A 2002 Texas megaflood carved a 2.2km canyon in three days

By John Timmer.

Most of the dramatic features of river basins—canyons, gorges, and so on—formed through rather mundane processes, primarily the slow erosion caused by a constant flow of water and seasonal floods. But researchers have also identified a few cases, both on Earth and Mars, where features seem to have been formed by sudden massive flooding (on Earth, these are often associated with glacial melting). We have geological evidence of these catastrophic events, and models that reproduce their behavior but, because they’re extremely rare, it has been impossible to test how well these models do when compared to a real event. Scientists have now identified a Texas flood that carved a seven meter deep canyon in 2002 that presents just such a rare opportunity… Read More>>
