1. Coping with long-term climate change involves many uncertainties. Several climate scenarios have been updated to support policies.
2. Over the past thirty years, it appears that a net natural supply of sediment from the sea to the Belgian west and east coasts has taken place, which has contributed to the soft coastal defence.
3. The technology to follow evolutions in beach morphology is available.
4. Providing sufficient sand on the beaches not only strengthens the beach itself, but also contributes to strengthening the dunes.
5. After a storm, our beaches recover at least partially, and this within a period of barely a few months.
6. Taking fundamental processes better into account is a good basis for understanding and simulating the patterns of coastal sediment transport.
7. The FLIAT model developed under CREST provides a solid basis for hinterland flood risk calculations.
8. Wider beaches reduce the impact of waves on the dikes.
9. Physical tests in the test facilities of Ghent University, Flanders Hydraulics and Deltares have largely contributed to estimating the impact of waves on hard structures.

The output of the CREST project is divided into four themes. For an extensive list of research results, please click here (only available in English).
