Impulse wave - wave propagation (6)


  • Impulse wave - wave propagation (6)

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 Due to the large wave height, the impulse wave behaves as a spilling breaker wave type with a white cap at about 5.5 m from the slide impact location.

This web site was launched by Prof. Michele Mossa of the Polytechnic University of Bari (Italy) with the initial support of Fondazione Caripuglia, Bari, Italy for the Research Project LIC-MON of 2003 and of the Project IMCA (Integrated Monitoring of Coastal Areas) financed by MIUR PON D.M. 593/00. Later, the initiative was supported with other Prof. Michele Mossa’s funds, most recently provided by the RITMARE Project.
