Model of Estuary. The residence time of water is a key variable determining the health of an estuary, particularly from human-induced stresses.Rapid flushing ensures that there is insufficient time for sediment accumulation or dissolved oxygen depletion in the estuary; thus a well flushed estuary is intrinsically more robust than a poorly flushed estuary.

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. [1] Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone .
Within the delta region, the river split into multiple braided channels and formed a complex estuary and terrestrial ecosystems. The use of water upstream and the accompanying reduction of freshwater flow has resulted in the loss of most of the wetlands of the area, as well as drastic changes to the aquatic ecosystems - an ecosystem collapse.
The East River is a saltwater tidal estuary or strait in New York City. The waterway, which is not a river despite its name, connects Upper New York Bay on its south end to Long Island Sound on its north end. It separates Long Island, with the boroughs of Brooklyn and Queens, from Manhattan Island, and from the Bronx on the North American ...
Today, the St. Lawrence River begins at the outflow of Lake Ontario and flows adjacent to Cape Vincent, Gananoque, Clayton, Alexandria Bay, Brockville, Morristown, Ogdensburg, Massena, Cornwall, Montreal, Trois-Rivières, and Quebec City before draining into the Gulf of St. Lawrence, often given as the largest estuary in the world.

Estuary freshwater inflow is the freshwater that flows into an estuary. Other types of environmental flows include instream flow , the freshwater water flowing in rivers or streams, and estuary outflow , the outflow from an estuary to the ocean .
Little Squalicum Creek again empties into Bellingham Bay, with a new estuary designed to provide habitat for young salmon and other fish.. It’s part of a $5.7 million project that began in ...
Mobile Bay is the fourth-largest estuary in the United States with a discharge of 62,000 cubic feet (1,800 m 3) of water per second. [1] Annually, and often several times during the summer months, the fish and crustaceans will swarm the shallow coastline and shore of the bay.
