Subsidence Phenomena of the Coastal Structures into Offshore Sandy Seabed: A Review [ READ ]
A.B.M. Khan-Mozahedy
Coastal structures especially dikes and breakwaters may have balance on offshore sandy seabed. Foremost causes of lowering crest are consolidation of the foundation layers, wave-induced scouring and liquefaction. Many studies have been conducted to figure out the sinking phenomena of the coastal structures over the past decades. This article has reviewed the findings of observational, physical and real case studies to present comprehensive overview of the gradual sinking phenomena of maritime structures into sandy seabed. This study also reveals which sinking phenomena might have higher influence at what circumstances of marine hydrodynamics. Both consolidation and scour are quantifiable and may be incorporated during design of the crest level, while places susceptible to liquefaction are not suitable as construction site without ground improvement.
