In our series of stories on tidal bores, we examine the geology, and details of some of the world’s most unusual bores including the Pororoca in Brazil, China’s Qiantang River bore, France’s mascaret, Malaysia’s benak, and surfing on the Alaskan Turnagain Arm bore. In this article, we’ll specifically look at one of the most famous bores in the world: the pororoca.
In Sri Aman, Malaysia, tidal bores occur twice daily, and at much smaller heights. Called the benak, these daily bores max out at approximately 5 feet (1.5 m) and have become a popular tourist attraction.
