what were the ancient methods of irrigation found in different parts of India ?(5/3)
Answers
mohat or pulley
chain pump system
dhekhli system
rahat system
modern methods :
drip system
sprinkler system
1. Moat
Also called the pulley system, it involves pulling up water from a well or other such source to irrigate the land. It is an extremely time consuming and labour intensive system, but it is very cost efficient. Also, wastage of water is avoided when using a moat system of irrigation.
2. Chain pump
A chain pump consists of two large wheels connected by a chain. There are buckets attached to the chain. One part of the chain dips into the water source. As the wheel turns, the bucket picks up water. The chain later lifts them to the upper wheel where the water gets deposited into a source. And the empty bucket gets carried back down.
3. Dhekli
It is a system of drawing water from a well or such similar source. Here we tie a rope and bucket to a pole. At the other end, we tie a heavy stick or any other object as a counterbalance. And we use this pole to draw up water.
4. Rahat
So Rahat system of irrigation uses animal labour. Above the well, we tie a large wheel. An ox or cow would turn the wheel to draw the water from the well.
Modern Methods of Irrigation
These are more efficient systems of irrigation that were invented in the recent decades. These help us use water economically without wastage. Let us take a look at the two most important methods.
1. Drip System of Irrigation
Drip Irrigation
The most commonly used method of irrigation these days is the drip method. They lay the pipes in rows near the crops or plants. These plastic pipes have holes in them. Water seeps from these holes drop by drop, hence the name drip irrigation. This is an extremely efficient method of irrigation as it reduces water wastage.
2. Sprinkler System
Sprinkler Irrigation
This system mimics the phenomenon of rain. Water is carried by pipes to central locations on the farm. Sprinklers placed here distribute the water across the fields. This is the most efficient method to irrigate the uneven land. Sprinkler system also provides the best coverage regardless of the size of the farm.
