Research on Geological and Environmental Factors Related to the Sunk Ship Incident in the Laoyemiao Water Area,Poyang Lake-Yangtze River Channel
Poyang Lake is the largest freshwater lake in China.Laoyemiao waters,the only waterway of Poyang Lake connected to the Yangtze River,are navigable for ships of thousand-ton level.The Laoyemiao waters are known as the"Eastern Bermuda"as shipwrecks occur frequently in this area that results in life and property lost.Rare researches are applied in exploring the reasons,so multi-methods including geophysical prospecting,topography detection and hydrodynamic numerical simulation fill the void of evidence on study of shipwreck.Many karst caves in different scale are revealed.It is shallow except the channel in Laoyemiao waters.Torrents and vortexs are easy to show up in March and April.The result of geophysical prospecting and hydrodynamic numerical suggest that shipwreck in the Laoyemiao waters was mainly caused by the followings in addition to strong wind:underwater karst caves,torrents and vortexs.Besides,muddy water from five rivers makes the waters turbid as well as the underwater terrain and flow intricate.Among these causes,strong wind,torrents and vortexs dominate the shipwrecks and karst caves rarely result in shipwrecking.
