IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Analysis of extreme hydrological events in major river basins in japan under climate change
Author :
To clarify the hydrological impact of climate change at a regional scale, for application to water resources management and river disaster prevention, distributed hydrological modelling was conducted for three major river basins in Japan using a super high-resolution atmospheric general circulation model (AGCM20) and Coupled Model Intercomparison Project phase 3 CMIP3) multimodel data. The results show that the hydrological impact of climate change is larger in the northeastern snowy region than in the south-western warm–humid region; the climate change impact on extreme hydrological events, such as the magnitude of the 1/100 annual maximum flow or the 1/10 minimum flow, will differ by region; and the projection uncertainties caused by the relatively coarse resolution of current conventional GCMs can be decreased significantly by the simple multi-model ensemble approach applied in this study.
