| Outline of Final Research Achievements |
In the emerging and developing countries in Southeast Asia, organic pollution has been rapidly spreading in rural areas and closed water bodies due to the progress of urbanization and mixed residence accompanying economic development. It is an urgent issue to conserve the water environment of closed water bodies while maintaining high agricultural productivity. In this project, GIS-assisted watershed models for land areas, hydraulics-ecosystem models for water areas, and integrated models of both have been developed by targeting the watersheds of Kyushu in Japan as well as in Vietnam. When developing the models, artificial intelligence techniques, machine learning techniques, and satellite remote sensing techniques have been actively introduced to compensate for the unavoidable data scarcity in the Southeast Asian watersheds.

| Academic Significance and Societal Importance of the Research Achievements |
流域圏における水質環境は，陸域上流から下流の閉鎖性内湾に至る流域圏の物質フロー系によって形成されるため，流域圏の水質保全のためには，本研究で目指したように，陸域と海域を個別に考えるのでは無く，連続的に捉え，陸海域流域圏全体の水循環系と物質循環系を統合的に俯瞰する，いわゆる陸海域統合－流域圏水環境管理が極めて重要となる．
また，東南アジア流域圏では，流域圏管理モデルの構築に必須となる各種データが利用できないことが多いため，本研究で目指したように，人工知能技術や機械学習技術，衛星リモートセンシング技術などを利用して，このデータ寡少性をいかに克服するか，これも極めて重要となる．
