Abstract: Sand samples were collected at 18 beaches and from rivers that supply sand to those beaches, to examine the supply sources of beach sand of on Awaji Island. Sand colors were analyzed using a simple color analyzing method proposed in our preceding papers, and relationships between sand color anddrainage basin geology were investigated. Differences in river sand were relatively obvious, owing to distinctive colors of geological strata on Awaji Island. Differences in beach sand were unclear because of weathering, beach nourishment processes, or sand transport by coastal current.
