Definition
A tidal flat salinity gradient is the systematic or progressive across-tidal-flat change in salinity in groundwater (as pore water) and pellicular water due to the interacting effects of inundation, evaporation, transpiration, sediment types, and freshwater seepage.
Tidal flat salinity
During low tide, when tidal flats are exposed, water under or within a tidal flat is subject to evaporation and transpiration, resulting in its salinization, or to dilution by freshwater seepage. During a low tide, there are two sub-environments where tidal flat water resides (Figure 1):
