Flow irrigation and lift irrigation are two common methods used in agricultural practices to ensure the efficient distribution of water to crops. These techniques play a crucial role in maximizing agricultural productivity by delivering water to fields, promoting plant growth, and supporting overall crop development. This presentation provides an overview of flow irrigation and lift irrigation, highlighting their key characteristics, advantages, and applications.

FLOW IRRIGATION

2. IRRIGATION
The process of artificial application of water to the
soil for the growth of agricultural crops is
termed irrigation.

6. DEFINATION
Lift irrigation is a method of water supply that
involves pumping water from a lower source,
such as a river or well, to a higher elevation for
agricultural purposes, using pumps or mechanical
devices.

7. OVERVIEW OF LIFT IRRIGATION
Task A
first, to carry water by means of pumps or other way, from the water source to the
main delivery chamber, which is situated at the top most point in the command area.
Task B
they must distribute this water to the field of the beneficiary farmers by means of a
suitable and proper distribution. So that in Lift Irrigation system, the gravity flow of
water by canals or river is not available or used.
Lift irrigation schemes must accomplish two main
tasks:

8. PROCESS OF LIFT IRRIGATION
• The water is carried out by the help of pumps.
• The water is carried out from the water source at the
lower portion of the land.
• Mainly construction of dams and cannels are done
there.

12. OPEN WELL
Open Well-Open wells are used to extract water found
at the shallowest level in that area

13. SHALLOW TUBE WELL
Shallow tube wells are drilled to penetrate a shallow
aquifer and are usually less than 30 m deep.

14. DEEP TUBE WELL
A tube well called as such operated by a submersible
pump set or turbine pump coupled with a prime mover
capable of pumping ground water when the pumped
water level depth is more than 7 meters

15. REQUIREMENTS OF
LIFT IRRIGATION:
 Suitable and constant water source should be available for whole year at
the site of LIS. Water can be made available through Dams, Weir, River
canal etc.
 To lift water to the desired location, lifting medium i.e. pumps are required.
Depending upon the Duty point head, discharge the different types of
pumps are selected.
 main may be of steel, concrete or any other suitable material.

16. FLOW
IRRIGATION

17. DEFINATION
When water flows under gravitational pull through
the artificial canal towards the agriculture land, it
is termed as FLOW IRRIGATION
The following are the different system of flow
irrigation

18. INUNDATION
IRRIGATION SYSTEM
In this system, a canal excavated from the blank
of the inundation river (i.e. the river which overflow
in rainy season but nearly dried up in summer and
winter)
In the case water flow to the agricultural land in
rainy season only. INUDATION CANAL

19. PERENNIAL SYSTEM
OF IRRIGATION
In this system, a weir or a barrage is constructed
across the perennial river (i.e. the river which
flows throughout the year in its full capacity) to
raise the water level in the up stream side or a
dam is constructed to form a storage reservoir.
As with other methods of irrigation, perennial
irrigation has some sub-categories – Direct and
Storage.

20. ADVANTAGES OF LIFT IRRIGATION
Lift irrigation made irrigation possible at higher
level.

Land acquisition problem in L.I.S. is less.
Water losses are low.
Man power is less used.

21. ADVANTAGES OF FLOW IRRIGATION
✔ Flow irrigation systems are relatively simple to design, construct, and
operate.
✔ Compared to other irrigation methods, flow irrigation systems are often more
cost-effective, especially for small-scale or low-income farmers.
✔ Flow irrigation can be adapted to different topographies, making it suitable
for both flat and sloping fields.
✔ Since flow irrigation relies on gravity, it requires minimal energy inputs,
reducing operational costs.

22. DISADVANTAGES OF FLOW IRRIGATION
✔ Achieving uniform water distribution across the field can be challenging
with flow irrigation. Variations in soil properties, field slope, and channel
design can lead to uneven moisture levels.
✔ Flow irrigation can result in higher water losses due to evaporation, runoff,
and deep percolation if not managed properly.
✔ Flow irrigation often requires manual labor for the construction and
maintenance of channels, furrows, or basins, which can be time-
consuming and labor-intensive.
