constructed across a river valley to form storage reservoir, known as storage
head works. Water is supplied to the canal form this reservoir through canal
regulator. The storage headwork is generally used to store the water.
Diversion Headwork:-
The works, which are constructed at the head of the canal, in
order to divert the river water towards the canal, so as to ensure a regulated
continuous supply of silt-free water with a certain minimum head into the
canal, are known as Diversion Head Works.
Objectives of Diversion Head Works:-
- To rise the water level at head of
the canal.
- To form a storage by constructing
dykes (embankments) on both the bank of river so that water is available
throughout the year.
- To control the entry of silt into the canal
and to control the deposition of silt at the head of the canal.
- To control the fluctuation of water level in the river during different seasons.
