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 ...
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] Other types of estuaries also exist and have similar characteristics as traditional brackish estuaries. The Great Lakes are a prime ...
This term has been widely used to refer to beaches inside estuaries and bays where locally-generated wind waves are the main source of hydrodynamic energy [5] [32] [25] [7] however, the term can also be applied to beaches outside estuaries and bays, with different characteristics. Sheltered beaches.
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.

The seven major estuaries are all separated from the Gulf of Mexico by the Texas barrier islands and various peninsulas on the mainland, making them into sheltered bays, [1] whereas several of the minor estuaries have no barrier islands or embayments but are riverine estuaries that empty directly into the Gulf.

There, the two bodies of water that mix off the coast of Tadoussac give the Maritime Estuary characteristics that distinguish it from other reaches of the St. Lawrence: nutrient-rich surface waters throughout the summer and upwellings of deep, cold water that favour the formation of Euphausiids. -Krill.
The littoral zone, also called litoral or nearshore, is the part of a sea, lake, or river that is close to the shore. [1] In coastal ecology, the littoral zone includes the intertidal zone extending from the high water mark (which is rarely inundated), to coastal areas that are permanently submerged — known as the foreshore — and the terms are often used interchangeably.
