Question

Why are inundation canals being converted to perennial canals? Give two reasons.

Answer 1

Hint: Inundation canals are long canals that are taken from large rivers having a huge capacity and receive water when the level of the river is high enough and especially when in flood. Perennial canals are lined to dams and barrages to provide water throughout the year, they are also used for irrigation purposes.

Complete answer: A canal is a waterway channel for water conveyance or for water transportation. They are also called artificial waterways and can also be used for irrigation purposes. It is an artificial version of a river. Canals can be divided into two types on the basis of their usage:
- Waterways: Canals used for vessels transporting goods and people.
- Aqueducts: These are water supply canals that are used for human usage, irrigation, and power generation.
Canals can also be divided on the basis of the water capacity and their water resource:
- Inundation canals
- Perennial canals
Inundation canals are long canals that are taken from large rivers having a huge capacity and receive water when the level of the river is high enough and especially when in flood. Perennial canals are lined to dams and barrages to provide water throughout the year, they are also used for irrigation purposes.
The inundation canals are being converted into perennial canals because the inundation canals become dry during the summer season and since these canals get water directly from the rivers they become dry when rivers change their course. Perennial canals have water in them all year through because they originate from a dam or reservoir. This is the reason why inundation canals are being converted.
