What is cement concrete lining of canal?

Cement concrete lining of a canal involves applying a layer of concrete to the inner surface of a canal to enhance its durability and reduce water seepage. This lining helps improve the flow of water, minimizes erosion, and prevents the growth of vegetation that can obstruct water movement. Additionally, it enhances the structural integrity of the canal, making it more resilient to environmental factors. Overall, cement concrete lining is an effective method for maintaining efficient water management in irrigation and drainage systems.
