Purpose of Cross Regulator in a Canal:
A cross regulator is a structure built across the canal to regulate the flow of water. Its purpose is to ensure adequate water supply to the off-taking channel and maintain the required water level in the canal. The following are the detailed explanations of the purpose of cross regulator in a canal:
Regulate Water Supply in the Off-taking Channel:
The main function of the cross regulator is to regulate the water supply in the off-taking channel. It controls the flow of water from the main canal into the off-taking channel. This is important because different off-taking channels require different water supplies depending on their location and the crops grown in that area. The cross regulator helps in maintaining a constant water supply to the off-taking channel.
Regulate Water Supply in the Main Channel:
The cross regulator also regulates the water supply in the main canal. It ensures that the water flow is consistent, and no excess water is wasted. When the water levels in the canal rise, the cross regulator diverts the excess water to the off-taking channel, which prevents flooding in the canal.
Head up Water for Adequate Supply into the Off-taking Channel:
The cross regulator also helps in heading up water for adequate supply into the off-taking channel. The structure of the cross regulator is designed in such a way that it can raise the water level in the canal, which increases the water supply into the off-taking channel. This is particularly crucial during the dry season when water supply is low.
Regulate Excessive Flood Water:
The cross regulator also helps in regulating excessive flood water. During the monsoon season, the water level in the canal rises, and there is a risk of flooding. The cross regulator diverts the excess water to the off-taking channel, which prevents flooding in the canal and nearby areas.
Conclusion:
In conclusion, the cross regulator is an essential structure in a canal system. Its primary purpose is to regulate the flow of water, maintain water levels, and ensure adequate water supply to the off-taking channel. By regulating the water supply in the canal system, the cross regulator helps in preventing flooding, conserving water, and ensuring that farmers get adequate water supply for their crops.
