Abstract

 In order to investigate topographic change in gravel beaches using a UAV-SfM/MVS survey, it is important to re-construct a high-accurate three-dimensional model. The aim of this study was to clarify an optimum analysis method for the UAV/SfM-MVS survey at gravel beaches and the characteristics of topographic change in the Shichirimihama Ida coast was investigated from the three-dimensional model. As a result, it was found that a reproducibility of the three-dimensional model was influenced by a parameter in the “Align photo” analysis. Moreover, it was revealed that deposition was caused by low and long period waves in the Shichirimihama Ida coast.
