Diversion scheme, comes under which type of irrigation system?

Explanation:

Direct Irrigation:

• In a direct irrigation system, water is directly diverted from the river into the canal by the construction of a diversion weir or barrage across the river without attempting to store water. This method is practiced where the river has an adequate perennial supply to feed the canal system during the times of crop periods.

Diversion-Based Irrigation or Diversion scheme:

• Diversion Based Irrigation (DBI) is a simple and cost-effective method, in this method we use slope or gravity (or gravitational force) to guide water from adjacent streams and rivers to the cropping field areas. It comes under a direct irrigation system.

Additional Information

Storage Irrigation:

• Storage irrigation is also known as tank irrigation. Tanks are small-sized reservoirs formed by small earthen embankments to store runoff for irrigation. The site is selected within a watershed protected by vegetation and containing a minimum of cultivated land so as to ensure a minimum rate of sedimentation which lowers its storage capacity. It is more popular in the peninsular region in the states of Karnataka, Maharashtra, and Tamil Nadu.

Flow Irrigation:

• When the water is available at a higher level, and it is supplied to the lower level, by the mere action of gravity then it is called flow irrigation.

Inundation Irrigation:

• Inundation irrigation is done by a canal taking off from a river in flood without any diversion work. It depends on the periodical rise in the water level of the river and the supply is drawn through open cuts in the river bank or creeks which are called heads.
