Abstract: The Brague river (South-east France) has been historically subjected to significant flooding events. This research primarily focuses on October 3,2015 flood event. Our analysis includes one of the main tributaries of the Brague river, namely the Valmasque. In the study domain, several hydraulic structures cross the river, which can hinder the river flow during extreme flood events. Our objective in this work is to assess the influence of culvert representation, within the domain on hydraulic discharge, and to examine the resultant variations in flood extents and water depth. In order to reach this goal, we propose to use the TELEMAC-2D modelling flood software to simulate a range of modelling approaches that accounts differently for the flow in the culverts area such as opened or closed topography or using culvert discharge equations.
