Perimeter of PPRI 2013 Dordogne and tributaries in Reygade — 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年科雷兹省雷亚德地区多尔多涅河及其支流洪水风险防治计划（PPRI）范围边界

科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自然洪水风险防治计划（PPRI），覆盖15个市镇。

自然洪水风险防治规划（PPR）依据《环境法典》第L.562-1条制定。在风险暴露区域，规划将根据风险强度划定建设与设施禁止区，以避免加剧风险；在可批准建设与设施的区域，则明确建设实施要求。

2013年10月30日获批的阿尔让塔至利乌尔德尔河段多尔多涅流域及其支流洪水风险防治规划（PPRi），覆盖15个市镇，每个市镇对应一份PPRi。涉及河流包括多尔多涅河、马罗讷河、苏维涅河、萨涅河、菲莱尔河、马勒法尔热河、梅努瓦尔河与塞鲁河。

本次洪水风险评估结果基于水文模型模拟得出。参考洪水标准为：苏维涅河、萨涅河与菲代勒河采用有记录以来的历史最大洪水（1960年10月洪水事件），多尔多涅河、马罗讷河、马勒法尔热河、梅努瓦尔河与塞鲁克斯河采用经计算的百年一遇洪水作为参考标准。

本规划的管控目标为防范威胁人员与财产安全的洪水风险。据此，洪水安全管控区域分为三类：红色区域（禁止建设）、深蓝色区域（满足条件可开展经济类建设）及蓝色区域（满足条件可建设）。

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、福尔热、圣尚昂、多尔多涅河畔蒙索、下巴锡尼亚克、雷亚德、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、阿斯泰亚克与利乌尔德尔。
