“…The PISCES modules used in this study were the finite element flow module, TELEMAC-2D (Hervouet et al, 1994), the finite difference wave module, FDWAVE (Southgate and Goldberg, 1989), and the sand transport model, SANDFLOW. A local model was nested directly within a regional model.…”

“…Gomes-Pereira and Wicherson, 1999;Rabus et al, 2003;Westaway et al, 2003), and the continued development of efficient numerical tools for predicting flood inundation and extent (e.g. Hromadka and Yen, 1986;Syme, 1991;Bechteler et al, 1994;Hervouet et al, 1994;Bates and De Roo, 2000;Frank et al, 2001;Horritt, 2004). However, unprecedented scope for undertaking high-resolution hydrodynamic modelling of river-floodplain systems and producing assessments of flood risk at very fine spatial and temporal scales is not a panacea.…”

“…The study is carried out through the implementation of a cascade of two different numerical models. The first is a quasi-two-dimensional (quasi-2D) hydraulic model (Barkau 1997) for the simulation of the dike breach along the River Enza, whereas the second is based on a full 2D hydraulic model (Telemac-2D; Hervouet et al 1994) for the simulation of flood dynamics. The topographic analysis of the study area was performed in a GIS environment, integrating the airborne LiDAR digital terrain model (DTM, available for the whole area at a resolution of 1 m) with spatial information about the presence of civil infrastructures (e.g.…”

“…Flood dynamics in the lowland area are simulated using a 2D-finite element model (Telemac-2D, Hervouet et al 1994). This model solves, through an overall limited computational cost, the shallow water equations over an unstructured mesh describing the topographic discontinuities that interfere with the inundation process (e.g.…”

Scientific literature reports a plethora of numerical tools of different complexity (e.g. 1D, 2D rasterbased or full 2D models) for flood hazard and flood risk evaluation. The correct identification of the appropriate model still represents a key aspect in the overall flood hazard process even though the potential of these modelling instruments are increased by the availability of high computational resources and by the amount of high-resolution topographic data provided by recent survey techniques. Given this context the present analysis investigates the effects of minor drainage networks on the estimation of flood hazard in a flood-prone area along the Enza River, close to the village of Sorbolo a Levante (RE, northern Italy). By means of a full 2D hydraulic model (Telemac-2D), the effects of the drainage system is analysed using three unstructured meshes with different degrees of complexity: (1) the minor drainage system allows the possibility to convey water outside the study area (REF); (2) the drainage system is reproduced only in terms of preferential flow-paths (REF-noFlow); (3) the drainage network is completely neglected (REF-noDN). The analysis indicates that the maximum flood extent seems not to be influenced by the mesh schematization, while water depths and the total volume are significantly related to the model schematization. Even if this analysis refers to a specific case study and further investigations are needed, it shows the fundamental role of the drainage network in controlling water depth distribution and the duration of the inundation, which should be accurately reproduced by numerical models.
