Les sirènes sont-elles pertinentes pour alerter la population en cas de crues rapides en France ?

Abstract : After different failures observed in the use of church tombs for alerting the population during the early 1930 and under a passive defense following the Second World War, the French government have decided to deploy the National Alert Network (NAN) since 1954. The signal sent by the sirens was intended to interrupt all the social activities, and the sound was likely to induce “adapted” behavior by the concerned authorities but also by the inhabitants. However, the NAN remains often not used to alert population, as recalled after the flash floods observed in the Aude basin river the 2018, October, 15th. Thus, this article involves to a further assessment and evaluation of supports and drawbacks of the NAN face to flash floods. Results obtained in the department of Vaucluse confirms that most of the sirens are not located in sensitive areas, thus we cannot hope to use such notifications for alerting the populations. Several improvements are explored, namely because the government has decided to replace this NAN with a new system, SAIP (System of Alert and Information for the Population), whose deployment began at the metropolitan scale in 2017 and whose operationality is expected for 2022.
