The erosion of large natural channels by flowing water -- gully erosion -- can wreak havoc on fields, roads, and buildings. In some cases, the sudden expansion of gullies even claims human lives. Geographers are the first to show a worldwide link between heavy rainfall and the speed at which gullies expand. With predicted climate change, gullies may erode up to three times faster.
