What is another word for tidal bore?
Pronunciation: [tˈa͡ɪdə͡l bˈɔː] (IPA) 
A tidal bore is a natural occurrence that happens in some river estuaries and bays when an incoming tide collides with an outflowing river current. It creates a powerful wave that travels upstream. Another term for a tidal bore is a tidal wave, but it can be confusing as this term is more commonly associated with tsunamis. Other synonyms for tidal bore include eagre, aegir, mascaret, or bore wave. The term bore itself comes from the Old Norse word "barr," which means wave or swell. In French, the term "mascaret" means "a wave that heads up the estuary," while the term "eagre" is derived from the Old English word meaning "fierce".
