EuroTop revisited. Part 2: vertical structures

The European Manual for the Assessment of Wave Overtopping (“EurOtop”) was issued free on the internet in 2007 and is now used worldwide. The manual and the accompanying Neural Network give guidance on all aspects of wave overtopping. It was the result of synthesis of existing Dutch, UK and German guidance and new research findings arising out of projects such as the EC FP7 “CLASH” project. During and since writing, the manual team has identified gaps and areas in which other improvements and clarifications could be made. This paper presents a summary of new analysis of existing data on vertical and very steep walls. A companion paper revisits sloping structures (Van der Meer et al., 2013).
