MISCELLANEOUS CANAL STRUCTURES

Canal falls, head regulators, canal escapes, metering flumes, canal outlets and modules are canal structures. The best alignment of off-taking channel is when it makes zero angle with the parent channel initially and then separates out in transition. * The main function of a head regulator is 1. To control the supplies entering the off-take channel 2. To control silt entry into off-take channel 3. To serve as a meter for measuring discharge * The main functions of a cross regulator are: 1. Control canal irrigation system. 2. When the water level in the main canal is low, it helps in heading up water. 3. It helps in absorbing fluctuations in various sections of the canal system. 4. It is often combined with a road bridge and a fall, if required. Canal Escapes * A canal escape is a side channel constructed to remove surplus water from an irrigation channel. * The importance of such an escape is realised more, in case, a breach occurs in a channel. * Weir type and sluice type (regulator t...
