Scaling approaches and scale effects in wave–flexible structure interaction (2023)
Journal Article

Laboratory models are important for research, to inform design solutions and to calibrate and validate numerical models. Unfortunately, model-prototype similarity is often difficult to achieve in small models, resulting in scale effects. For Wave–Fle...

A numerical investigation of tsunamis impacting dams (2021)
Journal Article

Landslides, rockfalls, and iceberg calving impacting into a water body generate large landslide-tsunamis posing a serious hazard in lakes and reservoirs. These waves can impact and even overtop dams as in the 1963 Vajont disaster in Italy. However, e... Read More about A numerical investigation of tsunamis impacting dams.
