Scientists have compiled a new database of coastal flooding in the UK over the last 100 years, which they hope will provide crucial information to help prevent future flooding events.
'SurgeWatch' contains information about 96 large storms taken from tide gauge records, which record sea levels back to 1915. It shows the highest sea levels the storms produced and a description of the coastal flooding that occurred during each event.
The database, which is described in the journal Scientific Data, has been produced by a team of researchers, led by the University of Southampton and including scientists from the National Oceanography Centre and the British Oceanographic Data Centre.
Lead author Dr Ivan Haigh, Lecturer in Coastal Oceanography at the University of Southampton, says: "The winter of 2013/14 saw some of the UK's most extreme sea levels, waves and coastal flooding for several decades. During this period storms repeatedly subjected large areas of our coast to enormous stress and damage, reminding us of the real and ever-present risks and challenges facing coastal communities today."
Professor Kevin Horsburgh, Head of Marine Physics and Ocean Climate at the National Oceanography Centre, says: "This new database allows us to improve our understanding of the statistics of extreme sea levels around the UK. Coastal flooding remains a threat to life and to economic and environmental assets. Even if there is no future change in European storminess, the slow rise in mean sea level will increase the number of times that defence thresholds are exceeded. This database is a useful tool for coastal engineers and planners who are concerned with changes to extreme sea levels."
SurgeWatch is free and accessible to a range of users, including scientists, coastal engineers, managers and planners. The team aim to expand and update the database and are appealing for the help of the general public.
Dr Matthew Wadey, a postdoctoral researcher in Ocean and Earth Science at the University of Southampton, adds: "Do you have any photographs of coastal flooding from recent or past events, which you are willing to share with us? We would like to compile and investigate these in order to improve our understanding of exactly which areas were flooded and to what water depth. Photos can be easily uploaded to our website."
Prompted by people asking "Just how unusual was the 2013/14 season?" the researchers spent over 18 months compiling records of high sea level events and coastal flooding going back 100 years. Using meteorological data, they were able to identify the large storms that produced these high sea levels, investigate the weather conditions and track of each storm. They then spent many thousands of hours reading old reports, books, news articles, blogs and websites, to estimate the extent and scale of the coastal flooding.
Elizabeth Bradshaw, data scientist at the British Oceanographic Data Centre, says: "Was the 2013/14 season unusual? Yes, very much so. Seven out of the 96 events in the 100-year database occurred during the 2013-14 storm surge season. Two of the events (5 and 6 December 2013 and 3 January 2014) are ranked in the top ten, in terms of height of sea levels. Both of these events also rank highly in terms of spatial footprints, i.e. they impacted very large stretches of the UK coast."
Robert Nicholls, Professor of Coastal Engineering at the University of Southampton, adds: "The fact that the damage was so limited during the December 2013 and January 2014 storms, compared to the tragedy of January 1953, during which 307 people were killed along the UK's North Sea coast, is thanks to significant government investment in coastal defences, flood forecasting and sea level monitoring. It is therefore vital we continue to invest in defences, forecasting and monitoring and continue to update this new database."

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
