The cause l.jpg
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 l.jpg
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 l.jpg
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 l.jpg
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 l.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.

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.
