Self-Closing Flood Door for private residence in Kruiningen, Netherlands

Monday, March 18th, 2019

This week we commissioned a Self-Closing Flood Door for a private residence in Kruiningen (Netherlands). The garage had already been flooded twice during heavy rainstorms. Rain- and surface-water which could not be evacuated by the overloaded public sewer system flowed into the lower lying garage, causing considerable damage.

Thanks to the SCFD this will be a thing of the past. In the event the SCFD’s drain is no longer able to evacuate rain- or surface-water the surplus water will flow into the underground basin which holds the floating flood-wall. The pressure of the upcoming water will push the barrier up and close off the entry to the garage.

The SCFD works autonomous, not requiring any external energy source nor human intervention. Barrier length 5 m, protective height 0.3 m.

8m long & 2m high Self-Closing Flood Barrier from AGGERES installed in underwater-film-studio

Monday, October 29th, 2018

29-10-2018 — In October AGGERES completed the installation of the 8m long and 2m high flood barrier in Europe’s largest underwater film-studio in Vilvoorde, near Brussels.  Eight 2.6m high elements were assembled on site and lifted into the underground holding bassin. The complete barrier weighs 1 Ton. The installation was done in 2 days.

When the studio is flooded the barrier will be activated by the pressure of the flood water, closing off the 8m wide entrance to the studio.  It is the first time we need to install an SCFB (Self-Closing Flood Barrier) to keep water inside a building instead of outside.

Later this year a test will be done in order to prepare the studio for the first recording scheduled for January 2019.


Activation of Self-Closing Flood Door in Paulatem !

Monday, May 28th, 2018


The 4m wide and 0,6m heigh autonomous flood barrier was installed in 2017 after the homeowners experienced two flood incidents. Water from the surrounding hills passed through their house on both occasions.

Yesterday’s (24 May) heavy rainfall filled the streets with flood water which activated the flood barrier, preventing the house from flooding. The homeowners were not present at the time. The neighbours made the photo.

Old Port of Spakenburg is finished before Christmas

Friday, December 23rd, 2016

A lot of hard work was done to finish the road and masonry around the old harbor before Christmas. From the 24th of December until the 8th of January the machines will be quiet for a while. The work will be paused during this period.

The Self Closing Flood Barrier around the historic port of the former fishing village is sunk into the ground. The second phase of the work will start after the Christmas holidays. The remaining 162 meters of the Self Closing Flood Barrier will be placed around the new port. Currently preparations are being made here for the placement of the Self Closing Flood Barrier. The quay wall will also be stabilized. From mid-February, a few streets will be raised to secure them against flood water.

Check out this video of the installation of the self closing flood barrier in the Old Port.

At the end of September the Self Closing Flood Doors (SCFD) were installed and tested at the museum. These are a preview of the world’s longest buoyant flood barrier that will soon be installed at the port. (more…)

Europe-wide flood losses to ‘increase four fold’ by 2050

Tuesday, March 4th, 2014

According to the most accurate model yet developed, flood damage losses across Europe are expected to increase four fold by 2050.

The scientists believe that the continent’s annual flood costs may be 2.5bn euros by the middle of the century.

Two-thirds of the projected increase in flood damage will be caused by human development, not climate change.

The study has been published in the journal Nature Climate Change.

One of the big problems for European flood disaster research has been that countries tend to do their risk assessments on their own, using different models and methodologies compared with their neighbours.

“This is not an accurate way of working,” said lead author Brenden Jongman from VU University in Amsterdam.

“We show that if you have very high flood risk in the UK there is also a very high risk in northern France, the Netherlands and some parts of Germany.”

Risk underestimated

Rather than looking at individual flood risks, the team decided to look at maximum water discharges in over 1,000 European river sub-basins, or parts of catchments.

They found that different rivers often reach dangerous levels at the same time, threatening large regions.

“If you don’t take into account these spatial co-relations then you highly underestimate the risk – there is a much higher risk than we actually think so far,” said Mr Jongman.

“We say the average annual losses are expected to increase by a factor of four between now and 2050.”

The researchers tested the model by looking at data from rivers between 2000 and 2012. From that information they estimated that annual flood losses across Europe would be 4.9bn euros per year. Reported annual losses were 4.2bn.

Using the same system, the team estimates that annual losses by 2050 across Europe would be 23.5bn euros.

Looking at the disastrous summer floods in Central Europe last year that cost 12bn euros in losses, the researchers estimate that the chances of an event like this happening in 2050 will have increased from once in 16 years to once in 10.

The scientists say that this is the first time they can look at the probability of total damages from floods across Europe.

And while climate change is an important factor, according to Brenden Jongman, it is not the critical element in their model.

“About two-thirds is caused by socio-economic growth,” he said.

“More people are living in flood-prone areas, [and] the income per capita is increasing in the dangerous areas around Europe.”

Muddy waters

Climate change cannot be dismissed and is likely to cause precipitation events to become more intense, and flood waters will likely be deeper and last longer.

While the increase in losses from floods is significant, the scientists believe that by investing in defences and mitigation, governments can limit the economic impact.

The amount of damages likely to be caused is far more than the costs of prevention, but Brenden Jongman says that political issues muddy the waters.

“The costs of these investments come up front, but the benefits of this flood protection might be in the future, not in the current government’s term.

“There may be no votes for them.”

BFDS becomes Aggéres

Thursday, January 30th, 2014

Logo_Aggeres_cut_40We are proud to announce that BFDS shall continue its activities with a new name: Aggéres.

The name change allows us to increase our ambitions;  We want to expand our territories beyond the borders of the Benelux, or even outside Europe.

Aggéres is short, recognizable and represents our desire to act.

The word “Aggeres” is Latin for “dykes”.
