Dredging involves removing materials from underwater to deepen channels or extract minerals, while concrete lining refers to applying a structural layer to support tunnels, reinforce riverbanks, or line canals to prevent erosion and manage water flow.
These methods are frequently combined in civil engineering projects—for instance, dredging clears silt and sediment to create space for a new channel, which is subsequently reinforced with concrete lining to ensure durability and stability.
