• OBSERVATION AND MODELING OF RAINFALL INTERCEPTION IN EVERGREEN FOREST AND DECIDUOUS FOREST

抄録

The objectives of this research are to establish the effective factors for rainfall interception in forest area, and to develop an interception model with micrometeorology and forest structural character such as LAI and crown density. Throughfall, stemflow and some micrometeorological factors are measured at the evergreen forest and the deciduous forest in Takayama City, Gifu, Japan, during 2009 to 2010. The tank-like interception model, which is considered the meteorological and forest stand structural parameter, is developed, and simulates some rainfall events to assess its performance and discuss the effective factors for interception. The results and findings are as follows. Interception rates varied widely in the case of small gross rainfall events. At the evergreen forest, throughfall is simulated precisely, however, underestimated in the case of high intensity rainfall events. It is necessary to modify the tank model parameters of leaf drip water. At the deciduous forest, the interception model considered phenology shows better performance than the model fixed crown density. Phenology is one of the most important parameters for interception modeling.
