The most important variable characteristics of estuary water are the concentration of dissolved oxygen, salinity and sediment load. There is extreme spatial variability in salinity, with a range of near-zero at the tidal limit of tributary rivers to 3.4% at the estuary mouth. At any one point, the salinity will vary considerably over time and ...
Other types of estuaries also exist and have similar characteristics as traditional brackish estuaries. The Great Lakes are a prime example. There, river water mixes with lake water and creates freshwater estuaries. [16] Estuaries are extremely productive ecosystems that many humans and animal species rely on for various activities. [17]

St. Lawrence River Estuary stretches from west to east for 655 km, from the outlet of Lake Saint Pierre to Pointe-des-Monts, [1] where it becomes the Gulf of St. Lawrence, in Quebec, Canada. The estuary is divided into 3 parts: the fluvial estuary , the middle estuary and the maritime estuary .
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.

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 provide habitats for a large number of organisms and support very high productivity. Estuaries provide habitats for salmon and sea trout nurseries, [43] as well as migratory bird populations. [44] Two of the main characteristics of estuarine life are the variability in salinity and sedimentation.
The Brazos River Estuary is the second of three minor estuaries located on the upper-mid Texas coast in Brazoria County between Matagorda Bay and Galveston Bay. It is a riverine estuary system consisting only of the lower reaches of the Brazos River, with no associated bay. [44]
