Winter flood of 1993: real and counterfactual scenario

Caption

Comparison of return periods at 516 river gauges in Germany between the winter flood of 1993 (left) and a counterfactual, i.e. hypothetical but not unrealistic, scenario in which the rain would have fallen 50 kilometres to the north-east (right). More serious events are recognised in the counterfactual scenario.
