Flooding of rivers — TRI Lille

The implementation of the Flood Directive aims to establish a framework for the assessment and management of flood risks at the level of the Artois — Picardy basin while prioritising state intervention for territories with significant flood risks (TRI). Risk of overflowing rivers of the Lys and its tributaries for a period of return 10 years (proba. strong), 100 years (average proba) or 1000 years (low proba): the event has a probability in 10, 100 or 1000 of happening each year on the Lille TRI. __Origin__ The noise levels emitted by a given infrastructure during an average day are evaluated using numerical models producing isophone curves translated into noise zones, according to the index recommended for all modes of transport at European level, namely the Lden index and the Ln index. The isophone curves, described by the resource N_BRUIT_ISOPHONE_L, are thus used to delimit the external and, where appropriate, internal boundaries of noise zones by index ranges. These noise zones are derived from vintage acoustic simulation models, updated on cases of imperative revisions duly identified in 2017 __Partner organisations__ DREAL HdF (Direction Régionale de l'Environnement de l'Aménagement et du logement des Hauts de France), DREAL HdF (Regional Directorate of l’'Environnement de l'Development and Housing of Hauts-de-France) __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-fcbd5c50-e2cd-4e6d-aee6-24fcd33c6d15) * [COVADIS data standard: Table describing Noise Areas of (to be completed)(http://geostandards.developpement-durable.gouv.fr/afficherPageStandard.do?jeu=N_BRUIT_ZBR_INFRA_S) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/2dc2a7298abe91a5c780a925fcddfaa035b29ccc)
