Text en actes de congrés
Accés restringit per política de l'editorialThis paper presents the MARHIS network, an added value aggregation of hydraulic facilities and numerical modelling tools plus field equipment from the Catalonia University of Technology and IH Cantabria. The paper presents ... -
Tools for evaluation quay toe scouring induced by vessel propellers in harbour basins during the docking and undocking manoeuvring
Castells Sanabra, Marcel·la; Martínez de Osés, Francesc Xavier; Martín Mallofré, Agustí; Mujal Colilles, Anna; Gironella Cobos, Xavier (CRC Press, 2017)
Text en actes de congrés
Accés obertThe evolution of the shipping industry (increased capacity and size of ships, power and self-propulsion), the increased productivity and rearrangement of spaces (port calls increased in number and frequency, changes in use ... -
Tsunami hazards in the Catalan Coast, a low-intensity seismic activity area
Barranco, Ignasio; Gracia Garcia, Vicente; Sierra Pedrico, Juan Pablo; Perea, Hector; Gironella Cobos, Xavier (2017-09)
Article
Accés obertThe potential impacts of tsunamis along the Catalan Coast (NW Mediterranean) are analysed using numerical modelling. The region is characterized by moderate to low seismic activity and by moderate- to low-magnitude ... -
Twin propeller time-dependent scouring processes: physical experiments
Llull Marroig, Antoni Ignaci; Mujal Colilles, Anna; Gironella Cobos, Xavier (2021-09)
Article
Accés obertWe present a new set of experiments in local scour due to confined twin propeller jets aiming to include propeller driving characteristics to the analysis of the scouring action during in-port manoeuvres. The maximum scour ... -
Variability of wave impact measurements on vertical breakwaters
Marzeddu, Andrea; Oliveira, Tiago; Gironella Cobos, Xavier; Sánchez-Arcilla Conejo, Agustín (2017-11)
Article
Accés obertThe measurement of wave-induced impacts on structures involves significant scientific and engineering challenges. Regular nearly breaking pgbgand broken waves generated following cnoidal and first-order Stokes wavemaker ... -
Wave hydrodynamic forces over mooring lines on floating offshore wind turbines
Trubat Casal, Pau; Molins i Borrell, Climent; Gironella Cobos, Xavier (2020-01)
Article
Accés obertThe mooring loading of floating offshore wind turbines are mainly induced by the platform motions through the fairleads. The dynamic analysis usually only considers the hydrodynamic forces over the mooring by the motion ... -
Wave overtopping assessment in DualSPHysics for real sea states of 1000 random waves
Altomare, Corrado; Gironella Cobos, Xavier; Robustelli, Maria Luigia; Viccione, Giacomo (New Jersey Institute of Technology, 2021)
Text en actes de congrés
Accés restringit per política de l'editorialIn this work the numerical model DualSPHysics has been applied to study the complex phenomenon of wave overtopping characterising dike-promenade coastal defence layout. The model has been first validated, by comparing the ... -
Wave reflection on dissipative quay walls: an experimental study
Altomare, Corrado; Gironella Cobos, Xavier; Sánchez-Arcilla Conejo, Agustín; Sospedra Iglesias, Joaquim (2013)
Text en actes de congrés
Accés restringit per política de l'editorialThe paper discusses the influence of slope porosity and model scale for a low reflective vertical quay. Physical model tests were carried out in the small and large scale facilities at Universitat Politècnica de Catalunya, ... -
Wave reflection, transmission and spectral changes at permeable low-crested structures
Sierra Pedrico, Juan Pablo; Dowding, D.D.; Persetto, Vito; Oliveira, Tiago Castro Alves; Gironella Cobos, Xavier; Mösso Aranda, César; Mestres Ridge, Marc (2011)
Text en actes de congrés
Accés obertPhysical model tests were carried out in order to improve the understanding about the hydrodynamic processes that take place around a LCS when it is under wave attack. In particular, the wave transmission and reflection ... -
Wave reflection: small and large scale experiments on wave absorbing quay walls
