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.

2013年多尔多涅河及其支流在布里瓦扎克的PPRI区域议题——科雷兹省

科雷兹省利乌尔德尔地区阿尔让塔流域的多尔多涅河及其支流的自然洪水风险预防规划（PPRI, Preventive Plan for Natural Flood Risk），覆盖15个市镇。

自然洪水风险预防规划的制定需符合《环境法典》第L.562-1条之规定。在风险暴露区域，规划将根据风险强度划定禁止建设与设施布设区域，以避免加剧洪水风险；对于可获批建设及布设设施的区域，则明确相关实施要求。

本次针对多尔多涅河及其支流（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，每个市镇对应一份PPRI。涉及的河道包括多尔多涅河、马罗讷河、苏维涅河、萨涅河、菲莱尔河、马尔费尔热河、梅努瓦尔河以及塞鲁河。本次洪水风险评估基于数值模拟得出。参考洪水标准为：苏维涅河、萨涅河与菲莱尔河采用有记录以来的最大历史洪水（1960年10月洪水事件），多尔多涅河、马罗讷河、马尔费尔热河、梅努瓦尔河以及塞鲁河则采用百年一遇计算洪水。本规划的规制目的在于保护人员与财产免受洪水风险威胁。据此，无洪水风险区域被划分为三类：红色区域（不可建设）、深蓝色区域（可在满足特定条件下开展经济活动类建设）以及蓝色区域（可在满足特定条件下进行建设）。

各对应市镇均制定了单独的PPRI，具体包括：多尔多涅河畔阿尔让塔、奥特法日、拉沙佩勒-圣若罗、福尔热、圣尚芒、多尔多涅河畔蒙索、下巴锡尼亚克、雷加德、谢奈耶-马谢、布里瓦扎克（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、阿斯塔亚克以及利乌尔德尔。
