Public ISBD [article]  in Journal of hydraulic research > Vol. 49 Supplément 1 (2011) . - pp. 15-19 Titre : Composite modelling for large-scale experiments on wave–dune interaction Type de document : texte imprimé Auteurs : Giuseppe Roberto Tomasicchio, Auteur ; Felice D'Alessandro, Auteur ; Giuseppe Barbaro, Auteur Année de publication : 2012 Article en page(s) : pp. 15-19 Note générale : Hydraulique Langues : Anglais (eng) Mots-clés : Breaching  Composite  model  Dune  erosion  Large-scale  experiment  Overwash Index. décimale : 627 Ingénierie des cours d'eau naturels, des ports, des rades et des cotes. Installations de navigation, de dragage, de récupération et de sauvetage. Barrages et centrales électriques hydrauliques Résumé : The research describes the design aspects related to the large-scale physical model experiments conducted within the EU-Hydralab III Integrated Infrastructure Initiative, at the Canal d'Investigaciò i Esperimentaciò Mar‘ıtima, Laboratori d'Enginyeria Mar‘ıtima at Universitat Politècnica de Catalunya, Barcelona. The aim of the experimental investigation is to enlarge the knowledge on dune erosion, overwash and breaching processes during storm surges. An innovative ‘composite’ numerical model has been adopted to reach a model test setup valid to observe dune erosion, overwash and breaching. The use of the proposed approach provides a better insight into the physical problems thereby, reducing the uncertainties in selecting the optimum wave characteristics to be reproduced in the flume for a given beach–dune geometry.

Large-scale experiments on dune erosion processes / Giuseppe Roberto Tomasicchio in Journal of hydraulic research, Vol. 49 Supplément 1 (2011) 

Public ISBD [article]  in Journal of hydraulic research > Vol. 49 Supplément 1 (2011) . - pp. 20-30 Titre : Large-scale experiments on dune erosion processes Type de document : texte imprimé Auteurs : Giuseppe Roberto Tomasicchio, Auteur ; Agustin Sanchez-Arcilla, Auteur ; Felice D'Alessandro, Auteur Année de publication : 2012 Article en page(s) : pp. 20-30 Note générale : Hydraulique Langues : Anglais (eng) Mots-clés : Breaching  Dune  erosion  Large-scale  experiment  Numerical  model  Overwash Index. décimale : 627 Ingénierie des cours d'eau naturels, des ports, des rades et des cotes.

Barrages et centrales électriques hydrauliques Résumé : This research provides an overview of the large-scale physical model experiments conducted at the Canal d'Investigaciò i Esperimentaciò Mar‘ıtima, Laboratori d'Enginyeria Mar‘ıtima, Universitat Politècnica de Catalunya, Barcelona, within the EU-Hydralab III Integrated Infrastructure Initiative. The model tests have been carried out in a flume with a sandy dune exposed to a combination of water levels and wave conditions. Different regimes of wave attacks on the sandy beach/dune system were investigated. In particular, the study provides a unique set of large-scale physical data concerning the wave-induced dune overwash. Measurements of velocities, sediment concentrations and beach–dune profile evolutions were considered. The profile measurements have been used to calibrate and validate a numerical model predicting the beach–dune profile modifications over the near-shore region. The numerical model compares well with the experimental data.
