| Outline of Final Research Achievements |
Mountainous basins are the strategic area of both water resources and flood control in Japan. Therefore, the accurate reproduction and reliable prediction of runoff from mountainous basins are significant issue. In order to develop reliable hydrological model, this study investigate the property of the parameters in the storage-discharge relationship for low flows and floods. In addition, the hydrological analysis are carry out to estimate the runoff variation in the future using GCM data. The results show that, a) the two parameters for low flow have inverse relationship, b) the two parameters for floods have the relationship which is represented by exponential function. c) This study also examined the parameters which can be more convincingly used in practical applications. Furthermore the runoff of monthly mean and annual mean from 2080 to 2099 was estimated using climate projections of GCM and the hydrological model of this study.
