Profile

• Profile

  "Water" is the most essential component all beings entirely depend on. I am working on research about the most essential element "Water" from the viewpoint of "Water Resouces" and "Water Environment". In regards to education, I place the most importance on "Self-teaching and self-learning" based on dialogue.

Research Topics, Overview of the research

• Research Topics

  Water Resources and Water Environment

• Overview of the research

  My research area includes water resources and water environment to harmonize water we utilize with catchment environment and eco-systems. I have been developing computational models of water flow, substance transport, and stochastic fish behavior in rivers, canals, and ponds. I believe these models would be powerful tools to provide information about water control for creating an ideal environment for all living creatures including human beings.
