PPRL Baie de Bourgneuf Nord: Reference ratings for the Xynthia event + 20 cm (reference event), in Loire-Atlantique

These data correspond to the height (NGF-IGN 69) of marine submersion that can be reached at any point in the risk-exposed territory underneath; PPRL reference event (Xynthia+ 20 cm). This rating should be considered for the enforcement of the regulations of the Coastal Risk Prevention Plan (LPP). These data are an annex to the PPRL Regulation. __Origine__ These data are derived from the modelling performed by the IMDC study office defining the propagation of the submersion wave by the maximum water height at any point in the territory exposed to an event of the type Xynthia + 20 cm. The modelling incorporates hypotheses of protection system failures and the MNT Litto 3D 2010. __ Partner Organisations__ DDTM Loire-Atlantique __Links annexes__ * [XML view of metadata](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-0537297f-d42c-4393-b964-f23a911078fb) * [Internet portal of state services in Loire-Atlantique](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-Baie-de-Bourgneuf-Nord) [See this sheet on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/f9be33f1f8b76407efb89ccce5eb9865ba8c0e3f)
