This document classifies canals based on several factors: - Permanency (temporary or permanent) - Size (main canal, branch canal, major/minor distributaries, water courses) based on discharge rates - Alignment (watershed, contour, side slope) - Lining (lined or unlined) - Purpose (irrigation, power, navigation, water supply, feeder, carrier, multipurpose) - Financial returns (productive or protective) It provides details on the definitions and characteristics of each classification.

2. A channel filled with water and designed for
navigation, or for irrigating land, etc.
An artificial watercourse or extensively modified
natural channel used for inland water transport and/or
the control and diversion of water for drainage or
irrigation

3. Classification based on
a. permanency
b. Size
c. Alignment
d. Canal surface
e. Purpose
f. Financial return

4. CLASSIFICATION BASED ON PERMANENCY
1. Temporary canal1. Permanent canal

5. (BASED ON DISCHARGE)
MAIN CANAL
BRANCH CANAL
MAJOR DISTRIBUTARY
MINOR DISTRIBUTARY
WATER COURSE OR FIELD CHANNEL

6. Main Canal takes off directly from the upstream
side of weir head works or dam.
Usually no direct cultivation is proposed

7. All offtakes from main canal with head discharge
of 14-15 cumecs and above are termed as branch
canals.
Acts as feeder channel for major distributaries

8. All offtakes from main canal or branch canal with head
discharge from 0.028 to 15 cumecs are termed as major distributaries.
All offtakes taking off from a major distributary carrying
discharge less than 0.25 cumec are termed as minor
distributaries
Small channels which carry water from the outlets of a
major or minor distributary or a branch canal to the fields to
be irrigated.

10. Based on alignment
1. Watershed canal
2. Contour canal
3. Side slope canal

12. (Based on Lining being Provided or not)
1. Unlined canals 2. Lined canals

13. An unlined canal is the one which has its bed and banks
made up of natural soil through which it is constructed and not
provided with a lining of impervious material
A lined canal is provided with a lining of
impervious material on its bed and banks to
prevent the seepage of water

14. 1.Irrigation canal
2.Power canal
3.Navigation canal
4.Water supply canal
5.Feeder canal
6.Carrier canal
7.Multipurpose canal
Classification based on purpose

15. 1. Productive canals
2. protective canals
Classification based on financial returns
