After upscaling the experimental results according to Froude similarity, the numerical tests have explored the effects of the choice of the options offered by the HEC-RAS 2D software with the default value of the parameters and the obtainable improvement when the geometry of the bridges suggested a customized value of parameters. The numerical results show a very good match with the measured water elevation upstream of the bridges for almost all tested cases. The mean absolute percentage error obtained pooling all the steady test cases is less than 5%. info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Pilotti, Marco Bonomelli, Riccardo Martínez-Aranda, Sergio Universidad de Zaragoza (orcid)0000-0003-4673-9073 García-Navarro, Pilar Universidad de Zaragoza (orcid)0000-0001-8674-1042 5001 600 Universidad de Zaragoza Dpto.
