Isocotes from the flood zone of the Roanne (2004) — 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.

2004年罗讷河洪水淹没区洪水等值线（Isocotes）数据集—— 科雷兹省
覆盖贝纳（Beynat）、塞里亚克（Sérilhac）、朗特伊（Lanteuil）、阿尔比尼亚克（Albignac）、达姆尼阿（Dampniat）等市镇
本数据集包含采用水文地貌学（hydrogeomorphological）自然实地观测方法编制的罗讷河非设防区域洪水淹没区图集表格，并补充了针对朗特伊市镇村庄河段的精细化灾害风险量化方法
针对非设防区域，本数据集提供结合河谷地形特征、按预估重现期分类的罗讷河淹没区表格：1~5年一遇为高频洪水、5~15年一遇为常遇洪水、重现期超100年为极端洪水；该河段覆盖范围为下游至与科雷兹河汇流处、上游至贝纳市镇境内的科尔斯磨坊（Moulin de Cors）区域。针对设防区域（朗特伊镇区），则基于2001年洪水痕迹校准后的河道断面，通过百年一遇洪水推求得到量化灾害风险表格；该地形数据的精度误差为几分米。
