MVRDV wins competition for landmark public installation in Den Helder with ‘infinite loop’ design
This stunning Seasaw concrete sea defensewill rock back and forth with the tide along the Dutch seashore. MVRDV recently won a competition to design a unique permanent art installation for the scenic coastal Dutch city of Den Helder.
The design, which will rise on a historic dyke north of Amsterdam, is a curvilinear observation platform that twists into an infinite loop perched several feet over the sea. Read More
Arcadis is in charge of actions to be taken to strengthen Manhattan’s coastline. Over four kilometers will be strengthened by building watercourses, dams and a better drainage system.
The Manhattan project is the first part of a coastal defense system. In order to win the project, Arcadis participated in the contest ‘Rebuild by design’. The contest was canceled after Hurricane Sandy, who caused tens of billions of dollars five years ago. Read More

ECOncrete® supplies a range of modular esthetic sea wall elements, which functionally integrate into coastal infrastructure.
Our waterfront needs to protect us from het rising sea level. Good news: The number of innovative options for restoring ecology along the urban waterfront seems to be increasing by the minute.
Since land in urban areas is often unavailable or difficult to restore to pre-settlement times, floating wetlands (FWs), an ecologically engineered technology, represent an effort to mimick the wetlands that existed long ago.
FWs hold the promise of returning ecological services like pollutant uptake and transformation, water quality improvement, wave attenuation, habitat, and aesthetic beautification.
Flood risk maps like this one from NOAA, are not glamorous or technologically exciting things. They have done their work for many years and, provided that they are up to date, are an effective way of communicating a generalized level of risk.
XBeach-G model helps to protect gravel coasts like the Chesil Beach, as seen at Chesil Cove, Dorset (England)
XBeach-G model helps to protect gravel coasts in the United Kingdom against storms and rising sea levels.
Gravel beaches are widely considered as an effective and sustainable form of coastal defense. Until now, there has been little research done, understanding the mechanisms leading to their failure during storms.
That’s why coastal managers have very limited guidance when estimating the potential for flooding on gravel coasts. Read More
Before and after: beach nourishment using dredged sediment from the deepening of the navigation channel in Poole Harbor(UK)
Dredging and disposal of sediment poses some unique challenges in the ecologically protected Poole Harbor (UK).
This multi-objective project provides a win-win solution: using dredged material beneficially solving a river bank erosion problem helping to restore 7,000m3 of reed-bed, a declining, nationally important habitat.
This Block-It wall comes up with one push on the button. The whole area behind is protected against high floods. This concrete wall is provided with an intelligent independent operating system.
Every knows the life expectancy of high tech concrete substance is more than 100 years! And … this wall is also suitable in areas with flood threats as ports and along coastlines.
Do you want 1 meter high? Fine. If the area needs 5 or even 10 meters high, that’s no problem. This wall is perfect for river sites in urban areas. And when it’s down: it’s fully integrated in the road. Read More
When a flooding is imminent, well known methods used for protection are dated. Sand bags and systems that require water pumps, air compression, stones or other equipment to create a barrier, are a hassle and too time-consuming.
Take a look at the Tube Barrier. This one is fast, light weighted, flexible and easy to store! Take a look at the video. Read More
The Hydroguard protects your house, office or large building against flooding
They started out at the 17th of September and as for today, the 30th, they have eighteen days to go at the UK crowdfunding platform Indiegogo: The HydroGuard, “the ultimate flood defence barrier” for private homes and bigger buildings.
So, just before the middle of their acquisition term at this rather popular platform, how are they doing? Let’s see –
How much do they need? 50 thousand British Pound (€ 64,330 or $ 81,065)
In 1995 250,000 people had to be evacuated in Holland due to floods. In response the Dutch gave up on dykes and went for high tech flood defences to protect their cities and controlled retreat in the countryside. Dredging didn’t figure too high in the plan. Read More
