The present study aims 1) to present field data obtained through intensive and continuous measurements of both waves and swash-zone morphology by deploying many ultrasonic wave gages along the Hasaki observation pier and 2) to elucidate erosional processes occurring in the swash zone, focusing on the erosion of a berm under the action of storm waves based on the data.
