Height of the flood zone of the Roanne (2004) in Corrèze

Municipalities of Beynat, Sérilhac, Lanteuil, Albignac, Dampniat

tables of the atlas of the flooding areas of the Roanne by hydrogeomorphological approach (naturalist) outside the area of stakes and supplemented by a more detailed approach allowing to qualify the hazard in the crossing of the village of the commune of Lanteuil

Table of flooded areas according to their estimated frequency (frequent raw return 1 to 5 years; frequent return floods 5 to 15 years; exceptional floods returning > 100 years) in view of the morphology of the valley for the river la Roanne (between the confluence with the Corrèze downstream and the place called “Moulin de Cors” municipality of Beynat upstream) for the sectors without stakes and, for the area at stake (bourg of Lanteuil) table of the qualified hazard after extrapolation for a centennial flood of the profile along the flood of 2001 (calmed on flood marks) (uncertainties: accuracy at a few decimeters) reported on the topography made.

罗讷河（2004年）在科雷兹省（Corrèze）的洪水淹没区高度数据集。
本次覆盖的行政区域包括贝纳（Beynat）、塞里亚克（Sérilhac）、朗特伊（Lanteuil）、阿尔比尼亚克（Albignac）与当普尼亚（Dampniat）共5个市镇。
数据集包含采用水文地貌学（自然主义）研究方法编制的罗讷河洪水淹没区图集表格（不含风险管控区段数据），并补充了针对朗特伊（Lanteuil）公社村庄过境段的精细化分析，以定性表征该区域的洪灾风险。
针对非风险管控区段，结合河谷地貌特征，编制了按预估重现期分类的淹没区表格：1~5年一遇常规洪水、5~15年一遇高频洪水、重现期大于100年的极端洪水，覆盖河段为罗讷河下游与科雷兹河汇流处至上游贝纳（Beynat）镇内名为‘库尔西磨坊（Moulin de Cors）’的区域；针对风险管控区段（朗特伊（Lanteuil）镇区），基于2001年洪水痕迹校准的断面数据（测量精度为几分米，存在不确定性），通过外推百年一遇洪水得到经定性表征的洪灾风险表格，并将其叠加于实测地形之上。
