Abstract
Damages of wind blown sand were investigated at Makuhari artificial beach in Chiba Prefecture, the Chigasaki coast in Kanagawa Prefecture and Nakatajima Sand Dune in Shizuoka Prefecture. Fine sand was transported by wind and deposited on the promenade behind the beach, causing obstruction against traffics. In order to study these phenomena, field study on wind blown sand consideringg rain size effect was carried out at Kujukuri beach. It was confirmed that selective transport of fines and is important and this results in sorting effect in an extensive area.
