Laurent Goutiere, Auteur ; Soares-Frazão, Sandra, Auteur ; Yves Zech, Auteur |This research presents experiments of dam-break flow on mobile bed in an abruptly expanding channel, the wider section being twice as wide as the narrow. The bed material consisted of coarse uniform sand. The flow near the one-sided flume expans[...]

Soares-Frazão, Sandra, Auteur ; Yves Zech, Auteur |This study relates to sudden transient flow of the dam-break wave type in an idealised city in order to investigate the effects of flow depth and velocity on such a city. Particularly, the study aims at assessing the ability of a finite-volume n[...]

Soares-Frazão, Sandra, Auteur ; Ricardo Canelas, Auteur ; Zhixian Cao, Auteur |In this paper, the results of a benchmark test launched within the framework of the NSF–PIRE project “Modelling of Flood Hazards and Geomorphic Impacts of Levee Breach and Dam Failure” are presented. Experiments of two-dimensional dam-break flow[...]

Atabak Feizi Khankandi, Auteur ; Ahmad Tahershamsi, Auteur ; Soares-Frazão, Sandra, Auteur |Experimental data related to the analysis of reservoir geometry effects on dam-break flows are provided. Four different reservoir plan shapes were considered, namely a long reservoir, a wide, a trapezoidal shaped and one with a 90° bend. Time va[...]

Testa, Guido, Auteur ; Zuccala, David, Auteur ; Alcrudo, Francisco, Auteur ; Mulet, Jontan, Auteur ; Soares-Frazão, Sandra, Auteur |This paper describes the experiments carried out on the flooding of an urban district model for the purposes of mathematical model testing and validation. A model urban district made up of concrete blocks has been placed in an instrumented physi[...]

Lhomme, Julien, Auteur ; Soares-Frazão, Sandra, Auteur ; Guinot, Vincent, Auteur |A two-dimensional shallow-water model is presented for the simulation of urban floods. The concept of porosity is used to account for the influence of the buildings on the flow patterns in the street network without a need for a refined grid. A [...]

Sylvie Van Emelen, Auteur ; Soares-Frazão, Sandra, Auteur ; Cyrus K. Riahi-Nezhad, Auteur |The City of New Orleans is surrounded by an intricate network of floodwalls and dikes built to protect it from flooding from the Mississippi River and Lake Pontchartrain. In 2005, following Hurricane Katrina, New Orleans experienced one of the m[...]

Soares-Frazão, Sandra, Auteur ; Lhomme, Julien, Auteur ; Guinot, Vincent, Auteur |Floodplains with urban areas have significant effects on inundation flows. Large-scale modelling of such zones thus requires a special treatment to involve those effects. This paper presents a shallow-water model with porosity to account for the[...]
