Impulse wave – wave generation (2)

Impulse wave - wave generation (2)

Description

This photo shows a subaerial landslide generated impulse wave in a hydraulic model at VAW. The wave profiles are measured with Capacitance Wave Gages CWG. The test parameters are: still water depth 0.300 m slide thickness 0.235 m slide impact velocity 6.66 m/s bulk slide volume 0.0334 m3 bulk slide density 1,634 kg/m3 grain density 2,745 kg/m3 slide mass 54.6 kg grain diameter 4 mm slide impact angle 90° slide width 0.500 m The granulate impacts the wave channel bottom. A water splash larger than the 1 m high wave channel develops associated with an air cavity much larger than the bulk slide volume, between the slide surface and the water body, resulting in an almost vertically lifted water body.
