A total of 14 wave gauges are used. Among that, 12 wave gauges were used for wave elevation measurement, two near the wavemaker as input for active absorption. The positions of wave gauges are shown in Figure 2, and the coordinates and respective calibration constants are shown in Table 1. The sampling frequency of the wave gauge was 100 Hz.
