SICSS Excursion to the Large Wave Flume (Großer Wellenkanal, GWK)
On 14th March 2019, a little group of SICSS PhD candidates got on the train with the destination: Large Wave Flume (Großer Wellenkanal, GWK) in Hannover!
This flume is used for large-scale physical model tests on the effects of waves in terms of hydrodynamics, morphodynamics and ecological processes. At the time of our visit, Tsunami research was in progress, and Dr.-Ing. Stefan Schimmels explained us all about the art of creating waves, the destructive impact of tsunamis on structures, and the difficulty of scaling down experiments.
In the near future, the flume will be closed for construction- a more powerful wave maker will replace the old one and a current generator and a large pit will be added. This plan has already been realised in a downscaled version of GWK. Dr.-Ing. Markus Brühl presented the 1:10 wave flume for us, and waves were produced live for us to see.
Dr.-Ing. Nils Kerpen took over and presented the 3D wave basin to us, in which waves from all sides act on structures. The SICSS PhDs were encouraged to sign up for a slot in the tank in case we wanted to investigate any type of wave interaction for our projects.
With our heads full of waves, we ended the tour with a visit to a facility which tests different types of dike vegetations- which is where we took the group photo.
The Large Wave Flume is a joint institution of Leibniz University Hannover and Technische Universität Braunschweig.
