Dutch recipe for climate change. The high water is stopped by sand

Climate warming is complicating the fight against the danger of floods in the Netherlands, but locals are enjoying a new method that turns sand into their allies.

Constructions using sand are often considered unstable, but The Netherlands claims to have developed a technique that allows this material used to strengthen one of the most important dikes in the country. Roughly a third of the area of ​​the Netherlands lies below sea level.

The project, which started in 2017, is to spill out sand against the dam to create a kind of natural barrier serving to flood prevention. The Dutch want to export their idea because the rise of water caused by global warming is threatening more and more countries.

The Houtribdijk dam in question is one of the main means defense against floods in the Netherlands since it was more than 40 years ago built. Its construction began in 1963, ten years after you did large-scale floods in the Netherlands have claimed about 1,800 people lives.

The Houtribdijk dam was built to break the incoming waves from Lake Ijsselmeer in the north of the country, which allows you to regulate the level tide. Its construction led to the creation of the second Lake Markermeer.

However, in recent years, experts have concluded that the dam is long 25 kilometers no longer meet safety standards and that you urgently requires reinforcement.

“We are facing a dilemma. There are no rocks in the Netherlands. It would be necessary to import stone from countries like Norway at a high cost, ”he said Professor Stefan Aarninkhof from the University of Technology to AFP v Delft.

The sand is pumped under a thick layer of mud at the bottom of Lake Markermeer and from both sides of the dam is brought in a specific way that they have developed scientists. Nature will then take care of the rest: the sand eventually serves as barrier against rising water, say the initiators of the project. To the dam to by the middle of next year it will bring in more than ten million cubic meters meters of sand.

According to the Dutch government, strengthening the sand dam is a world premiere. “The dam will then be able to withstand the strong storm that is coming on average once every 10,000 years, “says the government. She’s on the project participates together with private companies and research institutes.

The Dutch hope to sell the idea abroad to help other countries in the fight against climate change.

“We learned a few rules on how to work in the lake and build together with nature, ”says EcoShape spokesman Fokko van der Great. The consortium brings together the parties involved in the project. “It simply came to our notice then buildings in harmony with nature can be applied in the world wherever there is protection against water problems, “he adds.
