It is clear that increased attention to flood risk reduction, and to wave overtopping in particular, have increased interest and research in this area. This updated comprehensive manual gives up-dated guidance on many topics related to wave overtopping. Many projects describe EurOtop as the manual to be used for design. Many international researchers also now see improving the methods in EurOtop as targets for research. In revising the manual ourselves, we have seen that knowledge and new prediction methods, or knowledge on tolerable discharges, all continue to develop. These changes are however scattered and new methods may not necessarily have been well-reviewed or tested. But if new methods offer improvements, do we have to wait till a 3rd edition of EurOtop in 2030? Why not make EurOtop Live, and challenge researchers and practitioners around the world to help improve EurOtop?
So the challenge is for those wishing to improve EurOtop, they should give the background to their research (probably a paper or report), then they should indicate where and how the manual should be modified, indeed with a text proposal to translate research to application! In this way there should be less delay in re-writing the manual. Editing and checking new methods will require work, but perhaps no more than at present.
Therefore we have established a small EurOtop Live Board to review and edit new contributions. An optimistic view might be one meeting for each updated version every two years, supported by a few ‘virtual’ meetings to settle particular 'improvements'.
We challenge researchers and practitioners to come with improvements they see possible for the next EurOtop. They should provide:
- background to the improvement (paper or report), taking into account the data of the existing method (not just their own research neglecting existing data);
- the original data if needed for figures and/or checking;
- a text proposal for the next EurOtop, written for application of the improvement.
Submissions (or an abstract) will become available on the website on a "List of possible improvements". Approved submissions will appear in the next EurOtop. Possible submissions can be sent to: jmvandermeerconsulting.nl
