tidal rivers
Sea-influenced streams
Tidal rivers are rivers whose water levels rise and fall with ocean tides.
The tidal influence can extend far inland—the Hudson River feels tides over 150 miles from the sea.
The water in tidal sections may be fresh, brackish, or salt depending on distance from the ocean and seasonal flow.
These stretches create distinctive ecosystems where freshwater and marine life overlap.
