Numerical validation of novel scaling laws for air entrainment in water (2021)
Journal Article
Catucci, D., Briganti, R., & Heller, V. (2021). Numerical validation of novel scaling laws for air entrainment in water. Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 477(2255), Article 20210339. https://doi.org/10.1098/rspa.2021.0339

The Froude scaling laws have been used to model a wide range of water flows at reduced size for almost a century. In such Froude scale models, significant scale effects for air-water flows (e.g. hydraulic jumps or wave breaking) are typically observe...

A numerical investigation of tsunamis impacting dams (2021)
Journal Article
Attili, T., Heller, V., & Triantafyllou, S. (2021). A numerical investigation of tsunamis impacting dams. Coastal Engineering, 169, Article 103942. https://doi.org/10.1016/j.coastaleng.2021.103942

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.

A glacier–ocean interaction model for tsunami genesis due to iceberg calving (2021)
Journal Article
Wolper, J., Gao, M., Lüthi, M. P., Heller, V., Vieli, A., Jiang, C., & Gaume, J. (2021). A glacier–ocean interaction model for tsunami genesis due to iceberg calving. Communications Earth & Environment, 2(1), Article 130. https://doi.org/10.1038/s43247-021-00179-7

Glaciers calving icebergs into the ocean significantly contribute to sea-level rise and can trigger tsunamis, posing severe hazards for coastal regions. Computational modeling of such multiphase processes is a great challenge involving complex solid–... Read More about A glacier–ocean interaction model for tsunami genesis due to iceberg calving.

Numerical characterisation and efficient prediction of landslide-tsunami propagation over a wide range of idealised bathymetries (2021)
Journal Article
Ruffini, G., Heller, V., & Briganti, R. (2021). Numerical characterisation and efficient prediction of landslide-tsunami propagation over a wide range of idealised bathymetries. Coastal Engineering, 167, Article 103854. https://doi.org/10.1016/j.coastaleng.2021.103854

Landslide-tsunamis are generated by masses, such as landslides or icebergs, impacting into water bodies. Such tsunamis resulted in major catastrophes in the recent past. Generic research into landslide-tsunamis has widely been conducted in idealised...
