Detailed explanation-1: -An estuary is an area where a freshwater river or stream meets the ocean. In estuaries, the salty ocean mixes with a freshwater river, resulting in brackish water. Brackish water is somewhat salty, but not as salty as the ocean. An estuary may also be called a bay, lagoon, sound, or slough.
Detailed explanation-2: -An estuary is a partially enclosed, coastal water body where freshwater from rivers and streams mixes with salt water from the ocean.
Detailed explanation-3: -The mixture of seawater and fresh water in estuaries is called brackish water and its salinity can range from 0.5 to 35 ppt.
Detailed explanation-4: -The term estuary is derived from the Latin words aestus (“the tide”) and aestuo (“boil”), indicating the effect generated when tidal flow and river flow meet. Estuaries are places where rivers meet the sea and may be defined as areas where salt water is measurably diluted with fresh water.
Detailed explanation-5: -An estuary is an enclosed water region where freshwater from the lakes and streams mixes with the saltwater from the ocean. An estuary is a transition zone from the river to the ocean or maritime ecosystem.
