N_ZONE_REG_PPRN_20100011_L_019 Lines and values of isocotes of the reference flood of PPRI 2013 Dordogne and tributaries to Liourdes — 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_20100011_L_019 本数据集为科雷兹省利乌尔德尔片区2013年多尔多涅河及支流参考洪水的洪水位等值线（isocote）线值数据，对应多尔多涅河流域及其阿尔让塔至利乌尔德尔段支流的洪水风险防治规划（PPRI），该规划覆盖15个市镇。 自然洪水风险防治规划依据《环境法典》第L.562-1条制定。在洪水高风险区域，规划将根据风险强度划定禁止建设与布设设施的范围，以避免加剧洪水风险；对于可获批建设或布设设施的区域，则明确相关实施要求。 本次于2013年10月30日获批的多尔多涅河流域及其阿尔让塔至利乌尔德尔段支流的PPRI规划，覆盖15个市镇（每个市镇对应一份独立的PPRI规划）。涉及的河流包括多尔多涅河、马罗讷河、苏维涅河、萨涅河、菲勒勒河、马尔法尔热河、梅努瓦尔河与塞鲁河。本次洪水风险基于数值模拟推演得出：其中苏维涅河、萨涅河与菲勒勒河的参考洪水采用有记录以来的历史最大洪水（1960年10月洪水事件），多尔多涅河、马罗讷河、马尔法尔热河、梅努瓦尔河与塞鲁河的参考洪水则采用计算得到的百年一遇洪水。本规划的核心目标为防范洪水对人员与财产造成的风险，据此将防洪管控区域划分为三类：红色区域（禁止建设）、深蓝色区域（符合条件可开展经济类建设）、蓝色区域（符合条件可建设）。 各对应市镇的PPRI规划分别为：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、阿斯泰亚克与利乌尔德尔。
