tidal river
Ocean-influenced stream
A tidal river is a river whose water level rises and falls with ocean tides, typically in its lower reaches near the sea.
The tidal influence can extend many miles inland, creating zones where fresh river water mixes with saltwater: The tidal river flooded the docks twice daily.
These stretches support distinctive ecosystems adapted to fluctuating salinity and water levels.
