Abstract:
This work evaluated a video camera-based technique for measuring wave run-up and identifying overtopping
events in three-dimensional physical scale models of rubble-mound breakwaters. Run-up elevations inferred
by the Timestack methodology were compared with the traditional measurements obtained by a resistive wave
gauge. For both frontal and oblique incident waves, run-up statistical parameters returned by Timestack
analysis agreed with the instrument measurements. Moreover, overtopping events were correctly identified.
Overall, results indicated the feasibility of a non-intrusive video camera-based technique for hydraulic
measurements in physical models.
