It's not rocket science - POLDERS, LAND RECLAIMED FROM THE SEA

C'est pas sorcier

Published on May 15, 2013
About :

The official channel of the France 3 show. C'est pas sorcier, the magazine of discovery and science. The Netherlands deserves its name. Its surface is completely flat. No mountains, no hills! In Dutch, Hol-land even means hollow country. In fact, 24% of its surface is below sea level. The country is so flat that man has had to build dikes everywhere to protect himself from the floods that constantly threaten it. Fred and Jamy explain everything to us about this daring fight by man against the waters. Why does the topographical situation of the country favor floods? How do we ensure the solidity of the dikes that protect the land from the assaults of the sea? How do we proceed to dry out the soil of what will then become a polder? What are the techniques now used to avoid the many disasters that the country has experienced in recent centuries?
