| Outline of Final Research Achievements |
To evaluate the impacts of climate change on river discharge, we applied a hydrological simulation to one of the major river basins in Japan, located in a cold and mountainous region （Tedori river basin）. To improve the performance of our model simulation, we conducted field observation by various method such as time-lapse camera photograph analysis, aerial photograph analysis by UAVs (unmanned aerial vehicles), and mulch function meteorological monitoring. By using actual field observation data-sets, we could calibrate our model parameters such as rainfall-snowfall threshold temperature, density of snow, snow depth etc. These results will contribute to improve the reproducibility of our model simulation applied for the cold mountainous regions.
