The model, published in Physical Review Fluids, is the first to describe interactions between sand dunes and obstacles. By analysing how currents are deflected in the presence of an obstacle, they ...

Sand dunes are amazing. They sing, they move, they organize into regular structures—and then those structures can fall apart. Dunes can collide and combine into a single dune, and a single dune can ...

The 15-strong team joined the Alderney Wildlife Trust to remove sour fig, which is thought to have been introduced after ...

Dunes of sand and other granular materials can be found in large fields on Earth, Mars and beyond. Dune fields tend to self-order into spatial patterns and the physics underlying this ...

Understanding dunes is important, since he who controls the Spice controls the Universe That’s the last Dune joke, I promise. Understanding the mechanisms behind desert sand dune formation and ...

The so-called Abelian sandpile model has been studied by scientists for more than 30 years. Even though the sandpile model serves as the archetypical model to study self-organized criticality, ...

Sand dunes migrate across landscapes by interacting with and repelling one another in what scientists have called "interesting and beautiful physics." These natural formations, which often cover ...

Figure 1: Star dunes using a real-space cellular automaton model. Although the simulation of complex dunes would gain from a more detailed airflow modelling including three-dimensional recirculation, ...
