PPRL Côte de Jade: Reference odds for Xynthia + 20 cm (reference event), in Loire-Atlantique

These data represent the height (NGF-IGN69) of the marine submersion that can be reached at any point in the territory exposed to risk under the Xynthia event + 20 cm (reference event) of the PPRL. This rating should be considered for the application of the regulatory provisions of the PPRL. These data are annexed to the Regulation of the PPRL. __Origin__ These data are derived from the modeling carried out by the IMDC study on the territory of the PPRL. Water inputs integrate failures of d'containment systems and hydraulic constructions. Modelling is performed for a marine level Xynthia+ 20 cm at the coast spreading in the land according to the digital field model Litto 3D (2010). __Partner organisations__ DDTM Loire-Atlantique __Links annexes__ * [XML metadata view](http://ogc.geo-ide.developpement-durable.gouv.fr/csw/all-dataset?REQUEST=GetRecordById&SERVICE=CSW&VERSION=2.0.2&RESULTTYPE=results&elementSetName=full&TYPENAMES=gmd:MD_Metadata&OUTPUTSCHEMA=http://www.isotc211.org/2005/gmd&ID=fr-120066022-jdd-45bfcd57-8726-4b1a-8355-ddb3104daad0) * [the Cote de Jade PPRL on the Service Portal of the Loire-Atlantique State](http://www.loire-atlantique.gouv.fr/Politiques-publiques/Risques-naturels-et-technologiques/Prevention-des-risques-naturels/Plans-Prevention-Risques-Naturels-Previsibles/Les-Plans-de-Prevention-des-Risques-Littoraux-en-Loire-Atlantique/Le-PPRL-Cote-de-Jade) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/61e9816a3a4aea1e4324e05c936c7c15727c4e01)
