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.
The result is often a very large estuary at the mouth of a relatively insignificant river (or else sediments would quickly fill the ria). The Kingsbridge Estuary in Devon, England, is an extreme example of a ria forming an estuary disproportionate to the size of its river; no significant river flows into it at all, only a number of small ...
Estuaries of Australia are features of the Australian coastline. They are linked to tides, river mouths and coastal features and conditions. They are linked to tides, river mouths and coastal features and conditions.
When there is a series of estuaries involved, a large exposure time (larger than that of the individual estuaries), will occur if the tidal outflow from one estuary re-enters a different estuary during the flood tide. Along a rugged coastline with headlands, however, mixing of estuary and oceanic waters can be intense. When estuarine water ...
Estuaries are extremely productive ecosystems that many humans and animal species rely on for various activities. [17] This can be seen as, of the 32 largest cities in the world, 22 are located on estuaries as they provide many environmental and economic benefits such as crucial habitat for many species, and being economic hubs for many coastal ...
Its mean depth is also the greatest in the world (749 metres (2,457 ft)). It is also the world's largest freshwater lake by volume (23,600 cubic kilometres (5,700 cu mi), but much smaller than the Caspian Sea at 78,200 cubic kilometres (18,800 cu mi)), and the second longest (about 630 kilometres (390 mi) from tip to tip).

Areas where mangroves occur include estuaries and marine shorelines. [19] The intertidal existence to which these trees are adapted represents the major limitation to the number of species able to thrive in their habitat. High tide brings in salt water, and when the tide recedes, solar evaporation of the seawater in the soil leads to further ...
