Abstract: The Brague river often encounters flash floods, resulting in consequent damages. The cities of Biot and Antibes were particularly affected in October 2015. This flood event was previously studied both using hydrological and hydraulic approaches, such as 2D hydraulic modelling tools (Basilisk, HEC-RAS and TELEMAC-2D) and the FEV approach. Here, we propose to restart from a previous existing numerical model built with TELEMAC-2D, which simulates the flood event of 2015 in the downstream area of the Brague river, based on a 2D approach on an unstructured mesh. The objective of this work is to check the HPC performance of TELEMAC-2D on this study case by considering different levels of mesh resolutions.
