Engineers Protect Coastlines From Threat Of Ocean Waves

31.03.2005


Engineers at the University of Liverpool are conducting research to reduce the threat posed to homes and property by ocean waves.



Approximately 10% of people in England live in areas at risk from flooding or coastal erosion. In the absence of man-made defences such as sea walls, the annual damage to property and roads in these areas would exceed £2 billion.

Terry Hedges, from the University’s Department of Civil Engineering has produced a computer model to assess volumes of water overtopping sea defences causing flooding, damage to property, roads and in some cases human fatality. His research will identify ways to minimise the amount of damage caused to coastal areas and measure the success of sea defences in protecting land and buildings.


Terry said: “The computer model will allow us to determine combinations of conditions which are dangerous to vehicles, pedestrians and buildings as well as the sea wall itself. We will be able to predict, for example, under what particular wave conditions roads may need to be closed or, in severe circumstances, if people need to be evacuated from nearby areas. It will also allow us to analyse how vulnerable our sea defences are. Our findings may result in sea walls being raised.

“Sea defences are, however, extremely expensive to construct. A kilometre of sea wall can cost up to £10 million and so it is important that we assess just how economical it is to build new defences, when it may be more cost effective to relocate a building or road.”

The team’s research will also involve constructing small-scale models of sea defences. The team can then create model weather conditions and measure the amount of wave overtopping to assess how the defences can be improved and how surrounding property can be protected.

Terry and his team, in collaboration with colleagues from Japan and Portugal, will use the results of the study to help flood protection agencies worldwide.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
