Title: Experimental and numerical investigation of landslide-tsunamis
Abstract: Subaerial landslide-tsunamis (impulse waves) are large water waves generated by mass movements such as landslides, rock falls, snow avalanches, glacier calving or meteoroids impacting into a water body. The most devastating examples include the 1958 Lituya Bay case where a run-up height of 524 m was observed, and the 1963 Vaiont case in Northern Italy, where a wave overtopped a dam by more than 70 m resulting in approximately 2,000 casualties. Dr Heller and his students conduct generic physical and numerical model tests to understand and predict these extreme waves. The seminar addresses results of a recently concluded NERC funded research project which looked into the effect of the water body geometry on landslide-tsunami characteristics. Currently ongoing research and funding efforts into tsunamis generated by ice calving and the loading of tsunamis, and ordinary water waves, on flexible structures are also highlighted.
