Hydraulic Approach on the Snow Removal System with an Open Channnel

Abstract

The snow removal system with an open channel is studied by the hydraulic approach. The fundamental equations are derived by adopting the two-phase flow analysis. The continuity and momentum equations are obtained for snow and water phase. Increment of shear stresses which is caused by the snow transport is taken into account in the model. The results obtained are the threshold condition of snow movement, the increment ratio of water depth and the maximum snow conveyance rate in an open channel. Some of these results are compared with the experimental data and the agreement between the theory and experimental data is quite satisfactory.
