Types of Harbors. The locations for constructing harbors range from
open coastlines requiring artificial impoundments to natural bays, estuaries, and
navigable rivers that need a minimum of manmade structures for the necessary storm
protection. Within limits, harbors may be built wherever suitable water depth exists or
can be provided and maintained with dredging operations. The degree of artificial
works necessary to construct a viable harbor varies with the site's natural features.
Examples of various siting classifications are shown in Figure 2-1. The characteristics
of harbor location types are given in Table 2-1.
