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 ...

The prediction of the angle of repose for raised mounds of dry cohesive granular material is a long-standing problem in the natural sciences and in industry. Using numerical (particle-based) ...

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, ...

Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at www ...

Cambridge scientists have used downscaled laboratory models to show how sand dunes move through a landscape, revealing the conditions that determine whether they will pass through hurdles in their ...
