An estuary is a dynamic ecosystem having a connection to the open sea through which the sea water enters with the rhythm of the tides. The effects of tides on estuaries can show nonlinear effects on the movement of water which can have important impacts on
Estuaries occur where there is a noticeable change in salinity between saltwater and freshwater sources. This is typically found where rivers meet the ocean or sea. The wildlife found within estuaries is unique as the water in these areas is brackish - a mix of freshwater flowing to the ocean and salty seawater. [16]
False Bay, Lake St Lucia This is a list of estuaries in South Africa. The list is in order from East (border with Mozambique) to the West (border with Namibia). The South African coastline stretches for some 3000 km from Kosi Bay near the Mozambique border in the east to the Gariep (Orange) River at the Namibian border in the west. Some 300 river outlets intersect this coastline and these ...
More than half of England’s estuaries are at risk of seeing habitats squeezed between rising seas and man-made barriers on land. Important estuary habitats being ‘squeezed out’ by climate ...
Estuaries occur where there is a noticeable change in salinity between saltwater and freshwater sources. This is typically found where rivers meet the ocean or sea. The wildlife found within estuaries is unique as the water in these areas is brackish - a mix of freshwater flowing to the ocean and salty seawater. [20]
The inflow of both seawater and freshwater provide high levels of nutrients in both the water column and sediment, making estuaries among the most productive natural habitats in the world. [41] Most estuaries were formed by the flooding of river-eroded or glacially scoured valleys when sea level began to rise about 10,000-12,000 years ago. [42]
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.

Little more than one percent of this reserve has been subject to human development. The area is one of the least disturbed estuaries in the densely populated urban corridor of the northeastern United States. On October 20, 1997, the Jacques Cousteau National Estuarine Research Reserve (JC NERR) was dedicated in honor of Jacques-Yves Cousteau. [2]
