Prague city centre<br />

The Climate<br />

Challenge<br />

Prague, the capital city<br />

of the Czech Republic, is<br />

located in a temperate climate<br />

zone. Vltava River, the<br />

longest in the country, flows<br />

through its historic centre.<br />

In 2002 Prague experienced<br />

severe 500-year flooding<br />

with total damages of CZK<br />

24 billion (Eur 1 billion).<br />

This event was recognised<br />

as one of the most expensive<br />

weather-related disasters<br />

in the city’s history.<br />

Future climate scenarios<br />

furthermore predict an<br />

increase in the number and<br />

intensity of extreme events<br />

such as flooding. Wetter<br />

winters, dryer summers with<br />

more precipitation extremes<br />

and weather fluctuations in<br />

general are also expected.<br />

The Adaptation<br />

Response<br />

A flood protection system in<br />

Prague had been developed<br />

for decades, but after the<br />

500-year flood in 2002, implementation<br />

of flood control<br />

measures by the Prague<br />

municipality substantially<br />

sped up. Moreover, the original<br />

plans were upgraded to<br />

increase resilience against<br />

extreme flood events, to<br />

protect most parts of Prague<br />

from floods with a 1 to 500<br />

years return period.<br />

The flood control measures<br />

implemented include fixed<br />

barriers (levees, dikes), mobile<br />

barriers and additional<br />

measures such as closures<br />

and pumping systems in the<br />

canalisation. The total length<br />

of flood protection measures<br />

(fixed barriers, solid concrete<br />

walls and mobile barriers)<br />

after the completion of<br />

all stages is app. 19,255 km,<br />

of which mobile measures<br />

are 6,925 km.<br />
