Predicting the occurrence and spatial extent of extreme avalanches is a longstanding issue. Using field data pooled from various sites within the same mountain range, authors showed that the avalanche size distribution can be described using either an extr ...
Landslides as secondary seismic effects are causing some patterns of soil failure that are often considered among the most destructive ones. In fact, the impact from triggered landslides has sometimes exceeded damage directly related to strong shaking and ...

With increasing of hydrological data records and the development of technologies for flood discharge estimation, as well as higher requirements on dam safety issues, a large number of existing dams require spillway rehabilitation to improve their hydraulic ...
Tsunamis, impulse waves, and dam-break waves are rare but catastrophic events, associated with casualties and damage to infrastructures. An adequate description of these waves is vital to assure human safety and to generate resilient structures. Furthermor ...
Porous cohesive materials can fail and collapse under compressive stresses. This mechanical behavior is generally referred to as anticrack and in snow, it is at the origin of catastrophic avalanches. In this study, we investigate how the microstructure of ...
Two headrace tunnels and the drainage tunnel were excavated by tunnel boring machines (TBMs) in Jinping II Hydropower Station. During TBM excavation, two types of slabbing failure were encountered in these deep buried marble tunnels. One is rock bursting a ...
Free crest spillways are hydraulically efficient and safe in operation. Since their discharge capacity is directly proportional to the crest length several types have been developed with the purpose to increase the length of the latter. Among these types t ...

When applied to mountain torrents, sediment transport formulae habitually overestimate the bedload by several orders of magnitude, even if they have been developed for steep slopes. The reason is that the influence of macro-roughness elements, such as larg ...

In flood protection engineering, side weirs or overflow dams are used to divert water in a controlled way into flood plains as soon as the discharge capacity of the main-channel is reached. Because of the lateral loss of water, the sediment transport capac ...

The physical modeling tests for the rehabilitation of St-Marc Dam with a PKW are presented. A particular focus is put on the energy dissipation downstream from the PKW. The adopted solution is a leaned “ski-jump gutter” placed at the contact line between t ...
