Boundaries of drainage basins shifted faster during past episodes of climate change, geologists suggest

Using a unique field site in the Negev, Ben-Gurion University of the Negev geologists have presented the first-ever time-dependent record of drainage divide migration rates. Prof. Liran Goren, her student Elhanan Harel, and co-authors from the University of Pittsburgh and the Geological Survey of Israel, further demonstrate that episodes of rapid divide migration coincide with past climate changes in the Negev over the last 230,000 years (unrelated to present-day climate change).
