抄録: | Experimental studies are made on the process of generations and developments of sand waves.These processes are very complicated because these are dynamic and three-dimensional and alsobecause these have important relation with the motion of water flows.In this experimental study, photographs of plan views of sand waves are taken every half aminute with a camera which is fixed over the channel. The longitudinal distribution of heightof sand waves and water depth are also measured along thc center line of the channel every 20minutes. Moreover, photographs of flow patterns on water surface are taken by the camera whichis carried with the equal velocity with the mean flow.Resultant films and datas are useful to understand the movement and development of in-dividual sand wave. Space-time distributions of various characteristic values of sand waves are alsoexamined. Some regularities in the process of generations and development of sand waves aremade clear. |
