Harbor in the context of "Sydney Harbour"

An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world.

Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as bays, harbors, lagoons, inlets, or sounds, although some of these water bodies do not strictly meet the above definition of an estuary and could be fully saline.

Triport or Treport is a cape and historic harbor on the Adriatic Sea northwest of Vlorë, Albania. It is located in Vlorë municipality, and constitutes the northern limit of the Bay of Vlorë. Located 5 km northwest of the city, the harbor of Triport is the Fishing Port of Vlorë. It is one of the most important fishing ports of Albania, featuring the country's second largest fishing fleet.

A body of water or waterbody is any significant accumulation of water on the surface of Earth or another planet. The term most often refers to oceans, seas, and lakes, but it includes smaller pools of water such as ponds, wetlands, or more rarely, puddles. A body of water does not have to be still or contained; rivers, streams, canals, and other geographical features where water moves from one place to another are also considered bodies of water.

Most are naturally occurring and massive geographical features, but some are artificial. There are types that can be either. For example, most reservoirs are created by engineering dams, but some natural lakes are used as reservoirs. Similarly, most harbors are naturally occurring bays, but some harbors have been created through construction.

The Narrows is the tidal strait separating the boroughs of Staten Island and Brooklyn in New York City. It connects the Upper New York Bay and Lower New York Bay (of larger New York Bay) and forms the principal channel by which the Hudson River flowing south from upstate New York and the New England regions, empties into the Atlantic Ocean. It has long been considered to be the maritime gateway to New York City and the Northeastern United States on the East Coast of North America, and historically has been one of the most important entrances into the seaport harbors of the Port of New York and New Jersey.

Oricum (Ancient Greek: Ὤρικον, Ὤρικος or Ὠρικός; Latin: Oricum or Oricus; Albanian: Oriku or Orikum) was a harbor on the Illyrian coast that developed in an Ancient Greek polis at the south end of the Bay of Vlorë on the southern Adriatic coast. It was located at the foot of the Akrokeraunian Mountains, the natural border between ancient Epirus and Illyria. Oricum later became an important Roman city between the provinces of Epirus Vetus and Epirus Nova in Macedonia. It is now an archaeological park of Albania, near modern Orikum, Vlorë County. Oricum holds such a strategic geographical position that the area has been in continuous usage as a naval base from antiquity to the present-days.

It appears that the site of Oricum was uninhabited before the 6th century BC. In the early period contacts between the Greeks and the local Illyrians were evidently absent in the hinterland of the site. Early Greek sources describe Orikos as a harbor (Greek: λιμήν, limen). Findings from the proto-urban period in Orikos provide evidence of extensive contacts primarily with the Greek world. Like other ports of southern Illyria, the site of Orikos was a place of exchange of products and a meeting point between the outside world and the Illyrians located in the hinterland. In the Classical period Orikos was likely part of the peraia of Korkyra.
