Analysis of Drift Ice Influence on Navigation Mark in Yalujiang River Estuary

The drift ice is very seriously that impact the navigation safety and port operation in Yalujiang estuary area. By collecting the datum of hydrometeorology, geomorphology and ice regime in Yalujiang estuary for many years, systematically analyzed the characteristic of drift ice influenced by the ocean current, wind and geomorphology. The destruction mechanism of navigation mark by drift ice are studied, and the countermeasures and protection measures for navigation mark are also proposed.
