India's Water Grid & South Asian Waterways By AB Thapa It has been recently
reported in Indian news media that the
Government of India is considering to launch
a grandiose project to link all the
main rivers flowing in their territory.
From the engineering view point it indeed
is a big challenge. The Ganga-Cauvery
link considered since a long time involves
a pumping lift of about 400 meters
for delivering water across the Vindhya
mountain. So a very short period
diversion of flood season surplus flow
from the Ganges basin to Cauvery
might prove to be very costly. It would
be necessary to provide desanding structures,
canal and the capacity of the pumping
station virtually unprecedented in size. Dr.
K.L. Rao then Minister of Irrigation and
Power Govt. of India, who was the main
architect of this grandiose project,
perfectly knew about the great
difficulties that lied ahead. He has clearly
written about it in his books. Dr. K.L. Rao's Proposal In view of the
unprecedented size of the scheme and the
complexity, magnitude and cost of the studies
required thereof, it was considered advisable
to consult international experts before embarking
on the investigations. India had sought the
advice of the experts to obtain a second
opinion on the feasibility of the scheme based
on the preliminary studies made by that time.
Apart from evaluating the socio-economic benefits
of the scheme on a rational basis the
experts assigned to this project indicated the
further studies and surveys and investigations
needed to be undertaken. The UNDP
was involved in conducting the study. A
team of UN experts had visited India in
December 1971 and in March 1972 to study the
problem and submit its report. The UNDP
mission had observed that the National Water
Grid is technically feasible and presents no
insurmountable engineering or construction problems,
but requires continuing study and refinement
over a very very long period. The
feasibility of the WATER GRID project
would very much depend on the
availability of cheap electricity for pumping. Govt. of India's
New Policy Dr. K.L. Rao had written
that it would take a very long time
to carry out the investigation to plan
the India's Water Grid Project. He has said
that India had to plan now for succeeding
generations of the second India - India of 21st
century. Nevertheless, this project was
not accorded great importance. The studies were
going on at a very slow pace. However,
now the Government of India appears to
be decided to launch this highly ambitious
project with renewed vigor and determination.
It seems the President of India A.P.J. Kalam
revived this idea in his Independence Day
address to the nation last year. It is
about time now that in the light of
Indiaís recent policy to link rivers in
their territory we also make afresh
assessment of our water resources. Information
provided in the Indian news media clearly
suggests that the Government of India is
now engaged in developing a policy to
obtain the consent of Nepal, Bhutan and
Bangladesh through a revenue sharing agreements.
It is obvious that the Indian experts
conducting the study would have
found the role of Nepal to be crucial
for this type of linkage project to succeed. Sir Arthur Cotton's
Plan Needless to say that
most of the projects to be included under
the India's Water Grid Plan would be
under study for a very long time.
Moreover the feasibility of various individual
projects would have to be established before
taking the decision to implement any of
them. Availability of surplus water even during
the wet season in the Ganges basin
would remain as the most serious
constraint. Nevertheless it would have
been very interesting to conduct the
study to provide WATER GRID to develop
inland waterways as proposed by the Sir Arthur
Cotton in the nineteenth century. Such
waterway development plan could also
include nominal water transfer component. Sir
Arthur Cotton's plan could be extended to
cover India, Pakistan, Nepal and Bangladesh by
a network of inland waterways for the
transportation. For planning this type of
waterways, we can learn a
great deal from the past experience
of the Europe which has now been
covered by a dense network of
waterways that connect each country with
the Baltic, North Sea, Bay of Biscay, Meditarrinean and
the Black Sea. Sir Arthur Cotton had
developed the concept of an extensive
navigation plan more than a century ago.
His plan included the building of canals
to link major rivers and tributaries. He
had proposed a north-west coastal canal running
from Bombay to Indus, waterway from Calcutta
via Hooghly and Ganga to Cawnpur, waterway from
Allahabad via Chambal, Narmada,; Wainganga to
Godavari etc. Early European
Experience In Europe the canal
navigation era started towards the end of the
17th century. France took the lead integrating
its national waterway system further by
forging the missing links. In the north
the Saint-Quentin Canal, with a 3.5 mile tunnel,
opened in 1810, linking the North Sea and
the Schelds and Lys systems with the
English Channel via the Somme and with
Paris and Le Havre via the Oise and
Seine. The Rhine- Rhone Canal, opened in 1834, provided a direct
north-to-south route. The Sambre-Oise Canal linked the
French canal system with the Belgian network via the Meuse.
In Germany in the late
17th and early 18th centuries the three
great rivers, the Elb, Oder, and Weser, were linked
by canal. The Ludwig Canal, forming part of
the Rhine-Main-Danube route, was opened in 1840. A
nationwide Russian canal system connecting the Baltic
and Caspian seas via the Neva and Volga
rivers became navigable in 1718. In the 19th
century Russia made connections between the heads
of navigation of its great rivers, the Volga,
Dnepr, Don, Dvina, and Ob. Importance of Inland
Waterways Despite modern technological
advances in air and ground transportation, inland
waterways continue to fill a vital role
and, in many areas, to grow substantially. The
ongoing construction of the giant Three Gorges
project in China expected to
further develop Yangze river navigation
and recently in 1992 the completion of
the construction of the Main-Danube link canal
can also be cited as the most
recent examples of the continued
importance of the inland navigation. For
many types of commodities, particularly such
bulk commodities as grains, coal, and ore,
inland waterway transport is still far
more economical than any other kind of
transport. Although very large capital investment is
required to modernize existing inland waterways
systems and for new construction, water
transport has demonstrated competitive strength as
a carrier for commodities in the movement
of which the time factor is not of
prime importance. Thus, it is hardly surprising
that modernized inland waterways, using the latest
navigational aids and traction methods and
traversing the great landmasses of North
America, Europe, and Asia, play an
important economic role. New Navigation Canals The primary physical
restriction is that vessels cannot travel
through water at speeds possible for road
vehicles or railway wagons. Waterways must
provide larger tonnage units than those possible on
road or rail in order to be competitive. Modern
waterway engineering, therefore, is directed towards
provididng channels suitable for larger vessels
to travel faster by reducidng delays at locks
or from darkness and other natural hazards. In
the last century existing small canals were
upgraded and many new canals much
larger in size were built in Europe. In
Germany the 467 km long Mittelland Canal was
opened in 1938 that completed the east-west
link in a system of about 11,265 km of
inland waterways, extending from the Dortmund-Ems Canal
east of the Rhine to the Elbe north of
Magdeburg. The Nord-Sud Canal (or Elbe-Seitenkanal) was completed
in 1976. This canal leaves the Elbe about 20 miles above Hamburg
and, running south, joins the Mittelland Canal near
Wolfsburg, reaching a total of 71 1/2 miles and
shortening the route between Hamburg and the Ruhr by
134 miles. The Main-Danube canal connecting
the Rhine with the Black Sea was
completed in 1992. France's many of the
low capacity canals are being raised to the
1,350-ton standard. A major development
planned in the 1970s in cooperation with West
Germany was the construction to this standard
of the North Sea-Mediterranean waterway via the
canalized Rhone and Rhine rivers. The Rhine has
been navigable between Basel and Rheinfelden since
1934. In The Netherlands the extensive canal system based on
large natural rivers and serving the ports of Rotterdam
and Amsterdam has required relatively small
improvement. The Juliana Canal was built in
1935 to bypass the Meuse River between
Roermond and Maastricht and it was further
improved after Second World War. The Twente
Canal opened in 1936. In the former Soviet
Union navigation played a major role in
the country's economy. The Volga-Don Canal, 63 miles in length,
was completed in 1952. The Moscow-Volga Canal, built
between 1932 and 1937, runs 80 miles from the
Volga to the Moskva River at Moscow.
Among other important navigation canals are
the 127-mile canal connecting different
systems enabling to link Baltic with the
Black Sea, the White Sea- Baltic Canal built between
1931 and 1933. Economy and Size
of River Crafts With the development of
rail transport in the 19th century, canals declined
as the dominant carriers of freight in the
United States and Britain. In continental
Europe such adverse impact was not noticeable
because the navigation canals in Europe
were larger in size. Wherever the
canals were small, they
were enlarged. To meet competition from road
transportation, with its greater flexibility and
higher speeds, water transport has in its
advantage the capacity for larger units thus
there was tremendous rise in size of
the vessels. As a result, the 300-ton
barges operating economically early in the last
century have been replaced by crafts as large
as 1,350 tons and more. In Europe, push tows normally
operate with fewer than six barges, but on the
Mississippi, with its deep channel, a push tow
may aggregate 40,000 tons, an assembly of 40 barges
being controlled by one 9,000 horsepower push tug. On
the Ohio River the original 600-foot lock
chambers were lengthened to 1,200 feet to
obviate double lockage. The development of
canal waterways continued in Europe and
North America in 19th and 20th centuries
also. The coordinated and
combined use of inland water transportation
and the maritime transport to carry
barges abroad oceangoing vessels in the so
called Barge Carrier System can be
of great interest to industrial centers
deep inside the mainland. This system
eliminates one or more transfer-handling operations
in the movement of cargo from the
point of origin to its final destination. Cargo River Coasters (CRCs) can operate in
inland waterways as well as in the open seas. Following the recent ESCAP study of the
Ganges Navigation, the Kosi Navigation Canal could be used to operate CRCs even from
Nepal to other ports beyond Haldia. Such possibility would be a dream come to true
for a landlocked country like Nepal and various river
port cities of the South Asia located
far away from the seaports. Vision, Mission, SAARC
and Waterways It can hardly be
denied that for peace and development
there is a need to have a vision
of a new South Asia where the SAARC
would be playing more dynamic role
towards greater unity among its member
countries. More than a decade ago Jacques
Delors, president of the European Commission
(the European Communities' 17-member executive body), had
advised member governments of the EC either
to speed up their integration or be bypassed
by the history; in fact, they opted in
1990 for bold steps towards greater unity. Now
the SAARC is also facing the same
type of challenge. The SAARC should now
try to identify the fields the most
appropriate for its involvement at the present
time. A study to develop a
very long term vision to provide a
grandiose network of waterways like in Europe
to cover India, Pakistan, Bangladesh
and Nepal does not appear to
be inappropriate for an institution like
the SARRC to be associated. |
