| Outline of Final Research Achievements |
The mathematical model that can estimate the annual load of DOC, Dissolved Organic Carbon, from the forested catchment was developed on this research, and additionally, the possibility of the adapting that model to another watershed was researched.
For the runoff system, a semi-distributed hydrological modeling unit (‘modified-TOPMODEL’) was installed. The results of storm event calculation showed that the model performed well for the middle stream.
For adapting the developed model simulated to another catchment, the investigation was carried at Miuchi experimental watershed in Aichi, Japan. The increasing DOC concentrations were observed in the rain event when the rain caused the increasing discharge. The factor affected on the DOC concentration in the rain event is also considered the amount of DOC in the hot spot. That DOC dynamics in the catchment would be similar at Mizugaki Exp., therefore we supposed the developed model is possible to adapt to another catchment.
