The Definition of a Natural Harbor is a water body protected by natural or artificial obstacles. Harbors can provide secure anchorage and allow ship-to-shore transfers of cargo and passengers.
The word harbor is frequently used interchangeably with port, which is a man-made facility constructed to load and unload ships and drop off passengers and pick them up. Ports typically have one or more harbors. An instance of a port with two harbors is Alexandria Port in Egypt.
By definition, Harbors can be artificial or natural. An artificial harbor may have intentionally built breakwaters, sea walls, or jetties or may be built by dredging, which needs additional regular dredging to be maintained.
An instance of an artificial harbor is Long Beach Harbor, California, USA, which was too shallow a variety of salt marshes and tidal flats for contemporary merchant vessels before it was first dredged in the early 20th century.
In comparison, a if we want to give a definition of a natural harbor, we would say that it is an entity surrounded by prominence of soil on several sides. Examples of natural harbors include the Sri Lankan port of Sydney, Australia, and Trincomalee.
Ports vs terminals?
A terminal is a part of a port. A port generally describes the location where ships berth and conduct activity. Within a port there can be multiple terminals through which cargo passes from sea to land. A terminal instead refers to the specific part of a port dedicated to a certain type of activity, such as containers or bulks.
