To verify the feasibility of the new velocity correction equation, reflection analysis was performed using WAVELAB software for the case in this study. The wave elevation signal of one period is shown in 0, the incident is blue line and the reflected is black line. Overall amplitude reflection coefficient is 5%. It can be seen that the new velocity correction equation is effective for the case studied in this paper.
Time–Frequency Processing: Tutorial on Principles and Practice

Computational algorithms for many of these TFRs have been designed and disseminated on the World Wide Web (WWW). This was important in demonstrating that these signal representations can be very successful tools for processing both signals and systems in real-life applications. Some TFR software can be presently found at the following WWW sites: TFT toolbox, http://crttsn.univ-nantes.fr/˜auger/tftb.html by F. Auger, P. Flandrin, P. Gonçalvès and O.

Erosion protection by winter state of salt marsh vegetation
Published in Journal of Ecohydraulics, 2022
The wave surface elevation data measured by the ultrasonic wave gauges were analysed with the software WaveLab (version 3.742) (Frigaard and Andersen 2014). The number of waves in a sequence was calculated in the time domain analysis and the application of the zero-down-crossing method. Further analysis was then done in the frequency domain. Bandpass filters were applied with respect to the peak frequency of the wave spectrum to filter out noise from the wave signal (). The wave characteristics of this study are described by the spectral significant wave height the peak wave period mean energy wave period the wave length the wave steepness and the Iribarren number (Table 1). Details of the definition and calculation of these parameters are given by Kerpen et al. (2019). The height of the breaking wave the water depth at the break point the x-coordinates of wave breaking and the impact of this plunging wave on the water surface is calculated according to literature (Larson et al. 1989, Figure 2, Table 1).
