Outline of Final Research Achievements

It is investigated to improve the estimation method of rainfall interception in order to improve a real-time flood prediction model with phenology by satellite images. The rainfall interception model with phenology information by MODIS NDIV images is developed. However the interception model with phenology information does not indicate better performance than another model with annual averaged crown densities distribution. It is suggested that canopy interception is not much affected by seasonal changes of canopy structures rather than other factors and the model is not suitable for real-time simulation. On the other hands, the produced interception model indicates better performance to estimate the interception loss with annual averaged crown densities information. It is suggested that the model is suitable to evaluate a typical interception loss for a specific basin.
