The texture of a canal liner can significantly affect its performance. Smooth liners, such as certain geomembranes, reduce friction and promote efficient water flow, which is particularly beneficial in irrigation canals where minimizing resistance is important.
Textured liners, on the other hand, provide better grip and stability on steep slopes or uneven surfaces, reducing the risk of slippage during installation or under high water pressure. In some cases, textured surfaces help anchor the liner to the soil, preventing movement and enhancing durability.
