Short summary

This study examines the sediment transport during the 2004 Indian Ocean tsunami event on Phra Thong Island, Thailand. We use numerical simulations and sediment transportation models, and our modelling approach confirms that the beaches were significantly eroded predominantly during the first backwash phase. Although 2004 tsunami deposits are found on the island, we demonstrate that most of the sediment was deposited in the shallow coastal area, facilitating quick recovery of the beach.
