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 learn more about the mascaret’s history.
The Seine River in France is probably the best example of human engineering eliminating the costly and lethal problems caused by bores. For centuries, people and businesses living and working along the Seine River were held hostage to an unpredictable bore, called the mascaret. The mascaret was responsible for hundreds, if not thousands, of ships being sunk by the surprise bore. Throughout the 18th and 19th century, construction of dams, canals, irrigations systems and dredging efforts killed off the mascaret.
