Geometry-Based Preliminary Quantification of Landslide-Induced Impulse Wave Attenuation in Mountain Lakes

Abstract: In this work, a simple methodology for preliminarily assessing the magnitude of potential landslide-induced impulse waves’ attenuation in mountain lakes is presented. A set of metrics is used to define the geometries of theoretical mountain lakes of different sizes and shapes and to simulate impulse waves in them using the hydrodynamic software Flow-3D. The modeling results provide the ‘wave decay potential’, a ratio between the maximum wave amplitude and the flow depth at the shoreline. Wave decay potential i… Show more

“…In [70], different metrics of real alpine lakes were used to define the configuration of theoretical mountain basins of different sizes and shapes. These geometries were used in [70] to study LGW scenarios with a finite volume solver and to obtain correlations between the lake configuration and the landslide-generated waves. Here, we analyze one of the lakes considered in [70] to test the proposed coupled strategy in a 3D complex setup.…”

“…The Elliot Creek event is an example of a, sometimes underappreciated, hazard chain in high mountains experiencing rapid deglaciation. This event finds itself among other disastrous high mountain landslides that generate tsunami (Higman et al., 2018; Roberts et al., 2014) and floods and fast‐moving mass flows (Carey et al., 2012; Glancy & Bell, 2000; Franco et al., 2021; Hermanns et al., 2004; Hermanns, Dahle, et al., 2013; Hermanns, L’Heureux, et al., 2013; Hubbard et al., 2005; Oppikofer et al., 2012; Shugar, Jacquemart, et al., 2021; Vilca et al., 2021). Rapid glacier retreat may increase the hazard of these events as the number and size of lakes increase below potentially unstable slopes in alpine valleys undergoing ice retreat.…”
