Tidal marsh

A tidal marsh is a type of marsh that is found along coasts and estuaries of which the flooding characteristics are determined by the tidal movement of the adjacent estuary, sea or ocean ^[1]. According to the salinity of the flooding water, freshwater, brackish and saline tidal marshes are distinguished. Respectively, they may be classified into coastal marshes and estuarine marshes.

They are also commonly zoned into lower marshes (also called intertidal marshes) and upper or high marshes, based on their elevation with respect to the sea level.^[1]^[2]

In addition they may also be classified into back-barrier marshes, estuarine brackish marshes and tidal freshwater marshes, according to the degree of the influence of the sea level. ^[2]
