Automated Flow Regulation for Canal

Published on 01 Apr 2021. Written by Reddy Shekar

The sluice gates are used to control water flow in canals. Gates are raised or lowered manually and then lift in position to achieve a target flow rate for the desired time period.

This system is based on labor-intensive and more time-consuming process. To avoid these problems researchers developed an automated flow regulation system to control water flow in canals. The automated flow regulation system works based on the flow rate in the canal.

The old conventional techniques and methods in the irrigation system are the biggest stakes for not achieving the high efficient results. There is a great need for advanced technologies like automated flow regulation system to obtain the desired outcomes within a short time. In this system, an appropriate control scheme is developed to automate the gate system for discharging the water from the canal.

The automated gate system is developed using automatic level control gates (Robogates) and ultrasonic water level sensors. A typical automated flow regulation system consists of 4 robo-gates installed in the canal at the downstream side and 9 sensors to monitor the water level. The sensors are installed at the downstream side, the upstream side and head tank for water level monitoring. The robo-gates are adjusted such that to supply a certain amount of water in particular areas.

How it works:

1. The automated flow regulation system independently monitors and react to changing water flows to maintain a consistent upstream level.
2. The automatic level compensates for changes in level automatically, resulting in more consistent water delivery.
3. Whenever the flow varies on the upstream side the gate adjusts its opening immediately.
4. Then, automatically gates allow the exact discharge required to keep the upstream water level constant.
5. In case of large flow, the gate opens wide enough to discharge the water.
6. For a low flow, the gate remains almost close.
7. When equilibrium is restored, the gate will remain motionless.

Benefits:

1. Cost-effective.
2. Requires less maintenance.
3. Control the levels in water delivery.
4. Provide a predictable and stable regulation system.
5. Provide precise water levels in distribution canals.
6. Eliminate frequent manual adjustment to weirs and gates.
7. No labour intensive is required.
8. Prevent water waste from overflow.

Conclusion:

Automated flow regulation is a useful system to enable precise water delivery. It also the best choice to reduce the overall cost of the irrigation project.
