 The Itsukushima Shrine is a historic site located in Hiroshima Bay, Japan. Due to its unique location, the shrine has been subjected to frequent flooding from strong winds and storms. A team of researchers used a numerical ocean circulation model to investigate the cause of this phenomenon. They found that the typhoon's winds had created a disturbance in the density stratification of the water, which resulted in the formation of internal waves. These waves then traveled southwards before returning northwards, resulting in higher than normal levels of water in the northern bay. The researchers concluded that their findings could be applied to other similar bodies of water, such as semi-enclosed bays, to help predict and mitigate future floods.
