Surface instability in windblown sand.
We investigate the formation of ripples on the surface of windblown sand based on the one-dimensional model of Nishimori and Ouchi [Phys. Rev. Lett. 71, 197 (1993)], which contains the processes of saltation and grain relaxation. We carry out a nonlinear analysis to determine the propagation speed of the restabilized ripple patterns, and the amplitudes and phases of their first, second, and thi...
متن کاملSimulation, Prediction and Experiment on Windblown Sand Movement and Aeolian Geomorphology
In the evolution processes of wind blown sand movement and aeolian geomorphology, it always contains some complex behaviors, for example, the nonlinear character of turbulence and attractors, the stochastic character of wind gust, liftoff and movement of sand, the interaction among wind field, sand movement, electric field in wind blown sand flux and thermal diffusion, multi-scale character fro...
متن کاملAn Experimental Investigation into the Arching Effect in Fine Sand
In the current paper results of a well instrumented experimental procedure for studying the arching effect in loose and dense sand are presented. The apparatus comprises concentric circular trapdoors with different diameters that can yield downward while stresses and deformations are recorded simultaneously. As the trapdoor starts to yield, the whole soil mass deforms elastically. However, afte...
متن کاملSand Movement patterns in the south of Iran
Wind regime data from the Jask meteorological station from a 20-year statistical period (1985-2005) was analyzedusing the Fryberger method to investigate sand drift potential (DP) in this area. The resultant drift potential anddirectional variability of wind were calculated and illustrated. Average annual sand DP was estimated to be 460vector units (VU), and the sand flux is 51 m3/m.year. There...
متن کاملExperimental investigation of face stability of shallow tunnels in sand
The face stability of shallow tunnels was investigated with small-scale model experiments at single gravity. Aim of the research was to detect the evolution of failure mechanisms in dense and loose soil samples with varying overburden above the tunnel. Moreover, the quality of proposed theoretical/numerical approaches for the determination of a necessary support pressure pf was assessed. The re...
