About the Group

During the last forty years, solitary waves have been used as surrogate leading tsunami waves in laboratory studies. The data taken from the 2004 Indian Ocean tsunamis, however, show that the length and time scales for the solitary wave are too small in comparison with those of real tsunamis. This discovery poses a fundamental challenge for the tsunami research community, who currently interpret the existing results based on solitary wave theory. More importantly, this points to the need to investigate the feasibility of generating adequate long waves in a laboratory facility for laboratory research.

This research will use the newly installed wave makers with long strokes at the NEES tsunami facility at Oregon State University to test the hypothesis that the leading tsunami wave does not have sufficient time and distance to evolve into a solitary form, therefore challenging the currently used modeling approach for wave runup and other physical quantities based on the solitary wave.
