Large-scale Experiments of Tsunamis Generated by Iceberg Calving (2019)
Conference Proceeding
Heller, V., Attili, T., Chen, F., Brühl, M., Gabl, R., & Fuchs, H. (2019). Large-scale Experiments of Tsunamis Generated by Iceberg Calving. https://doi.org/10.3850/38WC092019-0800

Iceberg calving at outlet glaciers contributes to global sea-level rise in the context of climate change. This study investigates tsunamis generated by iceberg calving, so-called iceberg-tsunamis. Such tsunamis reached amplitudes of 50 m in the recen... Read More about Large-scale Experiments of Tsunamis Generated by Iceberg Calving.

© 2019 Elsevier B.V. Large landslide-tsunamis are caused by mass movements such as landslides or rock falls impacting into a water body. Research of these phenomena is essentially based on the two idealised water body geometries (i) wave flume (2D, l...

Large-scale experiments into the tsunamigenic potential of different iceberg calving mechanisms (2019)
Journal Article

Mass balance analysis of ice sheets is a key component to understand the effects of global warming. A significant component of ice sheet and shelf mass balance is iceberg calving, which can generate large tsunamis endangering human beings and coastal...

A numerical landslide-tsunami hazard assessment technique applied on hypothetical scenarios at Es Vedrà, offshore Ibiza (2018)
Journal Article
Tan, H., Ruffini, G., Heller, V., & Chen, S. (2018). A numerical landslide-tsunami hazard assessment technique applied on hypothetical scenarios at Es Vedrà, offshore Ibiza. Journal of Marine Science and Engineering, 6(4), 111. doi:10.3390/jmse6040111

This study presents a numerical landslide-tsunami hazard assessment technique for applications in reservoirs, lakes, fjords, and the sea. This technique is illustrated with hypothetical scenarios at Es Vedrà, offshore Ibiza, although currently no evi...

A laboratory-numerical approach for modelling scale effects in dry granular slides (2018)
Journal Article

Granular slides are omnipresent in both natural and industrial contexts. Scale effects are changes in physical behaviour of a phenomenon at different geometric scales, such as between a laboratory experiment and a corresponding larger event observed...

Self-similarity and Reynolds number invariance in Froude modelling (2016)
Journal Article
Heller, V. (in press). Self-similarity and Reynolds number invariance in Froude modelling. Journal of Hydraulic Research, 55(1), doi:10.1080/00221686.2016.1250832

This review aims to improve the reliability of Froude modelling in fluid flows where both the Froude number and Reynolds number are a priori relevant. Two concepts may help to exclude significant Reynolds number scale effects under these conditions:... Read More about Self-similarity and Reynolds number invariance in Froude modelling.

Tsunami science and engineering (2016)
Book
(2016). V. Heller (Ed.), Tsunami science and engineering. MDPI AG

In 2013, I was approached by the editorial team of the Journal of Marine Science and Engineering to act as guest editor of a Special Issue on tsunamis. I was very keen to take on this project given that recent tragic events such as the 2004 Indian Oc... Read More about Tsunami science and engineering.

Composite modelling of subaerial landslide-tsunamis in different water body geometries and novel insight into slide and wave kinematics (2016)
Journal Article

This article addresses subaerial landslide-tsunamis with a composite (experimental-numerical) modelling approach. A shortcoming of generic empirical equations used for hazard assessment is that they are commonly based on the two idealised water body...

On the effect of the water body geometry on landslide–tsunamis: physical insight from laboratory tests and 2D to 3D wave parameter transformation (2015)

Preliminary landslide–tsunami hazard assessment is commonly based on empirical equations derived from wave channel (2D) or wave basin (3D) experiments. The far-field wave in 2D can easily be an order of magnitude larger than in 3D. The present study...

The significance of the impulse product parameter P is reviewed, which is believed to be the most universal parameter for subaerial landslide tsunami (impulse wave) prediction. This semi-empirical parameter is based on the streamwise slide momentum f... Read More about A universal parameter to predict subaerial landslide tsunamis?.
