Lining a canal offers several benefits, primarily by improving water retention and reducing seepage. A properly installed liner prevents water from infiltrating the surrounding soil, conserving water, and increasing the efficiency of irrigation or drainage systems. This is especially valuable in areas with water scarcity.
Canal liners also protect against soil erosion by providing a stable, impermeable surface that reduces the risk of scouring and sediment loss. Lining a canal can also help control vegetation and weed growth, reducing the need for chemical treatments and manual labor. Furthermore, liners improve water flow by creating a smooth surface, which can enhance the speed and efficiency of water transportation.
