  • In the present study, coastal dune deposits are analyzed to derive the information on historical storm events. Paleotempestology investigations were carried out for the southeastern part of Hainan Island. The storm deposits identified are interbedded within the aeolian coastal dune profiles on the Jianling coast. They are characterized by coarse-grained overwash deposits during the extreme storm events, as revealed on the basis of detailed stratigraphic division, grain size and magnetic susceptibility analyses. The age of the storms events was determined using the 14C and OSL dating methods, in combination with historical documents. When a storm surge hits the coast, the coastal dune may be overtopped or breached, and a low-lying dune associated with a large, flat terrain at the backshore is suitable for trapping the storm sediment to form a thick-bedded, sandy washover deposit. The Stockdon empirical equation was used to calculate the overwash height, indicating that the storm record at the Jianling site represents the product formed by several storms, with their return periods being 100 to 200 years. The result obtained implies that the coastal dune here contain important information on the intensity and frequency of occurrence of the South China Sea typhoons.

Abstract: In the present study, coastal dune deposits are analyzed to derive the information on historical storm events. Paleotempestology investigations were carried out for the southeastern part of Hainan Island. The storm deposits identified are interbedded within the aeolian coastal dune profiles on the Jianling coast. They are characterized by coarse-grained overwash deposits during the extreme storm events, as revealed on the basis of detailed stratigraphic division, grain size and magnetic susceptibility analyses. The age of the storms events was determined using the 14C and OSL dating methods, in combination with historical documents. When a storm surge hits the coast, the coastal dune may be overtopped or breached, and a low-lying dune associated with a large, flat terrain at the backshore is suitable for trapping the storm sediment to form a thick-bedded, sandy washover deposit. The Stockdon empirical equation was used to calculate the overwash height, indicating that the storm record at the Jianling site represents the product formed by several storms, with their return periods being 100 to 200 years. The result obtained implies that the coastal dune here contain important information on the intensity and frequency of occurrence of the South China Sea typhoons.
