The floods causing damage across much of central
Europe are a sign of catastrophes to strike as the
continent's climate gets harsher. In the German town of
Passau on 3 June 2013, waters rose to their highest
level since 1501. At that time, the floods in Czech
capital Prague were beginning to recede but Dresden,
Germany, was preparing itself for the river Elbe to rise 5
metres higher than normal. "Several factors are
responsible", says Stéphane Isoard of the European
Environment Agency in Copenhagen, Denmark. "It was
spring, so snow was melting from the mountains," she
says. When two months of rain fell in two days, the
water had nowhere to go because the ground was
soaked. Climate change also causes heavier rainfall,
and might be partly to blame. However, Isoard points
out that bad land management is just as important. "In
urban areas, there is less opportunity for water to
infiltrate the soil. With more floods inevitable, Europe
needs to adapt," Isoard says. Some work is already
under way. Wetlands are being restored around
stretches of the Danube. Green spaces like this can
absorb extra water, making floods less severe. "Over
the last 20 years, events like this have become more
common," says Iain White of the University of
Manchester in the UK. "Central Europe has improved its
flood responses since 2002, but there comes a point
where you can't defend," he maintains
