Flood risk underestimated, particularly in the tropics

29 June 2021

“To assess flood risks, we need to know the exact land elevation,” explains Al Hooijer, a researcher at Deltares and the National University of Singapore, and first author of the paper ‘Global LiDAR land elevation…

More people exposed to low-probability coastal flooding than previously expected

29 June 2021

Using their novel dataset, the researchers found that 192 million people are exposed to a 1-in-1000 year flood, of which 60% can be attributed to tropical cyclones – also called hurricanes or typhoons – alone….

COASTAR project publishes potential of the subsurface in The Netherlands to prepare for drought

28 June 2021

Fortunately, the early months of 2021 were wet and groundwater levels are rising again. In the future, wet and dry years will continue to alternate so it is essential that we use the available fresh…

New maps of foundation risk at neighbourhood level in the Climate Impact Atlas

28 June 2021

The risk of damage depends on the exposure, the probability that a property in a local area has been built on susceptible foundations, and vulnerability, the probability that a property on susceptible foundations will actually…

Deltares helps Seychelles with National Climate Plan

24 June 2021

The World Bank commissioned Deltares to help the Seychelles during the drafting of their national determined contribution to the Paris Climate Agreement. In addition to the chapter on climate adaptation, we helped with a chapter…

An acceleration of coastal overtopping around the world

23 June 2021

By combining satellite data and digital models, the researchers have shown that coastal overtopping, and consequently the risk of flooding, is set to further accelerate over the 21st century, by up to 50-fold under a…

Updated land subsidence maps show the effects of climate change and water level management

23 June 2021

The maps (in Dutch only) show the extent to which land in the Netherlands will subside in two clearly distinct futures.  “The two extreme scenarios make clear the probable bandwidth of land subsidence at the…

Coastal retreat as a serious option to adapt to sea-level rise

17 June 2021

Shrinking solution space The effectiveness and feasibility of the adaptation options that are currently used is expected to decrease progressively with sustained and accelerating sea-level rise, compounded with other climate-related changes like intensification of extreme…

Floods and droughts: an EPIC response to these hazards in the era of climate change

17 June 2021

Hazards don’t need to become disasters Floods and droughts are some of the most tangible – and devastating – consequences of the climate crisis. They increasingly affect communities across the planet. The toll in human…

Strategic Agenda ’22-25

10 June 2021

Focusing on the future comes with the territory of water management and  subsurface. Climate change irrevocably leads to long-term changes. Accelerate the fight against climate change and accelerate the adaptation of our living environment. Focusing…
