 Frequent floods
 Receding glaciers
 Climate change
 Carbon credits
and to help predict where we are going, it is useful
to review where we have been

4. Kautilya
• Kautilya has described the procedure of construction of dams
for irrigation
• • The king should construct dams and canals in areas where
there is shortage of water.
• The dams may be built in partnership on hiring basis.
• If people participate in the dam building then they should be
given concession for purchase of land, wood etc
• The farmers should spare their servants and animals for
construction or share the construction cost.
• King should appoint an officer to supervise the fishing,
disposal of silt and floating objects(trees etc).

5. King Bhagirath – the first Irrigation
engineer of India
• Sir William Wilcox (The father of Irrigation Engineering) has praised
Bhagirath in following words
“Following the genius of your country, your ancient writers (Vyas in
Mahabharata) described the physical facts they were writing about in
spiritual language, but the facts were there all the same. Every Canal
which went southward, whether it has become a river like the Bhagirathi,
or remained a canal like the Mahabharata was originally a Canal.
They were lined out and dug fairly parallel to each other. They were
spaced apart that Canals should be placed. I remember quite well when I
began to line out a system of Canals for the irrigation of the country;
I was astonished to find everywhere that a so-called “dead river” on the
map was just where a canal should be place”

Closing remarks
• A number of concepts still need further
elaboration to achieve the level of design
quality comparable with more conventional
solutions and systems.
• For a number of systems more practical
experience is also still needed under
various hydraulic conditions.
• The realization of this need is only possible
if manufacturers, clients and researchers
cooperate closely.
