Abstract

This study attempts to utilize the X-ray Fluorescence Analysis (XRF) in the coastal erosion/accretion survey. Sand samples are obtained on foreshore beaches (20 locations) along the Enshu-Nada Coast, from the inlet of Imagire to Cape of Irago. The XRF instrument can detect 23 chemical elements from a sand sample and 8 chemical elements of Sb, Sr, Rb, Fe, Mn, Ti and Ca are detected from all samples. In these elements, the content (ppm) of Fe is highest in all locations. The cluster analysis is demonstrated using these 8 elements and the result is compared with the data of beach width. The clusters of 20 locations by the analysis can be mostly explained by the present beach condition (wide/narrow) and the trend of beach erosion/accretion in recent years.
