- Results into dry climate in Rajasthan
(Specially Western)
- Block the South West Monsoon Winds
- More Rainfall towards Western slopes

loamy, porous and MORE FERTILE than Bhangar
as new layers are deposited year after year during
floods.

WHAT IS THE NEED FOR IRRIGATION?
• RAINFALL in India is seasonal,
uncertain, uneven and sporadic.
• DIFFERENT CROPS have different
water requirements.
• It is indispensable in SEMI ARID
REGIONS of Gujarat, Andhra Pradesh,
Rajasthan etc.
• It is necessary to extend the frontiers of
cultivation in order to fulfill the food
requirements of a GROWING
POPULATION.
MODES OF IRRIGATION –
WELL (PRIMITIVE)
COMMON IN NORTHERN PLAINS
ADVANTAGES
Cheapest source of irrigation.
Can be dug at any convenient place.
Independent source of irrigation.
DISADVANTAGES
Fail to provide water during the dry summer months
Well can water only 1 to 2 hectares of land.
Time consuming.
In many parts it is brackish.
MODES OF IRRIGATION –
TANK (PRIMITIVE)
COMMON IN DECCAN PLATEAU
ADVANTAGES
Simple, easy & cheap
Stores rain water, prevents wastage
Helps in raising the underground water level
Also provide water for domestic purpose`
DISADVANTAGES
 Occupies large area which otherwise could have been
used for cultivation
 Many tanks dry up in the dry months
 Silting of tank is a problem
 Water is lost by evaporation
Reasons for the predominance of tank
irrigation in the Deccan region
Underlying hard rocks does not allow
percolation
The undulating surface forms natural
depression
Construction of well is difficult in the
peninsular region
MODES OF IRRIGATION –
INUNDATION CANAL (PRIMITIVE)
ADVANTAGES
Easily built
Cheap
Useful in controlling floods
DISADVANTAGES
Uncertainty of water supply
Only low lands areas are irrigated
Useful only during floods
MODES OF IRRIGATION –
PERINNIAL CANAL (MODERN)
ADVANTAGES
Perennial source of irrigation
Water rich in sediments
Although initial cost is high, it is quite cheap in
the long run
DISADVANTAGES
Leads to the problem of water logging if canals
are unlined
Problem of soil Salinization or ‘reh’
Marshy areas near canal become breeding
ground for mosquito resulting in Malaria.
Canal systems in North India
 Ganga Canal (GANGA RIVER, UP AND BIHAR)
 Nangal Dam Canal (SUTLEJ RIVER, PUNJAB AND HARYANA)
 Indira Gandhi Canal (SUTLEJ RIVER, DRY PARTS OF RAJASTHAN)
 Chambal Project Canal (CHAMBAL RIVER, MP AND RAJASTHAN)
Canal systems in South India
 Godavari Canal (GODAVARI RIVER, MAHARASHTRA AND AP)
 Tungabhadra Dam Canal (TUNGABHADRA RIVER, KARNATAKA
AND AP)
 Hirakud Dam Canal (MAHANADI RIVER, ORISSA)
 Periyar Project Canal (PERIYAR RIVER, TAMILNADU)
 Mettur Project Canal (KAVERI RIVER, TAMILNADU)
ADVANTAGES OF
MODERN METHODS OF IRRIGATION
More reliable.
Provide irrigation whenever needed.
Easy to operate.
Irrigate a much larger area.
Large amount of water can be pumped
by electric or diesel driven motor.
MULTIPURPOSE PROJECT
• Why is it so called?
Store water for irrigation
Generate electricity
Control flood
Provide afforestation in the catchment areas
Soil conservation
Provide drinking water
Use canal for navigation
Develop pisciculture
Develop recreational centre
CONSERVATION OF WATER RESOURCES
Need
• RAINFALL IS IRREGULAR AND
ERRATIC
• INCREASING DEMAND WITH
INCREASING POPULATION
• PER CAPITA WATER IN INDIA IS
VERY LOW
• AGRICULTURAL DEMAND
• WATER POLLUTION
How do we conserve water?
SPRINKLER IRRIGATION
-
NO LOSS OF WATER THROUGH EVAPORATOIN OR SEEPAGE
- EXPENSIVE
DRIP IRRIGATION
- Minimum loss of water due to seepage or evaporation
- Greater yield
- Reduces the chances of weeds
WATERSHED DEVELOPMENT
- Reducing surface run-off
- Recharging groundwater
- Irrigation
RAIN WATER HARVESTING
- Stored for future use
- Used to recharge groundwater
ADVANTAGES
