Physical modeling of tsunamis generated by subaerial, partially submerged, and submarine landslides

Three‐Dimensional Physical Modeling of Tsunamis Generated by Partially Submerged Landslides

“…3D experiments were also conducted by Grilli and Watts (2005), Watts et al (2005) and Fujii et al (2018). While Grilli and Watts (2005) and Watts et al (2005) used a solid-block, Grilli et al (2017) and Takabatake et al (2020) used deformable materials to model the landslide. In Ataie-Ashtiani and Najafi-Jilani (2008) and Fujii et al (2018), both of them were utilized as landslide materials.…”

“…Although experimental results would be useful for clarifying the characteristics of partially submerged landslide-tsunamis and developing a reliable predictive equation, existing studies (Cabrera et al, 2020;Fujii et al, 2018;Gómez et al, 2016;Huang et al, 2020;Takabatake et al, 2020), which investigated partially submerged landslide-tsunamis using laboratory experiments, do not provide a sufficiently large data set. More specifically, Gómez et al (2016) physically modeled the specific reservoir they were studying, and thus developing universal predictive equations is difficult based on their experimental results.…”

“…The number of cases considered in the 3D experiments of Fujii et al (2018) was also limited (only two partially submerged landslide cases were considered). Although Takabatake et al (2020) used a wider range of experimental conditions, the experiments were performed only in a wave flume, meaning that the 3D effects of partially submerged landslide-tsunamis could not be investigated. The experiments of Cabrera et al (2020) and Huang et al (2020) were also conducted in a 2D condition.…”

Numerical Simulations of Tsunami Wave Generation by Submarine Landslides: Validation and Sensitivity Analysis to Landslide Parameters

“…In particular, there are a few equations relating maximum initial landslide wave amplitude with S and d (Ataie-Ashtiani and Najafi-Jilani 2008; Takabatake et al 2020). The innovation of this research is a comprehensive sensitivity analysis of landslide parameters as well as the validation of the model using physical experiments that would make the model suitable for future applications.…”

Analysis and Modelling of Ship Manoeuvring Simulation in Landslide-Generated Waves

“…Bullard et al [7] used four different slide volumes to achieve a wide range of dimensionless landslide parameter values. Takabatake et al [8] investigated three types of landslide-generated tsunamis through laboratory experiments and revealed that the characteristics of the leading-wave decay and the trailing waves were enhanced. Scholars have established a ship manoeuvring motion method and have analysed ship manoeuvring motion characteristics.…”
