A simulator for powder snow avalanches is developed using the software "Delphi". The numerical model developed by Fukushima is used. This model is based on the thermal model and uses the concept of the snow entrainment coefficient. The simulation model contains four ordinary differential equations; i.e. the mass conservation equations for air and snow particles, the momentum equation and the conservation equation for the kinetic energy of turbulence. These equations can be numerically solved by any numerical scheme such as the Runge-Kutta method. The simulator has the functions of carrying out the numerical calculation and drawing the several graphs for the physical items such as the variation of the travel speed, the maximum avalanche height, the concentration of snow particles and the kinetic energy of turbulence so on. The printing out of these graphs is also possible by the developed avalanche simulator.
