CHANNEL LINING

Definition: The process of creating a hard, impermeable layer on the bed and banks of artificial waterways, such as drainage ditches, canals, or irrigation channels.

Core Function: To prevent soil erosion caused by high-velocity water flow and to eliminate water loss through soil seepage.

How it Works: It transforms a raw earth channel into a smooth, rigid conduit, which reduces hydraulic friction, accelerates water flow, and maximizes discharge capacity.
