Systèmes d’alerte précoce pour les aléas naturels et environnementaux : virage ou mirage technologique ?

Abstract: Les systèmes d’alerte précoce sont un moyen de réduction des risques naturels. Bien qu’ils soient appliqués depuis plusieurs décennies pour la plupart des aléas, notamment pour les aléas hydrométéorologiques et géologiques, ils sont généralement inefficaces. Le Québec est sujet à une multitude d’aléas hydrométéorologiques (verglas, déluge, submersion, érosion, etc.), certaines occurences dans les dernières décennies ont mené à un questionnement des acteurs quant à l’efficacité de réponse des systèmes en place.… Show more

“…Here we present with some detail the development of expression (3) utilized in Section 2. It is based on a model discussed by Sättele et al (2016), Didier et al (2017), Lopez et al (2020), and further developed in de Elia (2022), which we follow here. We have introduced some changes to make it more suitable for this work.…”

“…However, an important aspect that is left out in expression (A1) is the expenditure for the installation and maintenance of the protective and/or warning system. As the fourth term represents a cost unrelated with the activities of the system-inactivity is its "normal" statewe can take advantage of this term to represent installation and maintenance costs, as done by Didier et al (2017).…”

“…Another way to improve our understanding of the morphodynamics during this event would be to run XBeach with morphological updating, which introduces sediments In the present study, XBeach enhanced the understanding of storm impacts on the coast of Maria and contributed to a better understanding of the flood hazard not only in terms of static flood surface (spatial extent), but also in a more dynamic sense considering the timing, intensity, and duration of the event affecting the flow-related processes and the water depth. These are critical parameters in disaster risk management [83,84].…”
