We have designed this website to inform and facilitate current students, prospective students, alumni, scientists, practitioners, media, colleagues and our staff on our field of focus. Our homepage offers access to section-related information that we control and update, to our direct "Delft" environment and it offers a login to our staff.

How coastal seas help the ocean absorb carbon dioxide from the atmosphere
The biologically productive North Sea impacts the global climate through exchange of carbon and nutrients with the Atlantic Ocean. A Dutch consortium of scientists will investigate how big this role of the North Sea really is. Under the leadership of the Royal Netherlands Institute for Sea Research (NIOZ), conduct a combination of field studies and computer model simulations will be conducted over the next four years to address this question. Models will be used to determine future effects of environmental and climate change on the North Sea, Atlantic Ocean and ultimately Earth’s climate. TU Delft's Peter Herman and Bram van Prooijen (Civil Engineering & Geoscience) are involved in the research.

PATH2ZERO: transition to zero-emission inland shipping
NWO has awarded a research grant to a consortium led by Alex Kirched for the project PATH2ZERO: PAving THe way towards Zero-Emission and RObust inland shipping. PATH2ZERO aims to contribute to the transition to zero-emission inland shipping in cooperation with the inland shipping sector. The consortium of researchers, companies and social organisations will start developing sustainable business models and action perspectives.

TU Delft researchers: sea level rise along Dutch coastline accelerating
De zeespiegelstijging langs de Nederlandse kust is aan het versnellen. Dat melden wetenschappers van de TU Delft in een nieuwe studie. Uit een uitgebreide analyse van de metingen van acht getijdestations langs de Nederlandse kust (onder meer die van Maassluis, Delfzijl en Vlissingen) blijkt dat de gemiddelde zeespiegelstijging – sinds midden jaren negentig – 2.7 ± 0.4* millimeter per jaar is. In vergelijking tot de zeventig jaar daarvoor is dat een significante stijging van 1.0 ± 0.5 mm/jaar.
Sweet solutions to a salty problem
Some sixty kilometres, all the way up to Gouda, that’s how far inland the Rotterdam Waterway has been carrying salty North Sea water over the last few years. Salt intrusion in Dutch rivers is a growing problem for the country’s drinking water supply and agriculture, not only in the Dutch delta but in deltas worldwide. Julie Pietrzak is trying to find better ways of predicting and combating the problem.
Counting grains of sand to understand coastal dunes
The Dutch coastline is continually changing. Coastal engineer Sierd de Vries is using small ventilators, home-made wind tunnels, drones, jet skis and laser scanners to gain an insight into the development of coastal areas and dune formation. He can often be found sitting close to the Sand Motor counting grains of sand. It’s all in aid of providing more accurate predictions of the long-term changes affecting the coastal landscape.
Delft model protects wind turbines from risks posed by sea ice
Researcher Hayo Hendrikse (CEG) has developed a new model that gives accurate calculations of the effects of sea ice on offshore structures, such as wind turbines and oil and gas platforms. It turns out that ice causes less wear and tear in these structures than was previously assumed. Thanks to a successful partnership with Siemens Gamesa, Hendrikse's model is now being used in the construction of new offshore wind farms.
Into the mud to help nature
Intertidal flats: you might know them from the Wadden Sea area, but they can also be found in the south-western region of the Netherlands. An intertidal flat is an area that is underwater at high tide and above water at low tide, explains De Vet. “The water can rise or fall by five metres within six hours. At low tide, this creates small islands and strips along the coast (tidal flats)”. Intertidal flats are of great ecological value. The lugworms, cockles and crabs living in these areas make them an important pit stop for migratory birds.
Can sandbanks save mangrove forests?
Waking up early and going into the field on a small fishermen's boat, while the sun is rising behind volcano tops. That's how days started for PhD student Silke Tas during her two month fieldwork in Indonesia. The rest of her days were less idyllic: they consisted mostly of treading through the mud to get the right measurements for her research. She studies the workings of coastal sandbanks that give a chance to mangrove forests to restore, so that the forests can, in turn, prevent coast erosion.
Waiting for the perfect storm
For months hydraulic engineer Patrick Oosterlo has been waiting for a heavy storm. One that can truly test his equipment that was installed in and on a dike on the coast of the eastern Wadden Sea. He needs high waves and strong winds to decide: is this dike high enough?
