Map Viewing Service (WMS) of the dataset: Modelled centenal flood of the main rivers of Lorraine and the administrative district of Rhin-Meuse basin

The dataset contains the modelled centennial flood envelope of the main rivers of Lorraine and the administrative district of Rhin-Meuse basin.

In Lorraine and on the administrative district of the Rhine-Meuse basin when they were produced.

** Modelled centennial flood: Area exposed to the theoretical flood calculated from the analysis of past floods and which has a per cent chance to occur each year. It can also be said that the centennial flood occurs on average ten times per millennium. On the Moselle stream, the modelled flood of 1947 was represented in the modelled centennial flood layer because its return period is more than 100 years.

VERBATIM:
The flood zone atlas consists of three types of zoning: (the modelled centennial flood,the surface obtained by the hydrogeomorphological method, historical floods. The latter result from different methods and therefore have a different meaning. Any exploitation or representation of these data must be made knowingly with a distinction between the different zonings.

Data produced on the Large Flood Risk Territories (HRT) under the Flood Directive have not been added to previously produced Flood Hazardous Area Atlas (AZI) data. They should be added to supplement the AZI.

本数据集涵盖洛林地区及莱茵-默斯（Rhin-Meuse）流域行政区内主要河流的百年一遇洪水模拟包络线。
本数据集的生成范围覆盖洛林地区及莱茵-默斯流域行政区全域。

**百年一遇洪水模拟：指基于历史洪水分析计算得到的理论洪水影响范围，该洪水每年发生概率为1%。换言之，百年一遇洪水的平均重现期为千年十次。在摩泽尔河（Moselle）河段，1947年的模拟洪水被纳入百年一遇洪水模拟图层中，因其重现期超过100年。**

以下为逐字照录内容：
本洪水区域图集包含三类分区：百年一遇洪水模拟区、水文地貌法圈定的淹没范围及历史洪水区。后两类分区基于不同方法生成，因此含义各不相同。对本数据集的任何使用或展示，均需明确知晓不同分区的差异并加以区分。

根据《洪水指令》（Flood Directive）生成的大洪水风险区域（Large Flood Risk Territories, HRT）数据，尚未被纳入此前编制的洪水危险区域图集（Flood Hazardous Area Atlas, AZI）中，需补充至该图集以完善其内容。
