| description | <p>The absence of validation or comparison data for verifying flood mapping methods poses a significant challenge in developing operational hydraulic approaches. This article aims to address this gap by presenting a benchmark dataset for flash flood mapping in the French Mediterranean region. The dataset described in this paper (<a href="https://doi.org/10.57745/IXXNAY">https://doi.org/10.57745/IXXNAY</a>, <span class="cit" id="xref_altparen.1"><a href="#bib1.bibx41">Nicolle et al.</a>, <a href="#bib1.bibx41">2024</a></span>) includes flood hazard maps and simulation results of three actual flash flood events, all computed in a steady regime at a 5 <span class="inline-formula">m</span> resolution using a 2D SWE (shallow water equation) model (neglecting inertia) named Floodos <span class="cit" id="xref_paren.2">(<a href="#bib1.bibx14">Davy et al.</a>, <a href="#bib1.bibx14">2017</a>)</span>. Additionally, it includes the input data necessary (digital terrain models, inflow discharges, hydrographic network) for conducting similar simulations with other hydrodynamic modelling approaches in both steady and unsteady regimes. A comprehensive validation dataset, comprising observed flood extents, high water marks, and rating curves, is also provided, enabling a detailed evaluation of 2D hydraulic simulation results. The simulation results from Floodos, compared against stage–discharge rating curves available at gauging stations, yielded highly encouraging outcomes. The median error (sim.–obs.) was <span class="inline-formula">−</span>0.04 <span class="inline-formula">m</span> for the 2-<span class="inline-formula">year</span> return period and <span class="inline-formula">−</span>0.14 <span class="inline-formula">m</span> across all simulated return periods, ranging from 2 to 1000 <span class="inline-formula">years</span>.</p> |
