Virtual floods modelled inside computers are an increasingly useful means for authorities to prepare for genuine river surges. With flooding classed as the worlds most costly natural hazard, an ESA project has assessed using satellite imagery to improve flood simulation models.
Flood control and management represents a major challenge for water authorities, and as the global incidence of flooding increases, it has also become a subject of concern for the global insurance industry.
The US Geological Survey estimates that flooding is the worlds most costly type of natural disaster, costing €170 billion ($200 billion) between 1991 and 1995. Last years European floods alone are reported to have caused more than €7 billion of damage.
Like everything linked to the weather, floods are difficult to predict – a few days of steady rainfall might be sufficient for a river to burst its banks.

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.

Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.
"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...
A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.
Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
