| Outline of Final Research Achievements |
In order to mitigate coastal erosion prevailing all over the world, it is essential to estimate sediment movement in the watershed scale, since sediment delivery from land to ocean must be influenced by the watershed scale. This study aims at the development of a framework in which sediment movement is estimated by using luminescence measurement of sediment particles. The luminescence of sediment grains is considered to reflect the exposure time to light during the sediment movement. The sediment transport rate is estimated by combining the luminescence property with light exposure model.
Based on the luminescence measurement, an innovative technology has been developed to estimate sediment movement in the watershed scale. The methodology was found to be applicable to identify the sediment deposition due to historic tsunamis. The validity of the skill was confirmed by a series of field studies conducted at Sendai, Kirikiri, Fukui, Yonago and Miyazaki Coasts.
