Flood Hazard Mapping. Analysis of methodologies and examples
Cartographie de l'aléa inondation. Analyses de méthodes et d'exemples
Résumé
Irstea carried out in 2012 a bibliographical analysis on flood hazard assessment for the French Ministry in charge of the implementation of the Flood Directive. This work relied on a large but heterogeneous mine of information : published regional or national maps, technical notes, internet pages aimed at the general public, and research papers on various relevant fields (hydraulic models, calibration procedures, estimation of flood quantiles...). This document highlights selected conclusions of this work, and the resulting suggestions for flood hazard assessment and mapping. It is a summarized complement to the slides. The aim can not be to present all the methods in details, but to give an overview of the approaches, and to focus on some issues.
