Why is the fishing port of Yinggehai in Ledong too shallow to stop big ships?

Sediment accumulation. The sea area where Ledong Yinggehai Fishing Port is located may be a shallow sea area. The seabed topography is relatively flat or there are many shoals, resulting in shallow water depth. There are a lot of sediments around the harbor, which will gradually accumulate at the bottom of the water, resulting in shallow water depth. Therefore, its water depth is too shallow to accommodate large ships and it is impossible to dock.
