Mapping of flooding areas of the Diege in the crossing of Ussel in Corrèze
Municipalities of Saint-Pardoux-le-Vieux, Chaveroche, Ussel, Mestes, Saint-Exupéry-les-Roches
Tables of flooded areas according to their frequency (preferential flow zone — raw return 5 to 15 years- and maximum flooding zone by hydrogeomorphology — exceptional raw-) estimated in relation to the valley morphology for the river La Diège. Tables of hazards, water heights and flow velocities obtained by hydraulic modelling (Hac-Ras model) for the section crossing the urban area of Ussel (low, medium and high speeds; water heights < 0.5 m, between 0.5 m and 1 m and > 1 m; low, medium and strong hazard (cerema 2009 study)
1/10000 for the hydrogeomorphological approach and 1/5000 for the hydraulic approach.

科雷兹省(Corrèze)于塞勒(Ussel)河段的迪耶格河(Diege)洪水区域制图
涉及市镇:圣帕尔杜勒维耶(Saint-Pardoux-le-Vieux)、沙弗罗什(Chaveroche)、于塞勒(Ussel)、梅斯特(Mestes)、圣叙佩尔莱罗什(Saint-Exupéry-les-Roches)
针对拉迪耶格河(La Diège),基于河谷形态估算得到按洪水发生频率分类的洪水区域统计表,分为两类:优先流区——原始重现期5至15年的区域,以及水文地貌学意义上的最大洪水区——极端原始数据区域
针对横穿于塞勒城区的河段,通过水力建模(Hac-Ras模型)计算得到的灾害等级、水深及流速统计表:流速分为低、中、高三档;水深划分为<0.5m、0.5m至1m及>1m三个区间;灾害等级分为低、中、高三级(数据源自CEREMA 2009年研究)
水文地貌学分析采用1/10000比例尺,水力建模分析采用1/5000比例尺
