Scale effects in subaerial landslide generated impulse waves

Evolution of water waves generated by subaerial solid landslide

Waves generated by aerial and subaerial landslides are studied experimentally, theoretically and numerically. A set of experiments are done in a wave tank of 18 m long, 0.65 m wide and 1.5 m deep. Numerical simulations are in good agreement with the experiments. Based on numerical and experimental results, we derive different scaling laws which show a good agreement with the experiments and the...

Shear Band and Landslide Dynamics in Submerged and Subaerial Slopes

A numerical study of submarine-landslide-generated waves and run-up

A mathematical model is derived to describe the generation and propagation of water waves by a submarine landslide. The model consists of a depth-integrated continuity equation and momentum equations, in which the ground movement is the forcing function. These equations include full nonlinear, but weak frequencydispersion, e¬ects. The model is capable of describing wave propagation from relativ...

Sonocatalysis – The effects of sound generated waves on catalytic chemistry

Power Ultrasound During the sonication of liquids, the accoustic wavelength range between approx. 110 and 0.15 mm for frequencies of 18kHz and 10Mhz. This is significantly higher than those of molecular dimensions, resulting in that there is between the molecules and the accoustic field no direct coupling of chemical species. The effects of sonication are mostly generated by the ultrasonic cavi...

Numerical simulation of waves generated by landslides using a multiple-fluid Navier–Stokes model

a r t i c l e i n f o This work reports on the application and experimental validation, for idealized geometries, of a multiple-fluid Navier–Stokes model of waves generated by rigid and deforming slides, with the purpose of improving predictive simulations of landslide tsunamis. In such simulations, the computational domain is divided into water, air, and slide regions, all treated as Newtonian...
