The Conversation: Rivers can suddenly change course – scientists used 50 years of satellite images to learn where and how it happens. “Throughout history, important cities around the world have flourished along river banks. But rivers can also be destructive forces. They routinely flood, and on rare occasions, they can abruptly shift pathways. These ‘channel-jumping’ events, which are called avulsions, have caused some of the deadliest floods in human history…. In a newly published study, I worked with colleagues to map the global distribution of avulsions on river fans and deltas. We used satellite images of over 100 rivers from 1973 to the present, providing a half-century of bird’s-eye views of global river evolution.”
