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 ...
PARIS, Mar. 11 -- Three physicists have developed a simple mathematical formula to describe the formation and mysterious traits of sand dunes -- the shifting, piles of blowing sand whose march can ...
The 15-strong team joined the Alderney Wildlife Trust to remove sour fig, which is thought to have been introduced after World War Two to cover wartime bunkers, but posed "a significant threat to the ...
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 ...
Anyone who has seen giant sand dunes, the tall ones stretching many hundreds, even thousands, of feet across the desert floor, has surely wondered how they get to be so big. Scientists, too, have ...
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, ...
Once Martian sand grains hop, they don’t stop. That’s the conclusion of a new study that finds sand can move on Mars without much windy encouragement. Mars’ sandy surface has clearly been shaped by ...
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, ...
