(Redirected from Tidal bore)


  1. A tidal wave that propagates as a solitary wave with a steep leading edge up certain rivers.

    Bore formation is favored in wedge-shaped shoaling estuaries at times of spring tides. Other local names include eagre (River Trent, England), pororoca (Amazon, Brazil), and mascaret (Seine, France).
