old irrigation methods of Himachal pradesh. ( max - 3 paragraph)
Answers
Answer:
Kuhls are a traditional irrigation system in Himachal Pradesh- surface channels diverting water from natural flowing streams (khuds). A typical community kuhl services six to 30 farmers, irrigating an area of about 20 ha. The system consists of a temporary headwall (constructed usually with river boulders) across a khud (ravine) for storage and diversion of the flow through a canal to the fields. By modern standards, building kuhls was simple, with boulders and labour forming the major input. The kuhl was provided with moghas (kuchcha outlets) to draw out water and irrigate nearby terraced fields. The water would flow from field to field and surplus water, if and, would drain back to the khud.
The kuhls were constructed and maintained by the village community. At the beginning of the irrigation season, the kohli (the water tender) would organise the irrigators to construct the headwall, repair the kuhl and make the system operational. The kohli played the role of a local engineer. Any person refusing to participate in construction and repair activities without valid reason, would be denied water for that season. Since denial of water was a religious punishment, it ensured community participation and solidarity. A person was also free to participate by providing a substitute for his labour. The kohli also distributed and managed the water.
