## 1 Introduction
[PERSON] [11] investigated wave types generated by landslides in a two-dimensional physical laboratory model based on the generalized Froude similarity. [PERSON] [12] predicted the wave type directly by the diagram from the experiment, which was conducted by a prismatic wave channel. [PERSON] [13] investigated the influence of slide mobility on wave generation by an experiment in a 33.0 m long and 2.1 m wide horizontal wave flume. [PERSON] [14] studied the overall spatial distribution pattern of the maximum wave pressure by a generalized experimental model. [PERSON] [15] measured the high velocity and the geometry of a landslide as well as the generated wave characteristics by a non-intrusive system in a 4.10 m long and 2.44 m wide space. [PERSON] [16] used an experimental model coming from two aforementioned failure types in the Three Gorges Reservoir to study and compare slide kinematics and impulsive wave features. [PERSON] [17] derived empirical equations based on most experiments on the first maximum wave amplitude and the second maximum wave amplitude. [PERSON] [18] empirically derived the prediction equations based on experiments that were conducted at VAW in a 4.5 m by 8.0 m wave basin. [PERSON] [19] investigated the impulse waves generated by subaerial landslides of combined solid-block and granular materials based on two-dimensional (2D) laboratory tests. [PERSON] [20] developed empirical relationships linking the landslide parameters with the produced wave amplitude, propagation features, and energy by an experiment in a rectangular wave tank that had a length L of 4.10 m and a width W of 2.45 m.  
The prototype physical similarity test method consumes more manpower and material resources and takes a very long time, so this method was not frequently used by domestic and foreign research. Since the method adopts the Froude similarity criterion, it is closer to the actual engineering, and is of great significance for solving engineering problems and predicting landslide surge disasters. [PERSON] et al. [21] modeled planar lithic debris flowsalong the Urnersee River. [PERSON] [22] found that the three-dimensional wave basin experiments are applicable on a much wider prototype range than the two-dimensional wave channel. A potential landslide surge at Mica Reservoir was modeled by Western Canada Hydraulic Laboratories (WCHL) [23]. [PERSON] [24] constructed a large-scale physical Froude-similar model with a scale of 1:200 to produce impulse waves which were constructed based on the Chinese Gongjiafang landslide. [PERSON] [25] conducted a prototype scaled experiment considering the topography effect to propose empirical equations to predict the maximum wave amplitude and wave decay in the channel direction. Landslide-generated tsunami source and propagation scenarios were physically modelled in a three-dimensional tsunami wave basin by [PERSON] [26]. [PERSON] [27] designed the physical model abided by Froude similarity, without distortion, at a scale of 1:200. [PERSON] [28] put forward a multiple regression equation to evaluate the maximum wave amplitude in the generation region by conducting an experiment in a water wave channel model with 1:200 scale based on the topography of the Yangtze River, China. [PERSON] [29,30] considered the section of Wanzhou Jiangnan Tuokou Wharf within Three Gorges Reservoir as the test area to investigate the pressure on bank slopes under the effect of impulse waves generated by landslides. In general, empirical formulas, generalized models and numerical calculations have some discrepancies with engineering reality, while the prototype physical model test can better restore engineering reality, which has a higher credibility and practical value for the study of landslide surge. The river course characteristics and the landslide volume have an important influence on the head wave height of landslide surge and the climbing height of the dam surface.
