“…To obtain the underlying empirical equations, the slide characteristics have been systematically varied in a number of subaerial landslide studies. This includes a substantial body of research conducted in wave channels (2D) (Noda, 1970;Wiegel et al, 1970;Kamphuis and Bowering, 1972;Slingerland and Voight, 1979;Huber and Hager, 1997;Monaghan et al, 2003;Walder et al, 2003;Fritz et al, 2004;Quecedo et al, 2004;Liu et al, 2005;Lynett and Liu, 2005;Zweifel et al, 2006;Ataie-Ashtiani and Nik-Khah, 2008;Heller et al, 2008;Abadie et al, 2010;Heller and Hager, 2010Fuchs et al, 2013;Heller andSpinneken, 2013, 2015) with fewer studies undertaken in wave basins (3D) (Huber and Hager, 1997;Panizzo et al, 2005;Mohammed and Fritz, 2012;Heller and Spinneken, 2015). All of the above studies are based on idealisations including a horizontal bottom, a fully-granular or fully-rigid slide, as well as wave generation and propagation in either 2D or 3D.…”

“…Heller and Spinneken (2013) conducted tests to study the influences of the slide Froude number, the relative slide thickness, and the relative slide mass on SALGW characteristics. Their experiments showed that block slides do not necessarily generate larger waves than granular slides, in disagreement with Ataie-Ashtiani and Nik-Khah (2008). However, they found both the wave amplitude and period in agreement with the findings of Ataie-Ashtiani and Nik-Khah (2008).…”

Subaerial landslide-generated waves (SALGWs) are among destructive hazards which have been not often studied in comparison with earthquake-generated tsunamis and submarine landslide-generated waves. This paper represents a brief review of the physical and numerical studies on SALGWs. Samples of the laboratory experiments are provided and it is highlighted that all the available data should be combined and studied collectively to overcome the discrepancies and improve our understandings of SALGWs. Commonly applied numerical approaches to simulate SALGWs are discussed. A Boussinesq-type model (LS3D) considering landslide as a rigid body, and a two-layer shallow-water type model (2LCMFlow) considering landslide as a layer of a Coulomb mixture are utilized to investigate the effects of landslide deformations on the characteristics of the landslide-generated waves (LGWs) based on a set of available experimental data. With a rigid landslide assumption, the maximum height of LGW is about 16% overstimated. Dense material deformes into a thick front-thin tail profile and induce a LGW consists of a larger wave crest than the wave trough while loose material shows a dam-break type behaviour with a LGW having a larger wave trough. A real case of SALGW is simulated by both models. The maximum LGW height predicted by the 2LCMFlow model which is closer to the physics is about 14% less than the equivalent value predicted by the LS3D model. On the other hand, the LS3D model, with the 4th order of accuracy of wave dispersion, simulates the LGW propagation stage more efficiently and with around 30% less runtime. Assessing the effects of the landslide initial submergence on the LGW characteristics shows that a semi-submerged, a submarine, and a subaerial landslides induce the largest wave crest, wave trough, and landslide runout distance, respectively. Combining different conceptual and mathematical models at the various stages of SALGWs initiation, propagation, transformations and runup can advance the current numerical practice, in this field, both from accuracy and computational efficiency point of views.

“…Once a moraine-dammed lake is breached, outbursts of flood from the moraine-dammed lake seriously threaten the human life, public and private properties downstream [Clague and Evans, 1993;Walder and Driedger, 1995]. Studies have been carried out to investigate the characteristics of impulsive surges, peak discharge of GLOFs, and formation process of debris flows downstream along a gully [Cenderelli and Wohl, 2001;Fritz et al, 2004;Ataie-Ashtiani and Nik-Khah, 2008;Cui et al, 2010]. However, little attention has been paid to the characteristics of surge waves induced by ice avalanches and their effects on the failure mechanism of a moraine dam.…”

In this article, experimental tests were conducted to study the characteristics of the surge wave and its effects on the failure process of a glacier dam. The results indicated that two obvious surges were monitored by pore pressure transducers (PPTs) when the blockage slid into water. The surge wave attenuated exponentially near the plunging location and then attenuated slowly when it propagated downstream. When the surge wave reached the glacier dam it climbed up along the dam and flew over. Sequential propagating surges exerting on the dam were one of the main factors causing the failure of the glacier dam. The failure mechanism of glacier dam triggered by the surge waves under different initial water supply conditions was primarily analyzed in this article.
