Salt marsh during low tide, mean low tide, high tide and very high tide (spring tide). A coastal salt marsh in Perry, Florida, USA.. A salt marsh, saltmarsh or salting, also known as a coastal salt marsh or a tidal marsh, is a coastal ecosystem in the upper coastal intertidal zone between land and open saltwater or brackish water that is regularly flooded by the tides.
An inland salt marsh is a saltwater marsh located away from the coast. It is formed and maintained in areas when evapotranspiration exceeds precipitation and/or when sodium- and chloride-laden groundwater is released from natural brine aquifers. Its vegetation is dominated by halophytic plant communities. [1]
Saddle – Land connecting two high points; Salt marsh – Coastal ecosystem between land and open saltwater that is regularly flooded; Salt pan – Flat expanse of ground covered with salt and other minerals (salt flat) Sand boil, also known as sand volcano – Cone formed by the ejection of sand on a surface from a central point
Salt surface structures are extensions of salt tectonics that form at the Earth's surface when either diapirs or salt sheets pierce through the overlying strata. They can occur in any location where there are salt deposits, namely in cratonic basins, synrift basins, passive margins and collisional margins .
Salt marsh showing salt pannes and ponds, spartina alternifolia and invasive phragmites communis in foreground. Brackish marsh panne variants occur in brackish marshes (short graminoid variant), one of the native dominant species is spike grass (Distichlis spicata), some brackish marsh pannes are dominated by the narrow-leaved cattail (Typha angustifolia) an invasive exotic species.
The Bonneville Salt Flats, Utah. The Bonneville Salt Flats in Utah, where many land speed records have been set, are a well-known salt pan in the arid regions of the western United States. The Etosha pan, in the Etosha National Park in Namibia, is another prominent example of a salt pan. The Salar de Uyuni in Bolivia is
A halophyte is a salt-tolerant plant that grows in soil or waters of high salinity, coming into contact with saline water through its roots or by salt spray, such as in saline semi-deserts, mangrove swamps, marshes and sloughs, and seashores. The word derives from Ancient Greek ἅλας (halas) 'salt' and φυτόν (phyton) 'plant'.
Coastal reservoirs are fresh water storage reservoirs located on the sea coast near a river mouth to store the flood water of a river. [7] As the land-based reservoir construction is fraught with substantial land submergence, coastal reservoirs are preferred economically and technically since they do not use scarce land area. [8]
