　　Several materials are commonly used for channel lining, depending on factors such as cost, availability, soil conditions, and the intended purpose of the canal. Here are some of the materials used in canal lining:

　　Concrete: Concrete lining is a popular choice due to its durability and impermeability.

　　Clay: Clay is an inexpensive material that can be used to line canals. It is compacted and smoothed to form a seal against water seepage.

　　Geomembranes: Geomembranes are synthetic materials made of high-density polyethylene (HDPE), polyvinyl chloride (PVC), or other similar materials.

　　Bentonite-based liners: Bentonite is a clay-based material that swells when hydrated, forming a low-permeability gel-like barrier.

　　Asphalt: Asphalt lining involves the application of a layer of asphalt on the canal surface.

　　Plastic liners: Plastic liners, such as high-density polyethylene (HDPE) or polyvinyl chloride (PVC) sheets, are used as impermeable barriers.
