摘要：

An experimental evidence for kinetic roughening in a micromodel of mountain ranges is presented. We have observed that during the watering of an initially smooth ridge made of a mixture of silica sand and earthy soil the surface, evolves into a shape analogous to actual mountain profiles with self-affine geometry. For the exponents describing respectively the temporal and the spatial scaling of the surface width beta almost-equal-to 0.9 and alpha=0.78 +/- 0.05 have been obtained. The latter value is in very good agreement with alpha=0.8 +/- 0.1 we have calculated for genuine transect profiles.
