Canal vs. Channel: What's the Difference?

Edited by Janet White || By Harlon Moss || Published on December 9, 2023
A canal is a man-made waterway constructed for navigation, irrigation, or water transport, while a channel is a natural or artificial passage for water.

Key Differences

A canal is an artificial waterway, often constructed to connect different bodies of water for navigation, irrigation, or water transport. Channels, on the other hand, can be natural or artificial passages, primarily serving as pathways for water to flow, like river channels or straits.
Canals are engineered with locks and gates to manage water levels and facilitate transport. Channels, especially natural ones, follow the natural topography and are shaped by environmental factors like erosion.
Canals play a crucial role in human-made transportation networks, often altering geographical landscapes for economic purposes. However, channels, particularly natural ones, are integral to ecosystems, directing water flow in rivers, seas, and oceans.
The maintenance of canals often involves regular dredging and repair to keep them navigable. Channels, especially natural ones, require conservation efforts to preserve their ecological balance.
Famous canals include the Panama Canal and the Suez Canal, known for their significant roles in global maritime trade. Well-known channels include the English Channel and river channels like the Mississippi River channel.
