Extreme Hydrodynamic impact onto buildings

Davide Wüthrich

Dam failures, impulse waves, tsunamis and storm surges are disasters that challenge humanity, often leading to massive casualties and important economic losses. These events generate highly unsteady flow conditions in the form of surges or turbulent bores, ...

Effect of bed roughness on tsunami-like waves and induced loads on buildings

Anton Schleiss, Michael Pfister, Davide Wüthrich

Tsunami, impulse-waves and dam-break waves afflict humanity with casualties and damages. An insight into the flow mechanisms of these waves is important to provide safety and reduce reconstruction costs. This experimental study focuses on the effect of bed ...

Effect of debris damming on wave-induced hydrodynamic loads against free-standing buildings with openings

Anton Schleiss, Michael Pfister, Davide Wüthrich, Claudia Ylla Arbos

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 ...

Experimental and Numerical Study on Scour-Protection Methods in a Stilling Basin: Case Study of Chancy-Pougny Dam

Anton Schleiss, Giovanni De Cesare, Erik Bollaert, Sabine Chamoun, Davide Wüthrich

Chancy-Pougny is a run-of-river dam on the Swiss–French border constructed in the early 1920s. Since its commissioning, the operation of the four spillway gates has been responsible for a progressive erosion of the stilling basin. The future scour potentia ...

Experimental study on the hydrodynamic impact of tsunami-like waves against impervious free-standing buildings

Anton Schleiss, Michael Pfister, Davide Wüthrich

Tsunamis, landslide-generated waves, and dam failures are rare, but highly destructive phenomena, associated with extreme loading on infrastructure. Recent events showed that specific measures must be taken to guarantee safety of both people and the built ...

Aeration Performances of a Gabion Stepped Weir with and without Capping

Davide Wüthrich

The stepped spillway design has been used for more than 3,300 years. A simple structure is the gabion stepped weir. A laboratory study was performed herein in a large size facility. Three gabion stepped weirs were tested with and without capping, as well a ...

Experimental study on forces exerted on buildings with openings due to extreme hydrodynamic events

Anton Schleiss, Michael Pfister, Davide Wüthrich

Previous studies and field surveys showed that specific structural designs can decrease the load on free-standing buildings along the coast, providing safer vertical shelters. This experimental study investigated the effect of openings in buildings (window ...

Surface Turbulence on Bores and Surges propagating on Smooth and Rough Beds

Anton Schleiss, Pedro Filipe De Almeida Manso, Michael Pfister, Davide Wüthrich

Hydrodynamic waves are characterised by unsteady, highly turbulent and irregular behaviours. In nature, such phenomena can be observed in dam breaks, impulse waves and tsunamis. Both wet bed bores and dry bed surges were experimentally reproduced on smooth ...

Numerical approach in the study of tsunami-like waves and comparison with experimental data

Giovanni De Cesare, Michael Pfister, Davide Wüthrich

A comprehensive understanding of physical phenomena based on a hybrid experimental-numerical approach supports a safer design of critical infrastructures. However, for large-scale tsunami-like waves, the reliability of numerical models was insufficiently v ...

Estimation of wave propagation velocity on a channel with smooth and rough bed

Anton Schleiss, Michael Pfister, Davide Wüthrich

Natural hazards such as tsunamis, impulse waves and dam-break waves are rare, but extremely destructive. In recent times, more importance was given to structures that could withstand such events, however, uncertainties still exist in the estimation of wave ...

Experimental and numerical study on wave-impact on buildings

Giovanni De Cesare, Michael Pfister, Davide Wüthrich

Unsteady flows such as tsunamis, impulse waves and dam-break waves can lead to damages and human losses. Hence, specific research to limit casualties and reconstruction costs is needed. The complexity of the phenomena involved suggests that a hybrid experi ...

Experimental generation of tsunami-like waves

Anton Schleiss, Michael Pfister, Davide Wüthrich

In the context of a comprehensive research project investigating the hydrodynamic loading on structures with openings, this paper focuses on the wave generation techniques currently used and the test results associated with it, proposing a particular tsuna ...

Hydraulics, Air Entrainment, and Energy Dissipation on a Gabion Stepped Weir

Davide Wüthrich

In the last decades the design of stepped spillways regained some interest because of their suitability with new construction methods including gabions. The hydraulic performances of gabion stepped weirs were investigated experimentally in terms of the flo ...

Forces on buildings with openings and orientation in a steady post-tsunami free-surface flow

Anton Schleiss, Michael Pfister, Davide Wüthrich

Steady free-surface flows around buildings occurring during flood or tsunami events can produce major damages and a quantification of the post-peak forces is essential for safety and resilience of coastal structures. The loading process is highly affected ...

Hybrid modelling approach to study scour potential of Chancy-Pougny dam stilling basin

Anton Schleiss, Giovanni De Cesare, Erik Bollaert, Sabine Chamoun, Davide Wüthrich

Chancy-Pougny is a run-of-river dam on the Swiss-French border constructed in the early 1920s. Since its inauguration, the operation of the four spillway gates was responsible for a progressive erosion of the stilling basin. Thus, a hybrid modelling was pe ...

Velocity profile measurements in bore waves

Anton Schleiss, Giovanni De Cesare, Michael Pfister, Davide Wüthrich

Hydrodynamic waves are an unsteady flow motion generated by rapid water level rise. In nature, such events can be found in dam-break waves, impulse waves and tsunamis. These phenomena are rare, but highly destructive. The present study is based on an exper ...

Behaviour of a scour protection overlay with randomly distributed concrete prisms in plunge pools downstream of mobile barrages for exceptional operation conditions

Anton Schleiss, Giovanni De Cesare, Pedro Filipe De Almeida Manso, Sabine Chamoun, Davide Wüthrich

Uncontrolled scour is affecting multiple mobile dams. The plunge pool of the Chancy-Pougny barrage, located on the Rhone River bordering France and Switzerland, has recently been reported to develop in a potentially unfavourable direction after almost 100 ...
