The researchers expect that with the help of sensors it will be possible to monitor the stability of the protective walls, with measurements accurate to within one meter.
On the basis of the measurements, self-controlling software can then forecast dangerous situations before they happen, making it possible to implement measures in good time. The systems is currently being field-tested at Livedijk in Eemshaven, the Netherlands. Siemens Corporate Technology in Russia is developing the technology together with partners for the UrbanFlood research project funded by the European Commission, as the research magazine "Pictures of the Future" reports.
Worldwide there are 136 coastal cities with populations of over one million that rely on the protection of dikes and levees. The pressure on these protective barriers is mounting because the climate change tends to cause the sea level to rise, and gives us good reason to expect more frequent storms. Until now, levees have been secured by either building them higher or reinforcing them, but this only buys time. Another strategy is the analysis of levees to identify sections that are at risk of being breached. “Smart bulwarks” could even predict fractures or the impact of flooding before they have a chance to happen.
For the levee monitoring the Siemens experts are using software designed for the monitoring of production facilities and providing it with new parameters. They determine these parameters from measurements taken at test levees and dikes that were intentionally destroyed using different methods, including by eroding the back side of a dike. This is what led to the disaster of the North Sea flood of 1953, for instance. Another test involves simulating the effects of water that bores a tunnel through the levee, which was one of the reasons for the devastating flooding in New Orleans. Now the software in use at Livedijk is learning to correctly interpret the data measured by the sensors under real conditions. In order to incorporate seasonal influences such as precipitation and wind directions in the analysis, this field test is being conducted for two years.
Other project partners are working on alarm notification options, for example via all mobile phones or navigation devices registered in the region at risk. In a next step, the researchers will equip levee and dike sections in Amsterdam and Saint Petersburg with the early warning system and monitor critical changes by means of an Internet-based software platform. In the long term they want to connect all levees and dikes worldwide to this platform and thus create a global monitoring system.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
