UNIT
- A Design of Major structures on Main Canal and Combined
Structures on
Branch canals:
This unit
deals with the work of design of the major structures on Narmada
Main Canal and combined structures like cross regulator with
bridge, cross regulator with fall and bridge, cross regulator
with canal siphon, cross regulators with canal falls and canal
siphon etc of branch canal and sub branch.
This unit
also deals with the proposal of Micro-Hydel Power Stations
to generate energy at the location of the cross regulator
combined with fall. Detail Project Report prepared by AHEC
Roorkee for proposal to set up Micro Hydel Power Station at
10 different location of CR/Fall on Branch canals-7 on Miyagam
branch canal and 3 on Saurashtra Branch Canal are scrutinized
by this unit.

of work
(A)
NARMADA MAIN CANAL
The Narmada
Main Canal (NMC) would be 458 km. long up to Gujarat-Rajasthan
border. Its capacity at the head would be 1133 cumecs (40,000
cusec) and will taper down to about 71 cumecs (2500 cusec)
at the Gujarat-Rajasthan border. The cross section at its
head is 73 m. (240 ft.) bed-width and 7.6 m. (25 ft.) full
supply depth.
The canal
in its journey up to Rajasthan border will traverse through
regions with diverse agro-climatic and soil characteristics
and crosses numerous streams and major rivers. In all 594
structures of various type viz. cross-drainage works, canal
crossings, regulating and control structures, are proposed
to be constructed along the main canal.
Phase-1
(NMC Ch.0 km. to 144.5 km.)
Narmada
Main Canal works of Phase-1, i.e. from Main Head Regulator
(Ch. 0.0km) to Mahi River Crossing (Ch. 144.5km) is completed.
The canal is operative since October 2002. Total 13 structures
in this reach are dealt by this unit. Out of 13 structures,
six major structures are designed by consultant and scrutinized
by this unit. The remaining all the structures are designed
by this unit. The types of structures in this reach are different
viz. Drainage culvert, Canal Syphon, Syphon Aqueduct, Aqueduct
etc. The canal syphon and aqueduct are major structures in
this reach.

Phase-II
(A) 144.50 km to 263.00 km
In this
reach, all seven major siphon structures i.e. Canal Syphon
structures are completed. The design of all the canal syphon
structures is designed by this organization except Sabarmati
Canal Syphon. Sabarmati canal siphon is designed by design
unit of Central Water Commission (CWC), New Delhi. The design
of this structure is carried out by exchanging the technical
aspects among CWC and this Organization.
