Canal liners themselves do not directly prevent sediment buildup, but they help by providing a smooth surface that reduces areas where sediment can accumulate. Over time, sediment can still settle on the liner, especially in canals with slow water flow or high sediment loads. Regular cleaning and maintenance are necessary to address this.
Cleaning and maintenance often involve mechanical dredging or flushing to remove accumulated sediment. The durability and impermeability of the liner protect it during these cleaning processes, ensuring the canal remains functional without compromising the liner's integrity
