      Text en actes de congrés
      Accés restringit per política de l'editorial
      The open-source code DualSPHysics is used in this work to compute the wave run-up in an existing dike in the Chinese coast using realistic dimensions, bathymetry and wave conditions. The GPU computing power of DualSPHysics ...

    • Effect of wave storm representation on damage measurements of breakwaters 

      Marzeddu, Andrea; Oliveira, Tiago C.A.; Sánchez-Arcilla Conejo, Agustín; Gironella Cobos, Xavier (2020-03)
      Article
      Accés obert
      In this work, the effects of storm representation on damage measurements of a breakwater are studied in a small-scale physical wave flume. In particular, a two-layer breakwater with cubic armor units randomly placed is ...

      Present 3D printing technology allows the efficient design and construction of structures with complex shapes and high porosity satisfying biological and coastal protection demands. In this case, an array of ultra-porous ...

    • Experimental set-up and calibration errors for mapping wave-breaking pressures on marine structures 

      Marzeddu, Andrea; Stagonas, Dimitris; Gironella Cobos, Xavier; Sánchez-Arcilla Conejo, Agustín (2018-03)
      Article
      Accés obert
      Capturing the detailed spatial variation of pressures induced by breaking waves on physical model structures has become possible using a high resolution mapping system. It can provide data with 4 measuring points/cm2, ...

    • Impulsive wave loads on rigid structure, an experimental approach 

      Marzeddu, Andrea; Gironella Cobos, Xavier; Sánchez-Arcilla Conejo, Agustín (2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Within the European project ‘Hydralab IV’, HyRes we aim to improve the characterization of wave loads on rigid structures and the associated response by carrying out some laboratory experiments. Wave loads on rigid structures ...
