Abstract

In order to get the data about bed-load transport rate and bottom topography changes under storm wave conditions, field equipments were newly developed and tested at the T-shaped Observation Pier(TOP) on the Ogata coast facing the Japan Sea.The surf sled with a pressure senser can precisely detect the spatial water depth changes along the survey lines. Based on the compiled data, the 3D bottom topography changes for a winter season connect with the appearance of a dip and shoal system on the Ogata coast. The bed-load sampler has also developed to operate in rough sea state in a plane bed conditions. The data were well fitted with the law of cross-shore bed-load transport proposed by Kawata( 1989a).
