Abstract:
The assessment of damage evolution in scale model tests of rubble-mound breakwaters can
be achieved by comparing eroded depths and volumes between consecutive surveys. Aiming
to evaluate damage evolution on rubble-mound breakwater, scale model tests were recently
conducted on the maritime hydraulic facilities of the National Laboratory for Civil
Engineering. This paper focuses on the use of novel, non-intrusive survey methodologies
such as the Time of Flight (ToF) principle technique. In this study, damage evaluation is
based on the comparison of point clouds obtained before and after each test series, enabling
the calculation of eroded depths and eroded volumes and the estimation of displaced units by
using a non-dimensional damage parameter based on the eroded volume.
