Coastal erosion and coastal floods

Climate change impacts on dune erosion along the Dutch coast

The Dutch coast is eroding. A recent study shows that the volume of eroded dune sand increases linearly with sea level rise by little over 20 % per meter sea level rise.

Launched: coastal hazard assessment app

For developing countries the assessment of coastal hazards is often hampered by lack of data. Dutch researchers of Deltares developed an app to use global open assess data for these assessments.

How high will the seas rise?

Previous sea level rise projections may have underestimated the contribution of Greenland and Antarctic ice sheets. Recent studies lead to upward adjustment of estimated sea level rise in 2100.

Protecting Poland against future coastal floods is not that expensive

Impacts of future sea level rise and storm surges on the Polish coastal zone may be much less than previous studies indicated. And so are adaptation costs to strengthen coastal flood defences.

Lower wind speed and waves along the Irish coast this century

According to the latest research, wind extremes and storminess over the North Atlantic Ocean will decrease this century. As a result, future waves along the Irish coast will be somewhat lower as well.

Storm surge levels increase along Northern Europe’s coastline

Future trends in storm surge level changes along the European coastline show an increase for Northern Europe and small or no changes for Southern Europe.

Cretan beaches (Greece) highly vulnerable to sea level rise

High sea level rise may be catastrophic for the beaches of Crete. Strong erosion may require costly adaptation measures to ensure their long-term sustainability.

Sand Motor: Mother Nature helps the Dutch to protect their coast

The sea takes sand from the Dutch coast that is replenished by depositing sand on the beaches and in the offshore. The Dutch have found a more natural way to protect their coast: the Sand Motor.

Waves overtopping breakwaters increase Catalan ports’ vulnerability to sea level rise

One of the greatest impacts of sea level rise on seaports is related to wave overtopping. Sea level rise increases overtopping and potentially endangers boats and other assets.

Adaptation to sea level rise: where to protect and when to start?

Presented by Sally Brown (University of Southampton, UK) and Daniel Lincke (Global Climate Forum, Germany) at the Adaptation Futures Conference in Rotterdam, The Netherlands, May 2016

More water stored on land slowed down sea level rise in last decade

Over the last years, climate-driven changes such as large-scale floods have increased the volume of water on land. This increase slowed down sea level rise.

Future flood losses in major coastal cities

We shouldn’t just look at the consequences of a flood to conclude which deltas are most vulnerable. We should include flood probability, and thus flood protection infrastructure, as well.

Salt marshes will survive sea level rise

Sea level rise over the next decades is not an immediate, catastrophic threat to many marshes: marshes will survive in place under relatively fast rates of sea level rise

Benefits of protecting London from the sea

Options have been investigated for the future of protecting London from flooding from the sea. Economic analyses have shown that improving the existing flood defences

Delfland Sand Engine, from reactive to proactive coastal protection

Along the Holland coast an experiment is being carried out with a concentrated mega-nourishment with 20 million m3 of sand (the so-called Delfland Sand Engine).
