Learn how atmospheric rivers form, why they cause mega-storms and flooding, and what new science reveals about their growing ...

How do rivers choose their path? Why do some rivers form single channels, while others divide into many threads? The questions may sound simple, but they are plagued by dynamic and complex forces that ...

The water pressure of a river can cut deep into a riverbed. Sediments from the riverbed are carried downstream, creating a deep, narrow channel. This process, known as downcutting, represents the ...

A new Stanford study challenges the decades-old view that the rise of land plants half a billion years ago dramatically changed the shapes of rivers. Rivers generally come in two styles: braided, ...

Rivers are Earth’s arteries. Water, sediment and nutrients self-organize into diverse, dynamic channels as they journey from the mountains to the sea. Some rivers carve out a single pathway, while ...

A new Tulane University study published in Science Advances sheds light on how floods influence the way rivers move, offering fresh insight into how changing flood patterns may reshape waterways and ...

The second atmospheric river to hit the West Coast in as many weeks has stalled over Southern California, dumping more than 9 inches of rain over 24 hours in some areas near Los Angeles. Streets are ...
