Disclaimer
These methods and tools are provided free of charge and can assist in establishing preliminary
predictions for overtopping discharges for the structure types discussed in the EurOtop manual. They are not intended
to be used for detailed design or assessment of structures subject to wave overtopping. It is recommended that detailed
design or assessment of any structure use hydraulic model testing to verify the overtopping discharges where this is practicable.
Use of the tools and methods available on this website assumes that the user has read and understood the EurOtop - Wave
Overtopping of Sea Defences and Related Structures: Assessment Manual.

any use of the methods and tools provided. The Partners accept no liability for any loss or damage suffered by the user of the
