Outline of Final Research Achievements

This study analyzed the decadal-scale field observation datasets in order to clarify the systematic three-dimensional behavior of coastal morphological systems along the Ishikawa Coast, Japan. During the adaptation processes to the new environmental conditions under various human impacts, the inter-annual and large-scale transition of multiple sandbars were repeated in qualitatively similar way, while the inter-cycle comparison indicated considerable differences in the extent and magnitude of bar migration. Additionally, an image processing system for the video observation from small unmanned aerial vehicles or network cameras was developed to efficiently measure the coastal morphological changes.
