Perimeter of PPRI 2013 Dordogne and tributaries to Altillac — 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.

2013年多尔多涅河及其支流至阿尔蒂亚克段的洪水风险预防计划（PPRI）边界——科雷兹省

覆盖科雷兹省利乌尔德尔地区15个市镇的多尔多涅流域及其阿尔塔段支流自然洪水风险预防计划（PPRI）

自然洪水风险预防计划（PPR）依据《环境法典》第L.562-1条制定。在风险暴露区域，将根据风险强度划定建设与设施禁止区以避免加剧风险；对于可批准建设与设施的区域，则明确相应的建设实施要求。

本次多尔多涅流域及其阿尔塔至利乌尔德尔段支流的洪水风险预防计划（PPRI）于2013年10月30日获批，共覆盖15个市镇（每个市镇对应一份PPRI）。涉及河道包括多尔多涅河、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。

本次风险研判基于水文模型推演得出。参考洪水标准如下：苏维涅河、萨涅河与菲勒勒河采用有记录以来的最强历史洪水（1960年10月洪水事件）；多尔多涅河、马罗讷河、马尔法尔热河、梅努瓦尔河与塞鲁克斯河则采用计算得出的百年一遇洪水。

本规划旨在防范洪水对人员与财产造成的风险。据此，洪水风险管控区域被划分为三类：红色区域（禁止建设）、深蓝色区域（符合条件可开展经济活动类建设）以及蓝色区域（符合条件可进行建设）。

各对应市镇的PPRI分别为：多尔多涅河畔阿尔塔、奥特法热、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。
