In this paper, estimation of snow particles motion velocity and snow-drift density by mathematical modeling is studied. The snow particles flow is modeling from fluid dynamic concepts and micro-continuum approach (couple stresses fluid [۱]). The present approach is compared to conventional classical approach of logarithmic law of snow-drift density ([۲], [۳]). It is shown that, the present approach yield better results than that of conventional approach.
