The purpose of this project is to clarify the effects of global warming on forests, water resources and sediment disasters in Japan. At first, the estimation of possible changes in precipitation and temperature in Japan was investigated by the results of the reconstruction of paleo climate using dendrochronology and stable isotope. The results of the numerical simulations by GCMs were also taken into accounts.Based on this estimation, the effects of global warming on forests, water resources and sediment disasters were evaluated.A model was developed for estimating changes in water resources. Possible changes of water balances, such as river discharge and evapotranspiration was evaluated by the model.Increase of sediment yield was considered to be inevitable because of the increase of precipitation, resulting in the increase of serious disasters.

该项目的目的是澄清全球变暖对日本森林、水资源和沉积物灾害的影响。首先，利用树木年代学和稳定同位素重建古气候的结果，研究了日本降水和温度可能变化的估计。在此基础上，分析了全球变暖对森林、水资源和泥沙灾害的影响，建立了水资源变化的估算模型。通过模型计算，分析了流域水量平衡可能发生的变化，如径流量、蒸散量等，认为随着降水量的增加，流域产沙量增加是不可避免的，从而导致严重灾害的增加。
