Objectives

This manual (EurOtop) provides up-to-date guidance on assessing the overtopping performance of seawalls and dikes, drawn from European experience and expertise.

The manual outlines techniques for predicting the mean overtopping discharge and consequent flood volumes and drainage requirements for a range of seawall types.

Outcome

The manual draws on experiences from both Germany and the Netherlands. It incorporates the latest techniques and data from European and UK research on wave overtopping predictions.

EurOtop can help engineers analyse the overtopping performance of any type of sea defence or related shoreline structure in Europe. The methods described can be used for current performance assessments and for longer term design calculations.

An online calculation tool guides users through a series of steps to establish overtopping predictions for:

  • embankments
  • dikes
  • rubble mound structures
  • vertical structures.

This project ran from 2005 to 2008.
