YouTuber Tom Scott visited the Waterloopbos in Marknesse in the Noordoostpolder and had a little chat with Leo van Rijn, a specialist in modelling the flow of watercourses.
As wiki says: “The Waterloopbos [literally ‘Watercourse Forest’] was the property of Delft Hydraulics […]. In 35 large scale models of sea arms and harbours, such as the Deltaworks and the harbour of Lagos, tests were performed in order to learn how to predict the way large hydraulic systems influence the course of water.”
The laboratory closed in 1995 and the forest is now owned by Natuurmonumenten and is open to visitors from sunrise to sunset (Dutch). It is part of the Voorsterbos, the oldest forest in Flevoland, a province that was entirely reclaimed from the water.

For many of us who have driven the 32-kilometre-long Afsluitdijk from North Holland and Friesland (or the other way around), it’s a short cut with a great view of the water and sheep. However, historically, the Afsluitdijk is a key part of the country’s world-famous sea defences, as well as a major Dutch accomplishment.
Yesterday, Dutch artists unveiled a design and light show to highlight this feat of engineering, called ‘Icoon Afsluitdijk’ (‘Icon Afsluitdijk’), which shines at night “to enhance and safeguard the dyke’s rich heritage and anchor its position in the world as a Dutch water engineering and design icon,” according to its creators.
The project consists of a number of art installations, of which the last one is called ‘Gates of Light’, created by Daan Roosegaarde and his team. They applied a reflective layer to the Afsluitdijk’s 60 floodgates, which allows the concrete gates to brightly light up at night in the retro style of the 1930s, when the dyke was first built by hand.
The Dutch have lit other important landmarks up, such as the Kinderdijk, UNESCO World Heritage Site, with colours matching the Dutch flag.
