Carrier canal
Feeder canal
Main canal
Navigation canal

Side slope canal
Ridge canal
Field channel
Which type of canal is supplied with water only during flood periods and has no headworks?
Permanent canal
Inundation canal
Protective canal
Productive canal
Which canal can irrigate fields on both sides and generally does not require cross-drainage works?
Contour canal
Side slope canal
Ridge canal
Branch canal
A canal constructed through hard soil or disintegrated rock with high permissible velocity is called:
Alluvial canal
Lined canal
Non-alluvial canal
Branch canal
Which lining material provides nearly 95% seepage control in irrigation canals?
Brick lining
Clay puddle lining
Cement concrete lining
Asphaltic lining
In contour canals, irrigation is possible only on one side of the canal (a)
Inundation canals are provided with permanent head regulators (a)
Assertion (A): Ridge canals are considered the best alignment for canals. Reason (R): Ridge canals minimize cross-drainage works and irrigate land on both sides.
Both A and R are true and R explains A
Both A and R are true but R does not explain A
A is true and R is false
A is false and R is true
An artificial channel constructed to carry water to the fields is called a (a) .
The canal aligned nearly parallel to the contour lines is called a (a) canal.
A permanent canal may be either (a) or non-perennial.
The channel that ultimately supplies water to fields is known as a (a) .
A canal constructed through river-deposited soils is known as a (a) canal.
