Description

Canals are human-made channels for water. There are two types of canal:

  • 1. Aqueduct (or water conveyance) canals that are used for the conveyance and delivery of fresh water, for human consumption, agriculture, etc.
  • 2. Waterway canals that are navigable transportation canals used for carrying ships and boats loaded with goods and people, often connected to existing lakes, rivers, or oceans.

The word "canal" is also used for a city-canal in cities such as Venice (canal grande), Amsterdam (gracht) or Bangkok.
