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.

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

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...

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), https://doi.org/10.3390/jmse2020400

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?.
