the cause
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.

after the flood
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.

looking at the barrier
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.

benefits of construction
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.

current status
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.

the second part of the plan
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.
