Waves - A Great Example of a Tidal Bore

Some fascinating footage here of a tidal bore which swept up the Qiantang River in the eastern Zhejiang Province of China in August 2013. No-one was killed but 30 people were injured as crowds gathered to watch the tidal bore.

A tidal bore occurs along a coast where a river empties into an ocean or sea. A tidal bore is a strong tide that pushes up the river, against the current. A tidal bore is a true tidal wave.
