Heat, dry conditions, and the resulting low flows in rivers and lakes characterized the summer months of 2003, 2015 and 2018 in Europe. Another low-flow period is on the cards for the summer of 2020. Researchers from the University of Freiburg, working with the Universities of Trier and Oslo, Norway, have presented a new method which can help scientists tell more precisely how vulnerable rivers are to drought conditions. Their findings are published in the journal Hydrology and Earth System Sciences.
