The islands Buddhist civilization
produced skills of hydraulic engineering capable of building
some of the largest man made irrigation works in the world.
Many still provide water to the thousands of acres of
paddy fields an urban need. The skills of our engineers
in this branch is clear from the historical evidence such
as the invitation made to Sri lank an Engineers in the
8th century by a Kashmir kin to form a lake in his Country.
Our ancestors more than 3000 years ago has seriously considered
this concept of water storing and delivery. It is evident
from the gigantic reservoirs like “Parakrama Samudra”,
“Kalawewa”, “Minneriya”…. etc and canal systems of Elahera,
Yoda Ela…etc. Unfortunately due to he invasions since
the Anuradhapura Era up to British period and epidemics
caused all the development and technical skills of went
in to wilderness. As a result Sri Lanka had to implement
a new agriculture development program n the 19th century
as a new enterprise.
