Landslide dam failure and flood hydraulics. Part I: experimental investigation
Cao, Zhixian; Yue, Zhiyuan; Pender, Gareth - In: Natural Hazards 59 (2011) 2, pp. 1003-1019
Landslide dam failure can trigger catastrophic flooding in the downstream. However, field observation of such flooding is rarely available, while laboratory experimental studies are sparse. The mechanism of landslide dam failure and the flood has so far remained insufficiently understood. Here,...

Landslide dam failure and flood hydraulics. Part II: coupled mathematical modelling
Cao, Zhixian; Yue, Zhiyuan; Pender, Gareth - In: Natural Hazards 59 (2011) 2, pp. 1021-1045
A coupled 2D mathematical modelling study of landslide dam failure and flood is presented, complementing our experimental investigation presented in the companion paper. The model is built upon the shallow water hydrodynamic equations. The governing equations are numerically solved using the...

Evaluation of the overflow failure scenario and hydrograph of an embankment dam with a concrete upstream slope protection
Chiganne, François; Marche, Claude; Mahdi, Tew-Fik - In: Natural Hazards 71 (2014) 1, pp. 21-39
The standard procedure in Quebec, Canada, for evaluating the failure of an embankment dam, per the Loi sur la sécurité des barrages, specifies a 30-min-long failure scenario with a breach width equal to four times the maximal height of the dam. We demonstrate a new method for evaluating the...
