ZUIDERZEE WORKS, HOLLAND. IJsselmeer, 1973. The Zuiderzee Works are a man-made system of dams, land reclamation and water drainage works, and the largest hydraulic engineering undertaken by the Netherlands during the twentieth century. Between 1927 and 1932 a 30-km-long dam, known as the Afsluitdijk, was built across the Zuiderzee, a large body of water along Hollandís northeastern coast, separating it into the outer Waddenzee, which is open to the North Sea, and the inner Ijsselmeer. Its main purposes were to improve flood protection and create additional agricultural land by means of polders. Over the years dykes have been used to create more polders, which have been drained with pumps or windmills. The 1973 image shows the partially completed dyke that allowed for the creation of the southernmost polder, which by 2004 was covered with farms. The patch of lighter blue in the images is Markermeer: this is a freshwater reservoir that acts as a buffer against floodwaters. CDREF00438 . See image number SP1140986 for this view in 2004 These pictures are from 'One Planet, Many People - Atlas of our changing environment'. Visit www.earthprint.com.
