The incomprehensible fear for geotubes (article in Dutch, Cobouw, 19 december 2006).
There should be a large scale test with geocontainers and geotubes in a water defense structure. They're cheap, environmentally friendly and recently two CUR publications appeared about these elements. ir. Jarit de Gijt was one of the engineers being intensely involved with this publication.
Government should invest more seriously in flood defense (article in Dutch, Contact magazine voor civiele techniek en geowetenschappen december 2006).
Interview with Prof. Han Vrijling, the budget to maintain the flood defense systems is to low.
Payment of dikes (article in Dutch, NRC Handelsblad, 16 December 2006).
The State of the Netherlands should decide to leave the payment of dikes to the water boards. These boards should levy more taxes. This is what prof. Han Vrijling and prof. Marcel Stive (a.o.) advised.
Evacuation not very effective in case of flooding (article in Dutch, December 2006).
A possible flooding of the southern part of the Randstad in the Netherlands will result in several thousands of casualties. An evacuation of the area will not do much good. Our PhD-researcher Bas Jonkman worked on an advanced model to simulate the consequences of an evacuation. National press published articles on this topic, see for instance: De Volkskrant, Elsevier, De Telegraaf and NRC Handelsblad.
Rocking on invisible waves (article in Dutch).
Waves with a length of several kilometers plague sea ports all over the world. This causes severe problems for moored ships. Wim van der Molen studied this phenomenon and wrote a doctoral dissertation "Behaviour of moored ships in harbours'.
The Netherlands submerge (article in Dutch).
The Netherlands are not safe for floodings. The Dutch Society of Engineers wrote a letter to the ministery of transport and communications. Prof. Vijling, prof. Stive and prof. De Vriend (a.o.) signed this letter to express their concern. (11 October 2006). Algemeen Dagblad of 18 October published an article "Many dikes in bad condition" on this same letter (in Dutch).
Still hungry for sand (article in Dutch, 28 September 2008 ).
Sand from the Dutch coasts of North Holland and the island of Texel still moves into the Wadden Sea. Edwin Elias found out that this sea did not decrease its eagerness for sand from its surroundings, as was assumed until now.
Surviving in the Delta (Land en Water, October 2006).
Is it a coincidence that the 'Waterbouwdag 2006' (hydraulic engineering day 2006) has been preceded by a major flooding? The event rises the question if the Netherlands are adequately protected. Han Vrijling gives an introduction on occasion of the Waterbouwdag 2006.
Growing breaches (article in Dutch).
As long as dikes exist, breaches will occur. However, knowledge about breach growth only recently increased thanks to the research of Yonghui Zhu. (21 September 2006)
Students from Delft University design surf walhalla (article in Dutch, 21 September 2006). Two of our Hydraulic Engineering students, Matthieu de Schipper and Sierd de Vries study the design of a swimming pool with a wave machine for the benefit of surfers. Delta, the Delft University weekly magazine, published an article about their work.
It's cheaper to go Dutch (article in English).
"The Netherlands is expert at keeping itself dry. So why aren't U.S. bureaucrats seeking more of its help rebuilding the levees?" Read the answer in the Newsweek article, for which prof. Han Vrijling, head of our department was interviewed.
Insurance against floods (audio stream in Dutch). On Monday 15 august 2006, prof. Han Vrijling commented on plans of Dutch minister De Vries to make it possible for citizens and companies to take insurance policies against floodings. On the Dutch public radio station Radio 1, mr. Vrijling discussed the possibility that in this way the authorities could escape feeling responsible for the consequences of overdue maintenance.
The wave juicer (article in Dutch).
On Sunday 6 August 2006 students and members of Delft University squeezed oranges on the beach of Scheveningen. A juicer was connected to a device that generated electricity out of waves. This event was organised to demonstrate the diversity of technology fields that are engaged with sustainable energy and to bring civil engineering under attention of the Dutch people.
