Session A.3: Armour Stability

Jean-Paul Latham, Imperial College

The displacement maps obtained from laser scanning are a great tool for the forensic analysis of flume stability tests. What they cannot do is answer the key issue of forces and stresses in units that “rock” or settle, or the number of contacts that units make with neighbouring units or rock from the underlayer. Numerical models of single layer armour systems can capture all the displacement history and forces – however the ability to numerically model wave action and unit responses requires further development and validation. It would therefore be very helpful to try and combine efforts to model these structures physically and numerically.
