Netherlands North Sea Protection Works Team F: Sandy Everett Omar Holguin Rick Marmolejo Mario Sandoval February 6, 2008
The Cause • For the past 2000 years, the Dutch have been trying to reclaim land from the North Sea. • The first settlers, the Frisians, built the first dykes called terpens. • The terpens failed in 1287, and flooded the country. http://geography.about.com/od/specificplacesofinterest/a/dykes.htm
After the Flood • The Zuiderzee Bay was created from the flood. • Slowly dykes were built and polders (land reclaimed from water) were formed. • Windmills were used to pump water off the fertile soil. http://geography.about.com/od/specificplacesofinterest/a/dykes.htm
Looking at the Barrier • Storms in 1916, led the Dutch to start a major project to reclaim the Zuiderzee, from the North Sea. • A 19 mile long, 100 yard thick dyke called Afsluitdijk (the Barrier Dyke) was built during 1927 to 1932. • This turned the Zuiderzee into a freshwater lake to be called IJsselmeer. http://geography.about.com/od/specificplacesofinterest/a/dykes.htm
Benefits of Construction • Turned the Zuiderzee from a dangerous area into the tame shallow inlet of the North Sea, IJsselmeer. • This change created 1,650 km2 of dry land for the Dutch. Equal to over 400,000 soccer fields! • Protected central Netherlands from the brutal effects of the North Sea. • Increase in Dutch food supply with the addition of new agriculture land. http://www.clarkcompanies.com/Site%20Revision/images/Large%20Project%20Photos/Brown%20University%20Stevenson%20Field.jpg
Current Status • Today, the elevation is 36 feet, and approximately 27 percent of the Netherlands is below sea level. • 60 percent of the country’s 15.8 million people live in this area. • The size of the Netherlands is compared to Connecticut and Massachusetts combined.

Kornwerderzand • 25 discharge sluices. • Periodic discharge is necessary since the lake is continually fed by rivers, streams, and polders draining their water into lake IJsselmeer. www.googlemaps.com
The Second Part of the Plan • Flood Defense System called Delta Works consist of dams and storm surge barriers. • Delta works executed between 1950 and 1997. • Storms in 1953 killed 1,800 people and hundreds of thousands of livestock. http://images.google.com/imgres?imgurl=http://www.deltawerken.com/modules/mediagallery/images/maps/dammen.jpg&imgrefurl=http://www.stormfront.org/forum/showthread.php/country-thread-netherlands-425161p2.html&h=400&w=400&sz=72&hl=en&start=86&tbnid=8KFVIjj m2AHHM:&tbnh=124&tbnw=124&prev=/images%3Fq%3DZuiderzee%26start%3D72%26gbv%3D2%26ndsp%3D18%26hl%3Den%26sa%3DN
