Abstract:
This paper describes the 2D physical model tests performed for a rock armour breakwater at LNEC´s facilities, under the framework of the HYDRALAB+ project. The aim of the present work was to evaluate damage evolution under different approaches of storm sequences, corresponding to different climate change scenarios. The tested wave conditions intended to simulate different sequences of water levels (low water and high water), significant wave heights and peak periods. Damage evaluation was based on the traditional visual method and on stereo-photogrammetric techniques. Results in terms of the non-dimensional damage parameter, the non-dimensional damage depth and the percentage of displaced armour units are compared for the different storm sequences.
