University of Twente writes:
In the future, due to climate change and corresponding extremely high water levels, rivers in the Netherlands will be more likely to break their banks. This was the conclusion reached by Dutch researcher Suleyman Naqshband [...]. River dunes in the major rivers of the Netherlands tend to persist and not flatten out, thereby increasing the risk of flooding.
River dunes in this case is the somewhat unfortunate name for sand structures at the bottom of the river. Apparently they are quite common in Dutch rivers. The university adds:
These river dunes can reach large sizes, growing to as much as one third of the total water depth. This restricts the flow of water, causing water levels in the area of river dunes to be much higher than in sections of the river in which they are absent. River dunes are also dynamic, growing rapidly in just a few days then flattening out or even disappearing completely at extremely high flow rates.

‘Tractor girl’ Manon Ossevoort, a 38-year-old Dutch actress and adventurer, has arrived at the South Pole at 10:30 p.m. EST on 8 December 2014 after a 17-day, 2,500-kilometre journey across Antarctica in a red Massey Ferguson MF 5610 tractor.
Ossevoort had already driven a tractor 38,000 km from her home in the Netherlands across Europe and Africa in 2005, when she had missed the boat due to transport her to Antarctica. At the time Ossevoort returned home, wrote a book, and waited for the opportunity to finish the final leg of her journey.
The journey was achieved with the help of a mother and daughter team from Iqaluit, Nunavut, Canada, Matty McNair and Sarah McNair-Landry as well as a mechanic, two truck drivers and a creative director. The first mechanised trip to the pole was done in 1958 by Sir Edmund Hilary using Ferguson TE20 tractors.
In 2008 Bernice Notenboom reached the South Pole on skis, becoming the first Dutch woman to do so.

The A15 motorway south of Rotterdam is not a nice road to cross if you are a pedestrian or cyclist. Eight lanes of terrifying motorized menace are bordered by a double railway on one side and another road on the other.
To help you escape the city without having to play a game of humanFrogger, this bridge, which appears to have come straight from the set of a science fiction film, was built earlier this month. All 190 metres of it connect the city of Rotterdam to the nature preserve of Rhoon.
The bridge, called ‘De Groene Verbinding’ (‘The Green Connection’) was designed by Marc Verheijen, an architect employed by the public works department of Rotterdam. If you want more photos and information, Mark Wagenbuur has an extensive write-up including pictures and videos.
The photo above comes from the Province of South Holland who have also dedicated a page to the bridge.

Back in 2010 the world famous Anne Frank chestnut tree had blown over and broke. In an effort to save something of this tree mentioned in Anne Frank’s diary, branches were take in order to try and grow saplings.
Today, one of the saplings is big enough to be planted, and its prestigious destination will be the Capitol in Washington, DC, the seat of the United States Congress. This is not the first time the United States has planted saplings from the Anne Frank tree; in fact 11 have already been planted throughout the country.
The sapling will be planted on the Capitol’s west front lawn on April 30.

Plant-e , founded by David Strik and Marjolein Helder in 2009, is a spin-off company of the Environmental Technology of Wageningen University. After obtaining her PhD in November 2012 Helder became the CEO of Plant-e, while Strik works as an assistant professor at the university, supporting Plant-e’s research and development one day a week.
On March 12, coinciding with Dutch Arbour Day (‘Nationale Boomfeestdag’), Plant-e signed a deal with the Dutch government to build a plant-driven power plant. The plants will be grown on the Hembrug military terrain in Zaandam, North Holland and will be used for outdoor lighting and charging mobile phones.
Thanks to photosynthesis, a bioenergetic process used by plants to convert light into energy, plants create organic material. The roots of these plants contain bacteria that breaks down organic material, giving off electrons. Plant-e has created technology that captures these electrons as carbon electrons, which can be used directly as electricity.
Just this month we told you about a table that uses plant energy to charge mobile phones.

Considering how much land the Dutch have reclaimed over the years, giving an island back to nature is definitely newsworthy.
Back in 2012 we told you about how two lucky people could apply as a tandem to watch birds on the island of Rottumeroog as a summer job. Unfortunately, last December, a storm apparently weakened the dunes around the house, which has now been destroyed, leaving the island uninhabited.
Only last month the only trail on Rottumeroog was officially named ‘Jan Brandspad’. The island’s municipality, Eemsmond, had to give the trail a name as required by law. There were even plans to put up a street sign.”

Amsterdam-based artist Lotte Geeven has recorded the sound the Earth makes from the ‘deepest hole in the world’, which is apparently nine kilometres deep, near the Czech border. Seismologists, geophysicists and engineers helped her with this project, resulting in a series of sound installations.
It reminds me of some classic industrial music, probably Lustmord or a loop of 1980s Zoviet France. It’s soothing but eerie at the same time.

In Yerseke, Zeeland, a small Dutch fishing village, Hannah van den Boomgaard crunched on something hard while eating oysters only to realise she had found a twin pearl, two pearls grown together, which look like a big tooth or even a good luck doll, as Van den Boomgaard said herself.
Earlier this year in Arnhem a chef found a pearl in an oyster, which was rare, but the double pearl is of course, even more rare.
Oyster make pearls around grands of sand or other irritants as self-protection using nacre, the same substance its shell is made of, but then usually round. Cultured pearls are made by putting irritants in the oyster so that they will produce a pearl around it.

If you look at the places from where the rose-ringed parakeet originates, you’ll note that these are some of the hottest spots on the planet. So it comes as a bit of a surprise that large groups of these birds thrive in much colder climes.
Certainly the gardens behind my apartment aren’t part of the tropics, at least not last time I checked, which is when I took this photo.
Wikipedia claims the four largest cities in the country—Amsterdam, Rotterdam, Utrecht and especially The Hague—are home to about 10,000 of these parakeets. It is assumed the birds are the descendants of parakeets once kept as pets. The male bird sports a red ring around its neck, hence the name rose-ringed parakeet.
A statue of philosopher Baruch Spinoza unveiled in Amsterdam in 2008 contains images of roses, rose-ringed parakeets and sparrows, representing Spinoza himself, immigrants and native citizens.
Other cities north of the Mediterranean with large rose-ringed parakeet populations are Brussels and London.

At hetregentbijnanooit.nl (it almost never rains dot nl) avid cyclist Gerard Poels from Grave near Nijmegen keeps track of how many of his bicycle commutes get rained on.
In the past five years it rained during an average of 9.4% of Poels’ rides, each of which took 40 minutes each way. Poels counts every little shower even if it rains for just a few minutes. He claims it happens only 4 or 5 times each year that it rains during the entire ride. During those five years Poels rode his bike to and from work 1,482 times.
Poels set up his site to counter the excuse “I am not going to take the bike to work because it always rains [in the Netherlands]“.
Eamelje.net points out that Peter Siegmund of the Dutch meteorological office (KNMI) calculated the probability that you will get wet if you stay outdoors (PDF). If you stay outdoors for an hour in the Netherlands, there is a 12% chance that you will get rained on. If you stay out for four hours, that probability increases to about 25%, and you will have to stay out for at least a fortnight to be absolutely sure to get wet. Siegmund adds that fans of camping are most likely to stay dry in June. Even then the probability of rain during a single week is still 91%.
