Climate Action

There is no doubt that the anthropogenic emissions of greenhouse gases are changing our living environment. Climate change is in our hands. We need to both work on limiting it as much as we can (mitigation), but we will also have to learn to adapt to new circumstances. TU Delft will harness its innovative powers to support the world-wide transition to non-fossil resources, and adaptation of the living environment to the consequences of global warming.

The problem is complex and urgent – but we have no other choice than to be optimistic and use all of our capacity to face the challenge, through our education programs and our research.

In the Climate Action research programme, we start from four themes we consider to be paramount for future Climate Action:

The TU Delft vision on Climate Action is deeply founded in preceding decades of university wide climate action research. The goal of the Climate action research programme is to build on current strengths and identify the areas where there is a need to strengthen our capacities to keep up our (inter)national reputation as climate action university.

Roots for riverbanks

Roots for riverbanks

The Netherlands has had an indissoluble relationship with water throughout history. Nowadays, 2400 km of waterways flowing through its veins use timber retaining walls along their banks. A more eco-friendly solution than brick or concrete but, still, not as sustainable as it could be. Civil Engineer Abhijith Kamath is researching an alternative method to use tree roots to strengthen waterways’ banks. Making Dutch channels greener in every way.

The breathing of dikes

The breathing of dikes

When looking at a dike, you wouldn’t be able to detect any motion in this robust structure. Though in fact there is. On a millimetre level, dikes expand and shrink in relation to the weather conditions. Ece Özer showed that observing this ‘breathing’ of dikes could help prevent catastrophic flooding events. She used this feature to create an innovative model based on satellite data to better detect weaknesses in a dike.

Not a band-aid but a feeder solution for our coasts

Not a band-aid but a feeder solution for our coasts

At the weekend Matthieu de Schipper likes to surf the waves but on weekdays he studies how they transport the sand along the coast and up and down beaches. ‘Sea level rise is a threat to coasts across the globe. I want to use the forces of nature to provide engineering solutions to this problem on a global scale’. At the Sand Motor project in the Netherlands De Schipper is training students to do the necessary fieldwork. In all weathers.

What the Wadden can teach us

What the Wadden can teach us

Intertidal zones are crucial for the protection of our coast and as stop-overs for migrating birds. But, increasingly, many of these sand and mudflats are disappearing permanently underneath the waves. Cynthia Maan investigated how by cooperating with nature and using a systems-based approach these precious resources can be saved.

Making dikes safer with a bass guitar

Making dikes safer with a bass guitar

Playing a bass guitar on top of a dike. It’s not something you see a TU Delft scientist do every day. Yet this is exactly how post-doc Juan Aguilar-López tested his experiment on dike monitoring with the use of fiber optic cables. A technology which could greatly improve dike safety in the future.

Greenland ice losses rising faster than expected

Greenland ice losses rising faster than expected

Greenland is losing ice seven times faster than in the 1990s and is tracking the IPCC’s high-end climate warming scenario, according to the Ice Sheet Mass Balance Inter-comparison Exercise (IMBIE) Team.

Weather alarm: chance of sudden death

Weather alarm: chance of sudden death

Rain radar, weather apps, satellite images and code yellow (weather warning code in NL): we are all fascinated by the weather. Nevertheless, even the experts know less about it all than we think, particularly when it comes to the weather at night and in cold areas. Bas van de Wiel wants to change that. He intends to use his ERC Consolidator Grant to give the underappreciated nights a bigger role in weather and climate models.

Continuously scanning the coast

Continuously scanning the coast

Hotel Atlantic in Kijkduin overlooks the North Sea. On its deserted roof a state of the art laser scanner is monitoring the beach every hour, 24/7. Sander Vos hopes the resulting data will provide insight into the restoration of the coast after a storm when part of the beach and fore dunes disappear into the sea. With the information provided by the scanner he and his TU Delft colleagues hope to become ‘coastal weathermen’ who will be able to predict exactly how the beach behaves after a storm.

Observing rain at street-level

Observing rain at street-level

Heavy showers sweep over cities, flooding streets and houses when urban drainage systems get overwhelmed. Ever-increasing pressures from climate change, population growth and changes in land use augment the risks of urban floods. We’re currently unable to predict accurately where and when flooding will occur. Forecasting is particularly tricky in densely populated cities, where rainfall observations are scarce, spatial variability in land-cover is high and flood response to rainfall is very fast. Researchers want to use radar and innovative ground sensors to observe rainfall and water levels more accurately and at higher density to improve the reliability of hydrological predictions . Marie-Claire ten Veldhuis is trying to gather this information in various projects. Her objective is to unravel the complexity of urban hydrological response, to be able to predict with greater accuracy when and where streets will flood.

Water lust and nuisance

Water lust and nuisance

Reliable tap water, proper waste water treatment, and dry feet. That’s what people in the Netherlands expect and are accustomed to. However, flooded homes, sewer overflows and impassable roads occur with increasing frequency. The Randstad conurbation has suffered from severe water issues in recent months for instance. The KNMI [Royal Netherlands Meteorological Institute] has predicted that the number of extreme showers will further increase in the 21st century due to global warming. The water infrastructure in our urban areas isn’t built to accommodate this, warns Professor Jules van Lier. He argues in favour of smarter solutions and a new paradigm for our Urban Water Infrastructure.
