We present a simple one-dimensional model to describe the evolution of a transverse dune field. The model is characterized by the distances between the dunes and their heights, which determine the inter-dune sand flux. The model reproduces the observation that the dunes in a given field have...

We present experimental and theoretical studies of the shape of heaps. In the simplest case one has a cone with an angle of repose. A simple 1d model is presented and solved analytically to obtain this angle from the properties of individual grains. This model is generalized to take into account...
