damage in a small-scale physical model. The methodology uses damage defined by 

 Equation 3.1 as the eroded area normalized by the square of the nominal stone diameter

In addition, three profile descriptors of engineering interest are suggested as 

 follows. The minimum cover depth (Equation 5.1), maximum eroded depth (Equation 

 5.2), and maximum eroded length (Equation 5.5) along the profile are normalized as

Data were obtained from an automated profiler on a traditional rubble mound 

 breakwater section. The profiler is shown to provide improved damage measurements, 

 as the cross-shore spatial sampling interval was less than 1 mm, which is considerably 

 smaller than traditional sounding measurements. In addition, the profiler was automated 

 making profiling very efficient. Because profiling did not require draining the wave
