What is the dike system?
Dikes used to hold back water are usually made of earth. Sometimes, dikes occur naturally. More often, people construct dikes to prevent flooding. When constructed along river banks, dikes control the flow of water. By preventing flooding, dikes force the river to flow more quickly and with greater force.
How do the Dutch keep the water out?
The Dutch are threatened by flooding from both the sea and from rivers. To keep low-lying land free of water, they use dikes, which are walls that are built to keep water out. Along with the dikes, they use continuously operating pumps. If the pumps stopped, water would eventually seep back into low-lying land.
How do the Delta Works work?
Constructed between 1954 and 1997, the works consist of dams, sluices, locks, dykes, levees, and storm surge barriers located in the provinces of South Holland and Zeeland. The aim of the dams, sluices, and storm surge barriers was to shorten the Dutch coastline, thus reducing the number of dikes that had to be raised.
What was the Delta Project?
The project comprised of laying 13 dams, including barriers, sluices, locks, dikes and levees, to reduce the Dutch coastline’s size and protect the areas within and around the Rhine-Meuse-Scheldt delta from North Sea floods. The project was finally completed in 1997, at a cost of $5bn.
Where are dikes used?

Where does the Delta Plan start?
This map shows the locations of project and non-project levees in the Delta. The project levees begin on the left bank of the Sacramento River at Sherman Island and line most of the riverbanks, as well as the Sacramento River Deep Water Ship Channel and some connecting waterways north to Sacramento and beyond.
How long are the Delta Works?
The main attraction of the Delta Works is the Eastern Scheldt Storm Surge Barrier, a unique flood protection construction of 9 kilometers in length, that can shut off the entire Eastern Scheldt in 80 minutes. This ingenious system of 62 enormous sliding gates is meant to prevent a disastrous flood like the one in 1953.
Why were the Delta Works built?
The Delta Works were built to protect Zeeland’s dry land after the 1953 North Sea Flood or Watersnoodramp. It is the world’s biggest storm surge barrier, a unique structure well worth a visit! Visiting the Delta Works is a fantastic experience, especially with high winds and huge waves.
