| Outline of Final Research Achievements |
An international research group on study of beach-dune morphology was established with Professor Ranasinghe of IHE Delft in the Netherlands. For effective collaborative research, we decided that the principal investigator joined to the Professor Ranasinghe's Chair and Associate Professor Dastgeib visits the principal investigator's laboratory regularly. It is a great achievement to develop the active international research base. With this research base, sufficient research results on coastal sandy beach-dune system such as sediment supply from rivers to coast, long-term shoreline change and wind field around coastal sand dune were published in multiple international journals.

| Academic Significance and Societal Importance of the Research Achievements |
海岸の地形変化は様々な要因による複雑なメカニズムに起因しており，未だに高精度で予測することが困難な事象である．この複雑なメカニズムの中から主要な多くの事象を抽出し，予測精度を向上させることは学術的に極めて重要である．我が国においては既に海岸侵食が進行しており，気候変動の影響でさらに沿岸災害リスクが増大することが懸念されている．海岸地形変化の予測精度を向上させることにより，より適切な対策につなげることは，今後適応策を検討する上でも極めて重要である．
