Sand dunes are iconic landmarks of deserts, but can also put human infrastructures at risk, for instance by forming near buildings or roads. We present a simulator of sand erosion and deposition to predict how dunes form around and behind obstacles under wind. Inspired by both computer graphics and geo-sciences, our algorithm couples a fast wind flow simulation with physical laws of sand saltation and avalanching, which suffices to reproduce characteristic patterns of sand deposition. In particular, we validate our approach via a qualitative comparison of the erosion and deposition patterns produced by our simulator against real-world patterns measured by prior work under controlled conditions.

Code

We provide a code base associated with this paper. Given a terrain described by a height map, you will be able to run our simulation pipeline that iteratively simulates the wind above the terrain and update the sand transported and deposited by this wind. This finally produces accurate sand landscape with for example natural sans dunes or erosion patterns around buildings appearing. Gitlab link
