A narrow waterway is a type of watercourse that is typically shallow and has a small width. Common examples of narrow waterways include creeks (5 letters), straits (6 letters), inlets (5 letters), rias (3 letters), and canals (5 letters). Creeks are usually small streams that flow into larger bodies of water, while straits are narrow channels of water that connect two larger bodies of water. Inlets are similar to straits, but they are usually smaller and more sheltered. Rias are coastal inlets that are formed by the partial submergence of a river valley. Canals are artificial waterways that are constructed for transportation or irrigation purposes.
