Abstract

Wave impact has been identified as the main source of failure for coastal breakwater. While wave transformation over low to mild sloping beaches have been widely studied, shoaling, breaking, reflection and dissipation over steep and very rough slopes are much less documented, especially in situ. The Artha breakwater, south-west of France, is a composite breakwater sitting on top of a complex, steep bathymetry. The results of in-situ measurement of wave transformation in the block armor of this structure are presented here.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/T8IINpfcPUM

Highlights

  • South west of France is exposed to an energetic wave climate (Dodet 2010)

  • Coastal structure in that area are submitted to extreme wave conditions that can be destructive

  • In order to better understand wave impact on breakwater and in the lineage of experiments by De Rouville (1938) and Bullock (2007), a set of pressure sensors have been embedded in the submerged armor and in the wall of the Artha breakwater in St-Jean Luz, bay of Biscay
