Details

This new manual offers up-to-date guidance to help users more accurately predict the rate of waves overtopping sea defences.

It is an update to the 2008 Wave Overtopping and Assessment (EurOtop) manual, a widely accepted, international best practice tool. It shares the best approaches for assessing overtopping in different scenarios, improving coastal flood forecasting and delivering more cost effective design of coastal flood defence schemes.

It is accompanied by an online calculation tool (Bayonet GPE) which helps users produce overtopping predictions for different types of sea defences, including embankments and dikes, rubble mound structures and vertical structures.
