PROBLEM TO BE SOLVED: To provide a drift-sand flow analysis system and drift-sand flow analysis method capable of performing drift-sand flow analysis simply and accurately without limiting spreading place of sample sand.;SOLUTION: Artificial sand is spread into water at a predetermined point in the sea, a river, a pond, or the like, earth and sand including artificial sand is sampled from the water bottom every mesh formed by partitioning the flow range of the spread artificial sand every predetermined area, and the artificial sand is recovered from the sampled earth and sand. The identification information of the recovered earth and sand is read by a reader, the read identification information is fed to an analysis device, and flow analysis of the direction, flow rate, residence time or the like of the drift-sand flow is performed by the analysis device 34.;COPYRIGHT: (C)2006,JPO&NCIPI
