Hydrology of Coastal Wetlands

Hydrology – the frequency, duration, and timing of inundation and/or soil saturation - is the lifeblood of wetlands. The presence of water strongly influences the physical and chemical environment, biota, productivity, and connectivity between wetlands and waterbodies and among habitats within wetland complexes. Wetlands occurring along the shorelines of the world’s oceans, estuaries, and tidal rivers are called coastal wetlands or tidal wetlands. Their hydrology is largely influenced by the tides and factors that affect the tides such as the position of the moon and sun relative to the Earth’s surface, local weather conditions, and river discharge. Consequently, site wetness is dynamic, changing daily. For example, some portions of coastal wetlands are inundated nearly every day by the tides, while other portions are infrequently flooded.
