Hook of Holland is like the Sleeping Beauty (Delta, 16 of December, 2010).
On 21 December 2010 Ronald Waterman successfully defended his PhD-thesis. Professors Marcel Stive and Han Vrijling were his promotors. Dr. Waterman is well-known in the Netherlands and beyond for his plans for an integrated approach for our defence against water, making use of the 'building with nature' principle. He was one of the first to make plans for the expansion of the dunes and beaches along the Dutch coast using this principle. He wrote down his ideas in a standard reference work, 'Integrated Coastal Policy via Building with Nature.' He has now been awarded a PhD at Delft on the basis of parts of this book. Waterman’s vision of coastal policy in harmony with nature was first adopted in the Netherlands (for example, in the construction of the Second Maasvlakte), but has since been embraced worldwide. More information can be found in the December 21 edition of Cobouw and on Dr. Watermans own website.
Twenty million cubic metres of sand (Technisch Weekblad, 4th of December, 2010).
The works to create an artificial island in front of the Dutch coast will soon commence. This island wil function as a 'sand engine' that will feed the tidal currents and in this ay cause sedimentaion along the coast. Marcel Stive explains the priciple.
Presentation of the prof. Agema award (CUR Inzicht, December, 2010).
Prof. Vrijling presented the award on occasion of the Waterbouwdag 2010. The winner of this award Strukton, with the Busan immersed tunnel project.

Flood risks in the Netherlands (TV-show Helder- Teleac, 15th of November 2010).
Bas Jonkman has been invited to television talk show 'Helder' of Teleac broadcast company, to tell about the flood risks in the Netherlands and make suggestions how to reduce these risks. Attention was drawn to this topic by the recent high water levels of the Meuse river.
Does Neeltje Jans have the Power? (De Telegraaf, 10th of November, 2010)
Tjerk Zitman answers the question wether the Eastern Scheldt storm surge barrier can be used the generate electricity.
Unrealistic Dike Plan (Leeuwarder Courant, 4th of November, 2010).
Tjerk Zitman reflects on plans to reclaim a considerable part of the North Sea.
Life is beautiful (Vorm, November, 2010)
Jarit de Gijt carried out a PhD-research on the history of quay walls, and particularly on the development of their construction costs. He has been interviewed for Vorm, the PR-magazine of the Public Works Department of Rotterdam.
Do we learn enough from our failures? (CUR Inzicht, October, 2010)
Han Vrijling doubts if mankind learns enough from lessons in the past. Also in 2010 he was chairman of the 'Waterbouwdag' (Hydraulic Engineering Day).
Flood defence with buildings (De Ingenieur, 17th of September, 2010).
Bianca Stalenberg explains that the technical drawbacks of the combination of functions in a flood defence are relatively small.
Using buildings for flood protection (EurekAlert, 6th of September, 2010).
Bianca Stalenberg poses the question of whether it is possible to combine the urban functions of buildings with that of flood protection.
Living in a dike? (Radio Wereldomroep Nederland, 5th of September, 2010)
According to Bianca Stalenberg buildings, as well as parking garages, parks and roads can function as flood defences.
Car park as flood defence (Verkeer in Beeld, 3rd of September, 2010; and Architectenweb, 3rd of September 2010).
Buildings, car parks and roads could, alongside their 'regular' functions, have a role to play in protecting the rest of the city from flooding. According to researcher Bianca Stalenberg, this concept could be very useful for the Dutch cities along the River Rhine, for example.
Waterproofing urban life (Delta, 1st of September, 2010).
Increasing rainfall levels will force most Dutch riverside cities to augment their flood defences. Why not improve the urban quality at the same time, asks PhD student Bianca Stalenberg.
Protected, but not yet safe (Reformatorisch Dagblad, 1st of September, 2010).
Hurricane Katrina caused severe damage in New Orleans, on 29 August 2005. Failure of flood defences caused floodings. Now, after vife years, the new coastal defence has been almost completed, but it still is not safe enough, according to Han Vrijling.
The rise of the flexible harbour (Financieel Dagblad, 21st of August, 2010).
Han Ligteringen explains that harbour concepts are not static anymore. They are constantly adapted to new needs an technological progress.
Erosion mechanism Piping (Infostroom, August, 2010).
Han Vrijling presented the results of a recent study into the piping failure mechanism. The complete report can be found at www.ENWinfo.nl.
Elsevier Technology debate (Elsevier, 24th of April, 2010; and Delta, 29 of April, 2010).
Professor Han Vrijling and Simon Rozendaal, Science Editor at Elsevier, discussed the policy about how to cope with the rising water in the Netherlands. Is dike reinforcement really a bad choice? The debate was held in The Hague, on 26 April 2010 from 16:00 to 18:30 h.
Sandbank creates ideal surf wave in Scheveningen (NRC newspaper, 11th of March, 2010).
Regular beach suppletions have a negative effect on waves for surfing. The design for the Scheveningen beach profile takes the fun of surfers into account. Erik van Ettinger (a TU Delft MSc), and PhD-students Sierd de Vries and Matthieu de Schipper worked on the design of artificial reefs to generate nice surfer waves.
The Banished Water (Delft Outlook, 2010).
The Delta Commission issued its final report in 1960. At that time, construction of the Delta Works was already well under way. Nearly five decades later, in 2008, the “second Delta Commission” issued its report. There was a world of difference between these documents. Professor Han Vrijling gives comments on the new plans.
Adventure in the River (Delta, 6th January 2010).
Kees Sloff, lecturer and researcher river morphology, performed measurements in the Colorado river, climbed craters on Java to study vulcanic rivers and did research to gain insight in the river bed fall in Vietnam. His work is a big adventure.
Professor Vrijling demonstrates negligence by the Corps of Engineers in New Orleans (4th of January, 2010).
A testimony of professor Han Vrijling of TU-Delft has convinced an American judge to find the Corps of Engineers, the genius of the American army, guilty of causing the floods in a part of New Orleans during Katrina in 2005. According to the judge, these floods are the consequence of negligence by the Corps.
Amsterdam metroline will be completed (NRVB, 2009).
Prof. Han Vrijling looks back on his activities as member of the advisory commission on the Amsterdam North-South metro line.
Creative with Water (Integraal 2009-4, in Dutch).
Civil structures do not always have a high aesthetical value. The "Climate Adaptation Lab" wants to change this image by stimulating the cooperation of graduate studenst Civil Engineering and Architecture. Some of our students have been interviewed for this article.
Scaled Water Power (Integraal, 2009-4 and abridged in: Delta, 13 January 2010).
The Laboratory of Fluidmechancis, which is part of our Department of Hydraulic Engineering, has to be reduced due to shortage of funding. Head of the Laboratory, prof. Wim Uijttewaal hopes that cooperation with Deltares (former Delft Hydraulics) will help.
