PARAPETS

Large scale measurements of wave loads and mapping of impact pressure distribution at the underside of parapets

Hydralab IV, More than Water: 2010 – 2014

Facility: Large Wave Channel (GWK)

The Hydralab programme aims to provide access to eclusive hydraulic structures and facilities within the EU research area.

The Hydralab IV framework has a specific call for "Large scale measurements of wave loads and mapping of impact pressure distribution at the underside of parapets". The main goal of this project is to study the pressures that broken waves have on monolithic structures. The magnitude of the forces caused by this type of impact Ees much greater than that of non broken waves. In the past however n research ahs been carried out on this specific effec t of the phenomena. The information obtained will be used, together with the measurements of the incident wave hydrodinamic conditions and the generated overtopping, to increase the knowledge on this type of phenomena and to improve the existing numerical models. (Losada et al. (2008), Lara et al. (2008)). Design guidelines will also be presented.

The following are some of the secondary goals of the project: Como objetivos parciales del proyecto se pueden detallar:

  • Measure the forces induced by the broken waves and pressures on the monolithic structure.
  • Register the velocity and thickness of the overtopping jet and relate these variables with the incident wave conditions, the localization of the structure regarding the sea level , its longitude, shape and the registered overtopping.
  • Use the obtained results in the two previous goals to improve our knowledge on these types of events as well as on the numerical models used to simulate these phenomena.
