Large-scale experiments into the tsunamigenic potential of different iceberg calving mechanisms (2019)
Journal Article
Heller, V., Chen, F., Brühl, M., Gabl, R., Chen, X., Wolters, G., & Fuchs, H. (2019). Large-scale experiments into the tsunamigenic potential of different iceberg calving mechanisms. Scientific Reports, 9(1), doi:10.1038/s41598-018-36634-3

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... Read More

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... Read More

A laboratory-numerical approach for modelling scale effects in dry granular slides (2018)
Journal Article
Kesseler, M., Heller, V., & Turnbull, B. (in press). A laboratory-numerical approach for modelling scale effects in dry granular slides. Landslides, doi:10.1007/s10346-018-1023-z. ISSN 1612-510X

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... Read More

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. ISSN 0022-1686

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

On the effect of the water body geometry on landslide–tsunamis: physical insight from laboratory tests and 2D to 3D wave parameter transformation (2015)
Journal Article
Heller, V., & Spinneken, J. (2015). On the effect of the water body geometry on landslide–tsunamis: physical insight from laboratory tests and 2D to 3D wave parameter transformation. Coastal Engineering, 104, doi:10.1016/j.coastaleng.2015.06.006

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... Read More

A universal parameter to predict subaerial landslide tsunamis? (2014)
Journal Article
Heller, V., & Hager, W. H. (2014). A universal parameter to predict subaerial landslide tsunamis?. Journal of Marine Science and Engineering, 2(2), doi:10.3390/jmse2020400. ISSN 2077-1312

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
