Main Article Content
Two sediment cores for the introduction study collected from Bang-Yai estuary, Phuket bay, Phuket province, Thailand were used to assess the levels of metal pollution (Pb and Zn) in sediment samples. Two grain-size fractions (>150 µm and <150 µm) of the sediment samples and heavy metal concentrations in 2003 were used to identify the layer of sediment during the Tsunami in 2547 B.E. (2004 C.E.). The results showed that the sediment layers in Core A are disturbed by the tsunami deposition at 24-26 cm depth, whereas the redistribution of the sediment was detected at a depth of 34-35 cm in Core B. In addition, it was found that the sedimentation rate after the tsunami event in Core A and B are 2.17 and 2.87 cm yr-1, respectively. In this study, the disturbed layers of the sediment samples by Tsunami deposition were attributed to the uniform trend of vertical sediment texture composition (grain-size >150 µm and <150 µm) from a depth of 9 cm. toward the end of Core A and from 7.5 cm. toward the end of Core B, respectively.
