| Outline of Final Research Achievements |
I tackled development of versatility- and simplicity-conscious process-based landscape evolution models (LEMs) which can use fine resolution digital elevation models (DEM) by Air-borne laser mapping as initial condition data, and applied them to actual topography in Japan to evaluate their performance.
The developed LEMs returned good results comparing with previous Japanese geomorphological studies in case of using about 25 meter resolution DEM for around 100 square kilo-meter drainage area. On the other hand, it was revealed that we should solve flow-routing algorithm problems to carry out the simulation by using more high-resolution DEM.
