| 抄録: | The process of development of ripples were investigated experimentally. The three-dimen-sional measurement of the bed configuration was made with supersonic bed elevation meters.The data obtained were processed by a computer system, and spatial distribution of bedelevation, bird's-eye view of bed configuration and spatial distribution of local erosion and ac-cretion of the bed during certain intervals (about 2 minutes) were displayed. The developingprocess of individual sand wave was investigated in detail. Consequently, it was found that theincrement of height of ripples was caused by a slant spiral flow, which scoured the sand bed locallyand violently and scattered sand particles downstream. |
