In the field of tsunami research, large boulders are used to calculate the transport energy and thus the energy of tsunamis from their displacement during an event. This method can provide crucial information for coastal specific risk assessments. In practical use, numerical and analytical models are often used which have shortcomings regarding the accuracy for exact assessments, since many parameters have been greatly simplified during the development of the models.

As a contribution for improving these models the IWW, together with Max Engel (Institute of Geography, University of Cologne) and Shiva P. Pudasaini (Institute of Geosciences, University of Bonn), has conducted experimental investigations with idealized and non-idealized (real world based) boulder models. The results show highly divergent boulder behavior (e.g. transport mode, distance) attributed (amongst others) to the influence of the boulder shape and have now been published in the journal "Earth Surface Processes and Landforms" as article.
