Abstract. A rocky granular flow is commonly formed after the failure of rocky bank slopes. An impulse wave disaster may also be initiated if the rocky granular flow rushes into a river with a high velocity. Currently, the granular mass–water body coupling study is an important trend in the field of landslide-induced impulse waves. In this paper, a full coupling numerical model for landslide-induced impulse waves is developed based on a non-coherent granular flow equation, i.e., the Mih equation. In this model, the Mih equation for continuous non-coherent granular flow controls movements of sliding mass, the two-phase flow equation regulates the interaction between sliding mass and water, and the renormalization group (RNG) turbulence model governs the movement of the water body. The proposed model is validated and applied for the 2014 Tangjiaxi landslide of the Zhexi Reservoir located in Hunan Province, China, to analyze the characteristics of both landslide motion and its following impulse waves. On 16 July 2014, a rocky debris flow was formed after the failure of the Tangjiaxi landslide, damming the Tangjiaxi stream and causing an impulse wave disaster with three dead and nine missing bodies. Based on the full coupling numerical analysis, the granular flow impacts the water with a maximum velocity of about 22.5 m s−1. Moreover, the propagation velocity of the generated waves reaches up to 12 m s−1. The maximum calculated run-up of 21.8 m is close enough to the real value of 22.7 m. The predicted landslide final deposit and wave run-up heights are in a good agreement with the field survey data. These facts verify the ability of the proposed model for simulating the real impulse wave generated by rocky granular flow events.

This paper is the accepted version published in Quarterly Journal of Engineering Geology and Hydrogeology, 49(4), pp. 279-285. http://qjegh.lyellcollection.org/content/49/4/279 © Geological Society of London 2016. ; © 2016 The Author(s). On 9 April 2000, a 91 Mm 3 rock avalanche occurred in Linzhi Prefecture, Tibet. The event was accompanied by a deafening noise, with the rock mass travelling from a maximum elevation of 5132 m and coming to a rest at an elevation of 2163 m. It formed a landslide dam in the Yigong Zangbo River of some 55 mheight, impounding a reservoir of some 2 Gm 3 for a period of 62 days after which it emptied in less than 12 h. This event was a forewarning of a period of frequent geological disasters in China during the start of the 21st century. The ensuingWenchuan earthquake (surface-wave magnitude M s 8.0; May 2008), Zhouqu debris flow (August 2010) and Ludian earthquake (M s 6.7; August 2014) led to the Chinese Government renewing its campaign against geological disasters and it has since invested heavily in scientific research to guide efforts to mitigate the impact of such natural disasters. This thematic set on Landslide Research in China was initiated to highlight this research. This paper provides a brief review of three of the featured subjects and accompanies the five papers published in the thematic set.
