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."

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
