Components of a canal lining:

Concrete Lining: This durable and strong material is used in high-flow canals.

Clay Lining: As long as it's economical, effective, and well-compacted.

Geomembranes: Flexible synthetic sheets designed to halt leaks.

Shotcrete: A spray-poured concrete lining that is seamless.

Riprap: Large stones to stop erosion are called riprap.

Gravel lining: controls erosion and reduces seepage.

Synthetic Liners: plastic or rubber that resists chemicals and UV rays.

Geotextiles are textile materials that stabilize and stop soil erosion.

These materials are chosen taking into account factors like cost, durability, and specific canal requirements.
