| Outline of Final Research Achievements |
In this study, first, in order to understand the basic water environment characteristics of tidal flats, we carried out field observations at the Shirakawa and Nakatsu tidal flat. At this time, I also conducted a survey using an low altitude remote sensing method using a drone in order to easily monitor the aquatic environment. As a result of the survey, it was found that the tidal flats have extremely rich ecosystem services, but they are vulnerable to environmental changes in the short term, such as being severely damaged by sudden disasters such as heavy rain. Therefore, in order to investigate what kind of impact will occur in the tidal flat in the future, we analyzed the changes in the heavy rainfall event after climate change in the basins and clarified its characteristics using d4PDF.
