river mouths
Where rivers end
River mouths are the places where rivers empty into larger bodies of water—oceans, seas, lakes, or other rivers.
The term emphasizes the opening or outlet: The city grew up around the river mouth.
River mouths often form deltas or estuaries where fresh and salt water mix.
