  Estuary - LoveToKnow 1911
Structurally the estuary may represent the long-continued action of river erosion and tidal erosion confined to a narrow channel, most effective where most concentrated, or an estuary may be the drowned portion of the lower part of a river-valley.
In a map of Britain showing sea-depths it will be observed that under the Severn estuary the sea deepens in a number of steps descending by concentric V's that become blunter towards deep water until the last is a mere indentation pointing towards the long narrow termination of the present estuary.
In this and in similar cases the progress of the estuary is indicated upon what is now the continental shelf.

 Estuary - Wikipedia, the free encyclopedia
An estuary is a mouth of a river with a triangle form, semi-enclosed coastal body of water which has a free connection with the open sea and within which seawater mixes with fresh water.
An estuary is typically the tidal mouth of a river, and estuaries are often characterised by sedimentation of silt carried in from terrestrial runoff.
Estuaries are more likely to occur on submerged coasts, where the sea level has risen in relation to the land, as this process floods valleys to form rias and fjords.

 EPA > National Estuary Program > About Estuaries
An estuary is a partially enclosed body of water along the coast where freshwater from rivers and streams meet and mix with salt water from the ocean.
Estuaries and the lands surrounding them are places of transition from land to sea, and although influenced by the tides, they are protected from the full force of ocean waves, winds, and storms by such landforms as barrier islands or peninsulas.
Estuaries are often the cultural centers of coastal communities, serving as the focal points for local commerce, recreation, celebrations, customs, and traditions (2).

Chesapeake Bay is one of the largest estuaries of this type in the United States and was formed during the melting of the Pleistocene ice sheets (see Pleistocene epoch).
The shape of an estuary affects the height of the tide; some estuaries (such as the Severn and the Bay of Fundy) are characterized by a wavelike tidal bore.
Human impact on estuaries includes reclamation of tidal land by filling; pollution from sewage, solid waste, industrial effluent, and hot water; increased sedimentation filling the estuary; and alteration of the salinity of estuarine waters by withdrawal or increased influx of freshwater.

An estuary is typically the mouth of a river, and estuaries are often characterised by sedimentation of silt from the river, which provides a unique habitat, for example, for wading birds.
Estuaries are more likely to occur on submerged coastlines, where the sea level has risen in relation to the land, as this process floods valleys to form rias, fjords etc, which can be classified as estuaries.

 The Hudson River Estuary - The Basics
An estuary is a semi-enclosed coastal body of water with a free connection to the open sea and within which sea water is diluted by fresh water.
Estuaries are geologically ephemeral and can rapidly disappear with a relatively small change in sea level via glaciations (drop of sea level) and deglaciations (rise of sea level).
Estuaries may originate from (1) the drowning of river valleys or fjords, (2) the formation of barrier beaches that enclose a shallow bay, or (3) tectonic activity (Levinton 1982).

The St. Louis Estuary serves as the primary nursery for the fish found in western Lake Superior, and is home to over 45 native fish species, including walleye, lake sturgeon, muskellunge, northern pike and smallmouth bass.
The combination of ecosystems within the St. Louis Estuary — estuarine wetland and aquatic habitats, baymouth bar complex, its importance to breeding and migratory birds, and its importance to native fish, — are very unusual in Lake Superior, the Upper Midwest, the Great Lakes, and around the world.
