Research Abstract

Inter-comparison study is effective to find general lows of catchment rainfall-runoff processes. This study collected previously reported observation data of rainfall and discharges from mountainous small catchment in Japan and constructed database. We also developed methods to inter-compare catchments using hydrological tracer, such as stable isotopes of water.
