When the waves move landward, sand and mud accumulate parallel to the coastline and form an offshore bar that is higher than sea level. The bar eventually separates the water from the open sea, forming a semi-enclosed or enclosed lagoon on the landward side. Based on the materials that form the embankment, lagoons can be categorised into coastal lagoons and coral lagoons. Coastal lagoons are widely distributed around the world, accounting for 13% of the total coastline, and are mainly in areas with small tidal ranges, low wave energy, and adequate sediments to form bars to protect the coastline. Coral lagoons are mainly located in the extensive seas in the tropics, which are suitable for coral to grow, mainly in regions below 25° latitude. The West Lake in Hangzhou...
