Canal lining is the process of reducing seepage loss of irrigation water by adding an impermeable layer to the edges of the trench. Seepage can result in losses of 30 to 50 percent of irrigation water from canals, so adding lining can make irrigation systems more efficient.
What are the advantages of lining?
Advantages of lining
- Reduction in seepage losses: The seepage losses are substantially reduced by providing lining. ...
- Reduction in water logging: Seepage through the unlined canal is the main source of waterlogging. ...
- Higher velocities can be permitted: The lining offers higher velocity of flowing water in the canal.
What are the advantages of lined canals?
Canal Linings are provided in canals to resist the flow of water through its bed and sides. These can be constructed using different materials such as compacted earth, cement, concrete, plastics, boulders, bricks etc. The main advantage of canal lining is to protect the water from seepage loss.
