N_ZONE_ALEA_PPRN_20100005_S_019 Classes of the hazard (obtained by crossing heights and speeds) of the PPRI 2013 Dordogne and tributaries to Beaulieu sur Dordogne — 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.

N_ZONE_ALEA_PPRN_20100005_S_019 2013年科雷兹省多尔多涅河及其通往多尔多涅河畔博略(Beaulieu-sur-Dordogne)的支流防洪风险规划(Plan de Prévention des Risques d'Inondation,PPRI)的灾害等级,灾害等级通过水位与流速交叉分析得到 科雷兹省利乌尔德尔(Liourdres)境内覆盖阿尔让塔(Argentat)片区的多尔多涅流域及其支流的自然洪水风险预防规划(PPRI),共涉及15个市镇 自然防洪风险规划(Plan de Prévention des Risques naturels,PPR)的制定需符合《环境法典》第L.562-1条之规定。在风险暴露区域,规划将根据风险强度划定两类管控区域:一类为禁止建设与安装设施的禁区,以避免加剧灾害风险;另一类为可经审批开展建设与安装活动的合规区域,此类区域需明确落地实施的具体要求 本次针对多尔多涅流域及其从阿尔让塔到利乌尔德尔的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,每个市镇对应一项专属PPRI。涉及的河流包括多尔多涅河(Dordogne)、马罗讷河(Maronne)、苏维涅河(Souvigne)、萨涅河(Sagne)、菲勒勒河(Filèle)、马勒法尔热河(Malefarge)、梅努瓦尔河(Ménoire)以及塞鲁河(Cerou)。灾害等级由数值模拟推演得出。参考洪水标准分为两类:苏维涅河、萨涅河与菲德勒河采用1960年10月有记录以来的最强洪水事件作为参考;多尔多涅河、马罗讷河、马勒法尔热河、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。本规划的规制目的为防范洪水对人员与财产造成的风险。为此,洪水风险管控区域被划分为三类:红色区域(禁止建设)、深蓝色区域(可在满足经济活动相关要求的前提下建设)以及蓝色区域(可在满足相关条件的前提下建设) 15个对应市镇分别制定了专属PPRI,具体包括:多尔多涅河畔阿尔让塔(Argentat-sur-Dordogne)、奥特法日(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)、下巴尼亚克(Bassignac-le-Bas)、雷加德(Reygades)、谢奈耶-马谢(Chenaillers-Mascheix)、布里夫扎克(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)
