Water transportation refers to the movement of water over large distances, and it can be divided into three categories: aqueducts, container shipment, and towing. Aqueducts include pipelines, canals, tunnels, and bridges, while container shipment includes transport by tank truck, tank car, and tank ship. Towing involves using a tugboat to pull an iceberg or a large water bag along behind it. Water transportation is also very common in rivers and oceans, and it is ideal for transporting heavy, bulk freight such as grain, minerals, metals, ores, steel coils, and heavy machinery.

There are various types of water transport, including boats, barges, speedcrafts, steamers, trawlers, dinghies, and more. Water transport can be classified based on the routes or types of waterways catering to the traffic, such as riverine transportation, which is responsible for transport in a river. Water transport is the most cost-effective method of moving large, perishable, and heavy products across long distances, and it has a very low operating cost. However, it is also a highly inefficient kind of transport, and it takes a lengthy time to travel or transport things.
