Detailed explanation-1: -Brackish water is less salty than seawater, but it is more salty than fresh water. Brackish water can be found where fresh water mixes with seawater, for example in estuaries and where rivers flow into the ocean.

Detailed explanation-2: -Salt marshes are located downstream from brackish marshes. Low salt marshes have higher water salinity values than brackish tidal marsh communities, are more heavily influenced by tides, and are typically dominated by the tall form of saltwater cordgrass (Spartina alterniflora).

Detailed explanation-3: -Water with a TDS concentration less than 3, 000 mg/L can be considered fresh water. Water from 3, 000-10, 000 Mg/L TDS will be considered brackish Water in excess of 10, 000 Mg/L will be considered saline. Ground water with salinity greater than seawater (about 35, 000 mg/L) is typically referred to as brine.

Detailed explanation-4: -Hypersaline environments within salt marshes occur in “salt pans” where tidal water collects and evaporates. High marshes flood infrequently, mid marshes flood usually at higher tides and are usually brackish waters, while low marshes are inundated with saltwater daily.
