Vague de surf en bassin

A design of a wave pool for surfing is defined in this work. The geometry is designed in order to optimize the relatively small area available for the project. The bathymetry is suited to the different levels of surfers. A wave generation system composed o ...

The effects of slide cohesion on impulse-wave formation

Christophe Ancey, Zhenzhu Meng

Experimental studies of impulse-wave formation have mostly used rigid blocks or granular materials to mimic landslides at the laboratory scale. These studies have deduced that material deformability plays a key part in wave formation: the more rigid the sl ...

The effects of slide cohesion on impulse waves generated by landslides

Christophe Ancey, Zhenzhu Meng

When gravity-driven mass flows, such as avalanches and landslides, enter bodies of water, they can generate large impulse waves whose effects can be devastating. Experimental studies of impulse wave formation have mostly used rigid blocks or granular mater ...

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 ...

Single-spectrum prediction of kurtosis of water waves in a nonconservative model

Yves-Marie François Ducimetière, Debbie Eeltink

We study statistical properties after a sudden episode of wind for water waves propagating in one direction. A wave with random initial conditions is propagated using a forced-damped higher-order nonlinear Schrödinger equation. During the wind episode, the ...

Experimental comparison of tsunami generated by viscoplastic and granular slides.

Zhenzhu Meng

Tsunami induced by subaerial landslides threatens coastal areas. The waves have mostly been studied in the laboratory using sliding blocks or granular media hitting a water body, but none of these materials makes it possible to understand how sliding mass’ ...

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, ...

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

Anton Schleiss, Michael Pfister, Davide Wüthrich, Ioan Nistor

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 ...

Wave atlas for Swiss lakes: modeling design waves in mountainous lakes.

Azin Amini, Philippe Heller, Blaise Etienne Marceau Dhont

The present study aims to provide a comprehensive wave atlas for Swiss lakes. The atlas is an adequate tool that contains wave characteristics of extreme events derived from numerical calculations. Swiss lakes are surrounded by mountains, and the wind fiel ...
