The water cycle is one of the most precious environmental assets on Earth. It is precipitation and runoff that allow life forms (including us) to flourish on land. But water circulation isn’t regular in space or time, and the extremes of both flood and drought are hazardous. We need to understand how these happen.
Much of what happens in the world is described as ‘unprecedented’, whether it is political events, the COVID-19 pandemic or flooding. History never repeats itself exactly, of course, but floods do at least have precedents. Understanding how they occurred in the past can help us deal with those yet to come.
