. Irrigation canal carries water to the agricultural field. To make the regulation of supply in the canal easy To control silt entry into the canal To shut out river floods. For large canals head regulators are flumed to facilitate the measurement of discharge.

Here we detail about the fourteen important design principles for head regulators. Regulators are normally aligned at 90 to the weir. These are used for diversion of flow.

Functions of Diversion Headworks. Some times from economic considerations the canal section is flumed at the regulator site to reduce width of the. Canal fall- necessity and location- types of falls- Cross regulator and distributory head regulator- their functions Silt control devices Canal escapes- types of escapes.

I Crest level of the cross regulator should generally be kept in level with the upstream bed level of the canal. Con stru ction. Due to relatively clear water for design flood retrogression is assumed 03 to 05 m ds TEL us TEL - head loss afflux retrogression 110 Divide Wall parallel to canal head regulator separates main weir bays and floor from undersluice bays and floor.

Up to 24 cash back Introduction to Canal Head Regulation. The components of head regulator depends upon the size of canal and location of head regulator. Carrier canal along with irrigation carries water for other canals.

They also help to maintain the water. The canal head regulator is usually gated to control the mount of flow into the canal Lay Out of Headregulator Angle between stream channel and the diversion channel has considerable effect on the. It regulates the intake of water into the canal.

It raises the water level in the river so that the command area can be increased. It reduces fluctuations in the level of supply in the river. Read this article to learn about the twelve design principles for cross regulator and distributary head regulators.

Silt reduces carriage capacity of flow. Regulators are normally aligned at 90 to the weir. MODULE- 4 Canal regulation works Prepared by Bibhabasu Mohanty Dept.

This is the work provided at the head of a branch canal or a distributary and serves the purpose of controlling and regulating the flow into the offtake as well as metering of the flow. The design of head regulator should serve the following objects. Silt reduces carriage capacity of flow.

The various regulation works may be classified as follows. It consists of one or more gated research openings with barrels running through the bank. Ii The crest level and the waterway required by the head regulator are interrelated because the.

The arrangement is more or less similar to that of a canal head regulator with a raised crest upstream and downstream floors and cutoffs. Reservoir may consist of nu ber of spans separated by piers and operated by gates. The openings are provided with adjustable gates at the base of the weir and barrage is known as.

A Scouring sluices b Under sluices c Both a and b d Silt excluder e None of these. These are used for diversion of flow. Upto 10 are considered preferable for smooth entry into canal.

I The crest level of the head regulator should be fixed higher than the crest of the under-sluices of the barrage with or without the silt excluder by 125 to 2 m to avoid silt entry into the canal. The hydraulic design of canal head regulator horizontal and sloping apron consists of the following. 1982 Criteria for design of lined a canals and guidelines for selec- tion type of lining b 3 LOCATION AND LAYOUT 31 Location The location of canal head regulator is inter-.

The silt of the under-sluice pocket is kept at or slightly above the deepest river bed and about 09. Canal regulation works. These structures are necessary for the efficient working and safety of an irrigation channel.

These include the cross regulator and the distributary head regulator structures for controlling the flow through a parent canal and its off-taking distributary as shown in Figure 123. Feeder canal it feeds 2 or more canals. 1 Canal Fall 2 Head Regulator 3 Cross.
