Popis: Field observations of bed configurations and flow patterns have been carried out under floods in the Hii River which is a typical sand-bedded river in Shimane prefecture. The observation plan is comprised of three components; the measurement over wide range by using RC-boat and a model plane-loaded camera, the precise measurement over small range from abridge, and water-level measurement.In this observation plan, time series of three-dimensional bed configurations data were successfully obtained by RC-boat for the first time under June 28-29 flood and July 12-13 flood. In this paper, the method of measurement and data analysis are described and the characteristics of sand-bars movement is discussed.
