Canal liners play a significant role in reducing erosion by providing a stable, impermeable surface that prevents water from infiltrating the soil beneath the canal. Without a liner, water can seep through the canal bed, weakening the surrounding soil and leading to erosion over time. A properly installed liner helps maintain the structural integrity of the canal by preventing this seepage.
This reduces the risk of soil erosion along the canal’s edges and bottom. In areas with high water flow or steep gradients, liners protect against scouring, where fast-moving water can erode the soil. By controlling water movement and reducing soil disturbance, canal liners help preserve the canal's shape, minimize sediment loss, and ensure long-term functionality.
