Monitoring Individual Wave Characteristics in the Inner Surf with a 2-Dimensional Laser Scanner (LiDAR)

Figure 5

Example showing the wave extraction method in the inner surf zone. The wave-period-averaged water depth contours are shown in (a), where red dots represent the detected wave crests. The orange lines are the waves selected in this time window for the celerity calculations. Panels (b), (c), and (d) represent the water surface elevations at three cross-shore locations, with the chosen waves tracked across them. Extracted wave crests and troughs are represented by black circles and squares, respectively.
