a relative leading wave length. b Ursell number just after generation for the different slide cases studied. For two particular slide volume (per unit width) (× points on plots (a) and (b)), free surface time series (hs = 0.75h0 (c) and hs = 2h0 (d)) at the gauges position (g) (with zero crossings depicted by red crosses). The corresponding wavelet scalograms (hs = 0.75h0 (e) and hs = 2h0 (f)) using Morlet motherwavelet62 are plotted with the energy of the signal component at each time/frequency point in m2. s−1 as colorbar. The leading wave period is depicted by the gray color extent on the free surface plots, and by the horizontal pink ribbon (i.e., leading wave frequency ± 10%) on the scalograms.
