IADC publishes study on the impact and costs of Building with Nature projects

The use of nature and natural processes is an innovative way to increase water safety and create added value through nature development and recreation.


IADC – International Association of Dredging Companies has released an exploratory study which was carried out to provide an initial inventory of the impact and costs of existing Building with Nature projects in the Netherlands.

The study also includes an analysis of the decision-making process in choosing this type of project and identifies success factors.

Building with Nature projects deliver added value but often also involve additional costs compared to traditional reinforcements.

These costs give an indication of what we as a society are prepared to pay for the development of nature and recreation as part of hydraulic engineering projects.

The study was prepared by Cees Oerlemans (HKV), Carolien Wegman (HKV), Bas Jonkman (Delft University of Technology) and Stefan Aarninkhof (Delft University of Technology).
