The 32 km Afsluitdijk separates the IJsselmeer (right) fromthe North Sea (left), protecting thousands of km² of land.
The Zuiderzee Works (Dutch: Zuiderzeewerken) are a manmade system of dams, land reclamation and water drainageworks, the largest hydraulic engineering project undertaken by the Netherlands during the twentieth century. The project involved the damming of the Zuiderzee, a large,shallow inlet of the North Sea, and the reclamation of land in the newly enclosed water using polders. Its main purposes are to improve flood protection and createadditional land for agriculture.
Together with the Delta Works, the American Society of Civil Engineers declared the works among the Seven Wonders of the Modern World.
