Outline of Final Research Achievements

In this research project, the water environment analysis and simulation models for watersheds including land and coastal areas were constructed in urbanizing watersheds in Asian monsoon regions. Firstly GIS-based distributed nutrient-load-runoff watershed models were developed in land areas and then three-dimensional eco-hydraulic models were made up for closed and semi-closed water bodies such as agricultural reservoirs and ponds, and coastal areas. In those modeling, satellite image remote sensing techniques and machine learning techniques were introduced to complement the scarcity of necessary data for the modeling. Finally the scenario analyses for implementing the measures for water quality conservation and improvement were conducted by using the developed models, and the roadmaps for practicing the measures were recommended.
