N_ZONE_REG_PPRN_20100005_L_019 Lines and values of the isocotes of the reference flood of the PPRI 2013 Dordogne and tributaries to Beaulieu sur Dordogne — Corrèze Plans for the prevention of natural flood risk PPRI of the Dordogne basin and its tributaries of Argentat in Liourdres (15 communes) in Corrèze Natural PPRs are established in accordance with Article L. 562-1 of the Environmental Code. In exposed areas, depending on the intensity of the risk, they shall define the prohibition zones for constructions and installations in order not to aggravate the risk, or, in areas where constructions and installations may be authorised, the implementation requirements. The PPRi of the Dordogne basin and its tributaries from Argentat to Liourdres, approved on 30/10/2013, cover 15 municipalities (one PPRi per municipality). The rivers concerned are Dordogne, Maronne, Souvigne and Sagne and Filèle, Malefarge, Ménoire and Cerou. The hazard is derived from a modeling. The reference flood is the strongest history known for Souvigne, Sagne and Fidèle (crue of October 1960) and the centennial flood calculated for Dordogne, Maronne, Malefarge, Ménoire and Céroux. The purpose of the regulations is to prevent the risk to people and property. For this purpose, the flood-free territory is classified as red (inconstructible), dark blue (constructable under conditions for economic activities) or blue (constructible under conditions) A PPRi is established for each municipality, i.e.: Argentat-sur-Dordogne, Hautefage, La-Chapelle-Saint-Géraud, Forgès, Saint-Chamant, Monceaux-sur-Dordogne, Bassignac-le-Bas, Reygades, Chenaillers-Mascheix, Brivezac (merged with Beaulieu-sur-Dordogne), Beaulieu-sur-Dordogne, Nonards, Altillac, Astaillac and Liourdres.N_ZONE_REG_PPRN_20100005_L_019 本数据集包含2013年多尔多涅（Dordogne）河及其支流（延伸至多尔多涅河畔博略）洪水风险预防计划（Plan de Prévention des Risques d'Inondation，PPRI）的标准洪水等水位线点位与对应数值——涉及区域为科雷兹省（Corrèze）。 科雷兹省利乌尔德尔（Liourdres）境内阿尔让塔片区多尔多涅流域及其支流的自然洪水风险预防计划（PPRI），共覆盖15个市镇。 自然风险PPRI的编制需符合《环境法典》第L.562-1条之规定。在洪水风险暴露区域，该计划将根据风险等级划定禁止建设与设施布设区域，以避免加剧洪水风险；对于可获批建设与设施布设的区域，则明确相应的实施要求。 本次多尔多涅流域及其支流（从阿尔让塔至利乌尔德尔）的PPRI于2013年10月30日获批，覆盖15个市镇（每市镇对应一份PPRI）。涉及河流包括多尔多涅河、马罗讷河、苏维涅河、萨涅河、菲莱尔河、马勒法尔热河、梅努瓦尔河以及塞鲁河。本次洪水风险基于模型推演得出：苏维涅河、萨涅河与菲德莱河的历史已知最大洪水为1960年10月洪水；多尔多涅河、马罗讷河、马勒法尔热河、梅努瓦尔河与塞鲁河则采用百年一遇计算洪水作为标准洪水。本规划的目的在于防范洪水对人员与财产造成的风险，据此将涉洪区域划分为三类：红色（不可建设）、深蓝色（符合条件可开展经济类建设）与蓝色（符合条件可建设）。 本次覆盖的15个市镇分别为：多尔多涅河畔阿尔让塔、奥特法日、拉沙佩勒-圣热罗、福尔热、圣沙芒、多尔多涅河畔蒙索、下巴西尼亚克、雷加德、谢奈耶-马谢、布里夫扎克（已与多尔多涅河畔博略合并）、多尔多涅河畔博略、诺纳尔、阿尔蒂亚克、阿斯泰亚克以及利乌尔德尔。
