Page "Harbor" Paragraph 6

A natural harbor is a landform where a part of a body of water is protected and deep enough to furnish anchorage.

Many such harbors are rias.

Natural harbors have long been of great strategic naval and economic importance, and many great cities of the world are located on them.

Having a protected harbor reduces or eliminates the need for breakwaters as it will result in calmer waves inside the harbor.

Some examples are Kingston Harbour in Jamaica, Subic, Zambales in the Philippines ; Sydney Harbour in Australia ; Pearl Harbor in Hawaii ; San Francisco Bay in California ; Visakhapatnam Harbour in Andhra Pradesh, India ; and Halifax Harbour in Nova Scotia, Canada.
