Helleretal.(2009)identifiedthedimensionlesswavetypeproduct T¼S1/3M cos[(6/7)a] as the relevant number characterizing a landslide impacting a water body. Fig. 2 relates T versus the slide Froude number F for the 211 experiments of the present study (Fig. 2(a)) and for the present study including the data of Fritz (2002) with 137 runs and Zweifel (2004) with 86 runs (Fig. 2(b)). The symbols refer to Stokes-like waves (J), cnoidal-like waves (&), solitary-like waves (B), and bore-like waves (X). Data described with (*) were conducted in the range of possible scale effects with h¼0.150 m. These runs
