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 ...

Scientists have used down-scaled laboratory models to show how sand dunes move through a landscape, revealing the conditions that determine whether they will pass through hurdles in their path -- like ...

Sand in an hourglass might seem simple and straightforward, but such granular materials are actually tricky to model. From far away, flowing sand resembles a liquid, streaming down the center of an ...

The technology used to predict sand and dust storm (SDS) severity has for decades systematically overestimated when and where sediment is transported across Earth's surface, a new study shows.
