Damage to Rubble Mound Breakwaters – Extracting Design Guidance from ‘Old’ Test Data

The aim of this project has been to expand the concept of the CLASH overtopping database to include information on armour damage to rubble mound breakwaters and seawalls using a similar format. Response data have been entered under different armour types, and further distinction is made between different parts of the structure. To date, 2000 tests have been entered and proved the capacity of the database to summarize different rubble mound structures. This database can describe damage progression, thus improving analysis of lifetime risks for armoured rubble mound structures. Initial trials demonstrate the potential utility as a tool for validation and pre-design analysis.
