Abstract

There are various types of sand dune on the earth. These shapes can be broadly classified by the complexity of the wind, the amount of sand and vegetation. We make a numerical model of sand dune with vegetation. The main processes are saltation, avalanche, saltation suppression effect and growth of vegetation. As a result of numerical simulation, a crescent shaped dune called as parabolic dune appeared. As it increased the amount of sand, transverse-like dunes with vegetation developed.
