dc.description.abstract | In order to establish the mechanics of sand transport in both water streams and airflows, the mechanism of saltation of a single sand particle should be considered. Aftersome considerations on the equation of motion of an accelerating spherical particle in fluid, an approach to establish the mechanics of saltation of a single sand particle in streams, including the sliding and rolling motion, is presented. It was found that the theoreticalresults of the rolling distance and distribution characteristics and the velocity of a sandparticle are in good agreement with experimental ones. A theory of the saltation of asand particle by collision of the rolling particle with a bed sand particle is established.The theoretical results of the saltation height of a sand particle and the (listributioncharacteristics are in good agreement with experimental ones. | en |
