NCK theme day on Friday 17 November 2017: Three mega-nourishments along the Holland dune coast: a first comparison and appraisal

Context
The first evaluation of the Spanjaards Duin nature compensation project is approaching in 2020, the Sand Motor has had its first five-year evaluation in 2016, and the Hondsbossche Duinen project is now in place for almost three years. So far, however, sharing of experiences and insights between these three dune development projects has been limited.

Aim
This is a good opportunity to organize an NCK theme day on dune development. During this event, we aim to bring together the NCK and the dune community to compare insights of the three projects described above. Also, the event will facilitate exchange of knowledge between coastal researchers, dune management, industry and stakeholders on geomorphological and ecological processes in Dutch dune systems and the influence of sand nourishment thereon.
