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 ...

Dutch Ph.D. student Mathijs van Ledden has demonstrated that the often used rule of thumb 'the calmer the water, the finer the bottom sediment' is not always true. In addition to the flow rate, a ...

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, ...

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 ...
