Current Research Topics

My current research topics focus on Integrated River Basin Managements.  I am investigating the environmental issues in river basins mainly through field monitoring and physical modeling with special emphasis on hydrogeomorphological viewpoint.  In addition to these natural environmental problems in waters, I am currently interested in basin-wide water resources management which relates the natural water environment with social activities of human beings. I begin investigating the basin-wide water resources problems through GIS analysis and mathematical modeling.


Integrated River Basin Management:

     (1) Monitoring and Analysis of Stream Temperature in a River Basin
     (2) Development of Integrated Assessment Methods for Social and
          Natural Environments Based on Basin-Scale Hydro-Geomorphology
     (3) Vegetation Dynamics in a River Channel
