![]() “The further optimisation of the design rules in order to maximise not only protection against flooding but also biodiversity is an important challenge that we are addressing in our current field research. Tjeerd Bouma, a researcher with NIOZ, highlights how this research can contribute to additional challenges. There is already a delta ofSolvay waste in the lake outside of the bermed areas of Waste bed B, suggesting that inlake disposal had been occurring before this. Highest artificial waves in the world The Delta Flume is 300 metres long, 5 metres wide and 9.5 metres deep. ![]() The 9,5 m deep trough with the 10 m high wave board - in blue - at the end. ![]() For example, we can now make much better calculations of how long a forest in front of a dike should be to provide the desired wave attenuation.” The Delta Flume, to be inaugurated on 5 October, is a 300-meter-long water-filled trough that is 9.5 meters high and 5 meters wide. The Delta Flume is constructed in such a way that it allows researchers to build realistic 1:1 scale models of 85 percent of Dutch coastal defences. This study is an important step towards establishing design rules for innovative approaches. The Delta Flume is a wave flume that is unique because of its dimensions: it is 240 metres long, 5 metres wide and has a depth of 7 to 9,5 metres. Particularly in the context of climate change and sea level rise, we have to learn to work better with the natural systems that are already in place. Van Wesenbeeck: ‘You can’t always just go around building dikes. Combinations of natural landscapes and hard defences are promising, according to the researchers, while they can make many places in the world a lot safer. In the Afsluitdijk project the X-BlocPlus is used under the name Levvel-bloc.The aim of the study is to establish a clear picture of the functions of natural systems to design better solutions for different coastlines and river areas around the world. Storage capacity 9.2 million liter water. This DeltaFlume is based at Deltares, at our campus in Del. This single orientation allows a much easier and quicker placement of the 6,5 ton armour unit. The new Delta Flume Other aspects of the new Delta Flume Soft soil underneath flume: 800 foundation piles (9 km in total). Testing dunes and dikes, and innovative protection measures. The advantages being that the blocks all have the same orientation and the interlocking between the units is not variable. The Delta Flume is 300 metres long, 5 metres wide and 9.5 metres deep. ![]() DMC designed their latest X-Bloc version in a shape that can be tilted in a regular pattern. The 9,5 m deep trough with the 10 m high wave board - in blue - at the end. The maximum wave heights that can be generated are about Hs2.2m with maximum individual wave heights in the. Normally, armour blocks, including the X-Bloc, are placed irregularly by dumping them on the slope of a breakwater. The new Delta Flume has a length of about 300m, a width of 5m and a height of 9.5m. The original Xbloc has been applied worldwide since 2004 and is used to protect breakwaters and shores against waves.ĭMC developed a more advanced version, the X-BlocPlus which has the same wave breaking capacity with less concrete. The Levvel-bloc is the latest version of the X-Bloc armour unit as designed by Delta Marine Consultants (DMC), a subsidiary of BAM Infrastructure. This DeltaFlume is based at Deltares, at our campus in Delft (The. Testing dunes and dikes, and innovative protection measures. The initial beach slope of combination of 1/10 and 1/20 is exposed to regular waves and cnoidal waves respectively. 4.4K 1.1M views 8 years ago Generating waves with our DeltaFlume. Deltares' research facilities for water and soil research are unique in many ways. The same goes for the innovative GeoCentrifuge in which we reduce processes in the subsurface that in reality take years to hours, necessary to build a road or tunnel. Image of the Levvel-blocs (at sea level) as a neatly staged layer of amour units to protect the Afsluitdijk against waves. Laboratory experiments are performed to explore the response rule of a sandy beach profile under plunging wave on a non-uniform sediment-bed slope. The 300-metre-long Delta flume where we can simulate waves of more than 4.5 metres high is world-famous.
