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年科尔雷兹省福热地区多尔多涅河及其支流的PPRI专项方案

科尔雷兹省利乌尔德尔地区阿尔让塔河段多尔多涅流域及其支流的自然洪水风险预防计划（PPRI），覆盖15个市镇。

自然洪水风险预防规划需依据《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禁止建设与安装的区域，以避免加剧洪水风险；在可获批建设与安装的区域，则需明确具体实施要求。

2013年10月30日获批的多尔多涅流域及其阿尔让塔至利乌尔德尔段支流的PPRI，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。参考洪水标准为：苏维涅河、萨涅河与菲德莱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、马勒法尔热河、梅努瓦尔河以及塞鲁河则采用百年一遇计算洪水。

本规划的制定目的为防范洪水对人员与财产造成的风险。为此，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（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）。

各对应市镇的PPRI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、阿斯蒂亚克以及利乌尔德尔。
