Phase 1: Fjord H120 - water depth h=1.2 m: Measurements of radial wave propagation, wave runup, landslide kinematics and deposit

The landslide tsunami generator (LTG) was deployed in the fjord scenario with a water depth of 1.2 m. The fjord configuration consists of the LTG mounted to a ramp with an opposing headland ramp 5.52 m from the toe of the landslide ramp. Both the landslide ramp and the opposing headland ramp were built at a slope of 1:2 (vertical:horizontal) or α = 27.1˚. Wave gauges were strategically placed in the basin along rays at various angles from the landslide source to describe the tsunami wave angular dependence. A hybrid system of runup wave gauges and camera recordings focused on the runup slope measured the wave runup. The deformable landside material consisted of naturally rounded river gravel. The landslide surface kinematics were recorded with a planar particle image velocimetry (PIV) setup. The landslide deposit was scanned with a multi-transducer acoustic (MTA) array.
