Hazards areas of the Marine Submersion Risk Prevention Plan of St-Malo - Scenario 2100 – Ille-et-Vilaine (35)

: The Risk Prevention Plan of Submersion Marine de Saint-Malo was approved by order of the Prefect dated July 18, 2017. The MSRP is a regulatory document intended to improve the safety of people and property in the face of the risks of marine submergence. It aims as a priority not to aggravate the risks and to reduce vulnerability on the perimeters it covers, both from the point of view of future urbanization as well as the modalities of construction and uses of the territory. The boundaries of a hazard area are shown on the hazard map according to the hazard level. The intensity of the phenomenon of submersion is defined by the maps of hazards, taking a phenomenon of centenary occurrence. Scenario 2100 takes into account the current state of knowledge on the evolution at that time of the average level of the oceans. The simulations of submersion hazard are based on the parameters "horizontal velocity" and "water height" and are defined by the low, medium, strong and very strong hazard.
