| Research Abstract |
To examine effects of factors associated with flash flood and processes of flash flood, hydrological observations and simulations were conducted in an alpine catchment. Observation and simulation results suggest that runoff response of the study catchment is quick even during prolonged rainfall event and both localized precipitation in a sub-catchment and quick runoff from high altitude areas with thinner soil layer contributed rapid increase of river water level during a short-duration intensive storm. The hydrological simulation was applied to catchments covered by volcanic ash and showed that area of overland flow in a catchment is possibly an index of debris flow occurrence.
