Tweet Photo by Adam Stanhope (astanhope on Flickr CC) A tidal bore is when waves of water rush through a narrow passage against the natural current of a body of water. Tidal bores are actually tidal waves, which are often mistakenly confused with tsunamis. Sometimes the phenomena of seawater being funneled through a river mouth can be quite spectacular, such as the annual tidal bore in China’s Qiantang River. From ITN News: Each year, just after the mid-Autumn festival, when the moon is at its fullest, a huge waves rolls along the wide mouth of the Qiantang near Hangzhou in China’s eastern Zhejiang province. Watch this dramatic video footage of a tidal bore at the mouth of the Qiantang River in China via ITN (its even got mannequins being knocked over by giant waves): For more on the story see the following article from New Zealand’s 3 News: Bizarre, beautiful, dangerous waves in China SUBSCRIBE TO NEWSLETTER Thank you, your sign-up request was successful!
