Oosterscheldekering facts for kids

One of the three movable barrier sections of the Oosterscheldekering

The Oosterscheldekering is a huge structure in the Netherlands. It acts as both a dam and a special storm surge barrier. This amazing barrier connects the islands of Schouwen-Duiveland and Noord-Beveland.

It is the biggest of 13 large projects called the Delta Works. These projects were built to keep the Netherlands safe. Their main job is to protect the country from big floods coming from the North Sea.

What is the Oosterscheldekering?

The Oosterscheldekering is a very long barrier, about 9 kilometers (5.6 miles) long. It is made up of several parts. Most of it is a solid dam, but a big section in the middle is different. This middle part has 65 giant steel gates. These gates can be opened or closed.

Why was it built?

The Netherlands is a low-lying country. Much of its land is below sea level. This means it is always at risk of flooding. In 1953, a terrible flood hit the country. It caused a lot of damage and many people lost their lives. After this disaster, the Dutch government decided to build the Delta Works. The Oosterscheldekering was the most important part of this plan.

Protecting the land

The main goal of the Oosterscheldekering is to protect the land. When there is a big storm or very high tides, the gates close. This stops the powerful North Sea water from rushing in. It keeps the towns and farms behind the barrier safe and dry.

Keeping the environment healthy

Building such a large barrier was a big challenge. Engineers wanted to protect the land but also save the natural environment. The Oosterscheldekering was designed to be open most of the time. This allows the tide to flow in and out of the Oosterschelde estuary. This tidal movement is important for the plants and animals that live there. It helps keep the water clean and healthy.

How does it work?

The Oosterscheldekering has 65 huge steel gates. Each gate is about 42 meters (138 feet) wide. They are held between concrete pillars. These pillars are very strong and heavy. They sit on the seabed.

Opening and closing the gates

Normally, the gates stay open. This allows the sea water to flow freely. Ships can pass through, and the tides can move. But when a storm surge is expected, the gates are lowered. This creates a solid wall against the sea. It takes about an hour for all the gates to close completely.

Advanced technology

The barrier uses advanced technology. Sensors constantly watch the sea levels and weather. If a storm surge is predicted, a central control room gets an alert. Engineers then decide when to close the gates. This system ensures the barrier is ready when needed.

Building this giant barrier

Building the Oosterscheldekering was a huge project. It took many years and a lot of effort. Construction started in 1976 and finished in 1986. Thousands of workers were involved.

Challenges during construction

One of the biggest challenges was placing the huge concrete pillars. These pillars weigh up to 18,000 tons each! Special ships were built just to carry and place them. The engineers had to work in strong currents and rough seas. It was a true test of human skill and determination.

A symbol of Dutch engineering

The Oosterscheldekering is often called the "Eighth Wonder of the World" by some. It shows how clever Dutch engineers are. It stands as a symbol of their fight against the sea. It protects millions of people and their homes.

Visiting the Oosterscheldekering

Today, the Oosterscheldekering is not just a flood barrier. It is also a popular place to visit. There is a special visitor center called Neeltje Jans. It is built on an artificial island near the barrier.

What can you do at Neeltje Jans?

At Neeltje Jans, you can learn all about the Delta Works. There are exhibits, films, and even a storm surge simulator. You can see the massive barrier up close. It is a great way to understand this incredible piece of engineering.

A safe and fun place

The Oosterscheldekering and Neeltje Jans show how humans can work with nature. They protect the land while trying to keep the environment healthy. It is a place where you can learn about history, engineering, and nature all at once.
