engineering geology has a low
frequency of distribution with exception like Channel Tunnel
project. Geostatistics deemed to be among the many factors that
made the success story of Channel Tunnel project possible, where
geostatistics has enabled the careful assessment of geological
risks, and was used to optimize the alignment of the tunnel.
At the end let‘s go back to the beginning. Why are using the
terminology ―emerging‖ in case of Engineering geology, when it is
―established‖ through decades of use in Mining geology and
Petroleum geology? There is an argument that although
geo-mechanical properties show spatial correlations, rock mass
quality is strongly related to its geological and structural history.
But the same is holds good for ore geology and petroleum geolo-
gy as well.
The inner lying cause may be more of manual than geological.
The reluctance of usage of geostatistics by engineering geologists
may be attributed to their unfamiliarity with the subject. And the
familiarities will begin only through a belief that there is very
strong positive correlation between geostatistics and recurrence
rate of success in engineering geology!

GEOSTATISTICS - AN EMERGING TOOL IN ENGINEERING GEOLOGY
Simulation and Numerical Modelling
Geostatistical simulation can help engineering geologists assess
the risks posed by uncertainty. Such simulation can produce
many, equally likely, spatial representations of a parameter in a
manner consistent with values observed at sampled locations and
with in situ variability.
Using geostatistics, element properties can be assigned in a man-
ner that realistically reflects heterogeneity at a site. Studies have
shown that the results of such analyses can differ substantially
from those obtained from conventional computations, which use
simple averaged values.
Methodology
The simplified steps involved in geostatistical studies are
essentially:
i. Exploratory spatial data analysis- through sampling and
testing of data at different locations
ii. Spatial correlation through process like Variography
iii. Prediction or Interpolation of data through process like Kriging
iv. Validation –This evaluates whether the property is over or
under estimated.
