DIVERSION HEADWORKS

Diversion headworks are built across a river to stop the water from flowing and raise the water level. The water is then sent to canals for irrigation and other uses. Over the canals, diversion headworks, which are also called canal headworks, are built. They help control the flow of water into the canals and keep silt and other sediments from getting in. It makes a small body of water called a pond.

Functions Of Diversion Headworks

• It controls the quantity of water diverting into the off-taking canal.
• The amount of mud diverted into the canal is regulated.
• It regulates the water levels in the river. It causes the river water to flow out of the river and into the off-taking canal.
• By raising the canal's outflow level, more land can be brought under the control of the proposed canal system.
• Due to fluctuation in the flow, the level of water in the river keeps fluctuating. These fluctuations in the river water level are lessened by diversion works.
• Although water storage isn't the main function of the diversion headwork, some water is still stored.This water can be used to make up for the lack of water in the river during dry weather flow.
