| Outline of Final Research Achievements |
Numerical simulation of water movement in snowpack is a important method for wet-snow avalanche forecasting, although it has not been established. In this study, we observed the water infiltration into dry snowpack during cold laboratory experiments, and developed the numerical method of it. The experimental results showed the limiting process of water entering into dry pore. The numerical simulation of infiltration was improved by including this effect.
