Mascaret
Quick Summary
The mascaret is a tidal bore that occurs on the Seine River in France. A tidal bore is a wave phenomenon that happens when exceptionally high sea tides rush up rivers or estuaries, especially where the incoming tide is confined to a narrow channel. The mascaret forms on spring tides and can travel upstream as far as Rouen. It is characterized by a well-defined front of one or more waves, often breaking, followed by a main body that rises higher than the water level at its front. While historically significant, continued dredging of the Seine River has caused the mascaret to diminish.12
