Perimeter of PPRI 2013 Dordogne and tributaries to Nonards — 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年多尔多涅河及诺纳尔支流防洪风险规划（PPRI）范围——科雷兹省

本数据集对应科雷兹省利乌尔德尔地区多尔多涅流域及其阿尔让塔支流的自然洪水风险预防规划（PPRI）范围，涉及15个市镇。

自然洪水风险规划（PPR）的制定需符合《环境法典》第L.562-1条之规定。在洪水风险暴露区域，规划将根据风险强度划定建设与设施禁止区域，以避免加剧洪水风险；对于可获批建设与设施的区域，则明确相关实施要求。

本次多尔多涅流域及其阿尔让塔至利乌尔德尔支流的防洪风险规划（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。

本次洪水风险分析基于数值模拟模型生成。
参考洪水标准选取如下：苏维涅河、萨涅河与菲代勒河以有记录以来的最强历史洪水（1960年10月洪水）为基准；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计算得到的百年一遇洪水作为基准。

本规划的规制目的在于防范洪水对人员生命与财产造成的风险。
据此，规划将洪水安全区域划分为三类：红色区域（禁止建设）、深蓝色区域（符合条件可开展经济建设活动）以及蓝色区域（符合条件可开展建设活动）。

本次规划覆盖的15个市镇及其对应PPRI如下：多尔多涅河畔阿尔让塔、欧特法日、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、阿斯蒂亚克以及利乌尔德尔。
