| Research Abstract |
In this present study, we developed the system to evaluate forest water use in large scale area to integrate the method of objective model redundance developed by Crout et al. (2009). Our system is besed on Biome-BGC, which is one of the forest ecosystem model, with introducing exponential tank model (Kondo et al., 1992) to take into account the characteristics of discharge at mountainous forest watershed in Japan. We checked the model performance of new developed system using observed data obtained at mountainous forest experimental watershed located in Kyushu region, Japan and investigated significant model parameters on reproduce the daily discharge and evapotranspiration in Japanese forest ecosystem.
