Аннотация:The new mathematical model of slushflow dynamics is developed. The slushflow is considered as two-layer flow. The lower layer includes a pure liquid phase (water), while the upper layer contains a floating water-saturated snow (slush). The equations of mass and impulse conservation for each layer are written. These equations include the interaction and the mass exchange between layers, as well as between the lower layer and snow cover. The series of numerical calculations for a uniform slope has been carried out. The slushflow structure is investigated, and dependencies of the depth, flow velocities and the front coordinates on the parameters of the model has been received. An effect of exhaustion of the lower water layer was established when the value of the coefficient of entrainment is not large.
