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年多尔多涅河及其在科雷兹省布里夫扎克区域的洪水风险预防计划（PPRI）专项议题

科雷兹省利乌尔德尔片区阿尔让塔流域的多尔多涅河流域及其支流自然洪水风险预防计划，覆盖15个市镇。

自然洪水风险预防计划依据《环境法典》第L.562-1条制定。在风险暴露区域，计划将根据风险强度划定禁止建设与布设设施的区域，以避免加剧风险；对于可获批建设与布设设施的区域，则明确相应的实施要求。

本多尔多涅河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（每个市镇对应一份PPRI）。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、梅努瓦尔河以及塞鲁河。本次洪水风险基于数值模拟得出。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大历史洪水（1960年10月洪水事件），多尔多涅河、马罗讷河、马尔法尔热河、梅努瓦尔河以及塞鲁河则采用百年一遇计算洪水。本规制的核心目的为防范洪水对人员及财产造成的风险。据此，防洪管控区域被划分为三类：红色区域（不可建设）、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（符合条件可建设）。

每个市镇均对应一份PPRI，具体如下：多尔多涅河畔阿尔让塔、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、下巴桑亚克、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。
