Regional issues of the PPRI 2013 Dordogne and tributaries in Hautefage — 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(Dordogne)及其在科雷兹省(Corrèze)欧特法日(Hautefage)的支流区域议题
科雷兹省利乌尔德尔(Liourdres)地区阿尔让塔(Argentat)流域多尔多涅河及其支流的自然洪水风险预防规划(PPRI)方案,覆盖15个市镇。
自然风险规划(PPR)依据《环境法典》第L.562-1条制定。针对风险暴露区域,需结合风险强度划定禁止建设与安装的区域以避免加剧风险;对于可获批建设及安装的区域,则明确相应实施要求。
本多尔多涅河流域及其支流(阿尔让塔至利乌尔德尔段)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)。涉及河道包括多尔多涅河、马罗讷河(Maronne)、苏维涅河(Souvigne)、萨涅河(Sagne)、菲莱尔河(Filèle)、马尔法尔热河(Malefarge)、梅努瓦尔河(Ménoire)以及塞鲁河(Cerou/Céroux)。灾害风险源自模型推演:苏维涅河、萨涅河与菲莱尔河以有记录以来的最强历史洪水(1960年10月洪水)作为参考标准,多尔多涅河、马罗讷河、马尔法尔热河、梅努瓦尔河与塞鲁河则采用百年一遇计算洪水作为参考标准。本规制旨在防范洪水对人员与财产造成的风险,据此将洪水风险区域划分为三类:红色区域(不可建设)、深蓝色区域(可在满足经济活动相关条件下建设)以及蓝色区域(可在满足相关条件下建设)。
各对应市镇的PPRI分别为:多尔多涅河畔阿尔让塔(Argentat-sur-Dordogne)、欧特法日(Hautefage)、拉沙佩勒-圣热罗(La-Chapelle-Saint-Géraud)、福尔热(Forgès)、圣沙芒(Saint-Chamant)、多尔多涅河畔蒙索(Monceaux-sur-Dordogne)、下巴西尼亚克(Bassignac-le-Bas)、雷加德(Reygades)、谢奈耶-马斯谢(Chenaillers-Mascheix)、布里瓦扎克(Brivezac,已与多尔多涅河畔博略合并)、多尔多涅河畔博略(Beaulieu-sur-Dordogne)、诺纳尔(Nonards)、阿尔蒂亚克(Altillac)、阿斯泰亚克(Astaillac)以及利乌尔德尔(Liourdres)。
