The dataset contains flood surfaces established by hydrogeomorphological methods in Lorraine

In Lorraine when they were produced.

** Hydrogeomorphological flood: Maximum flooding area defined by the study of fluviatile hydrosystems. The demarcated area includes the minor bed, the major bed and the exceptional major bed of the watercourse. It corresponds to the flooding field of exceptional floods.

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.

本数据集收录了在洛林（Lorraine）地区通过水文地貌方法划定的洪水淹没范围，其生成于洛林地区。

**水文地貌洪水（Hydrogeomorphological flood）：通过河流水系研究确定的最大洪水淹没范围。其划定范围涵盖河道的枯水河槽、主河槽以及特大洪水对应的超主河槽区域，对应特大洪水的淹没场域。

**逐字说明：洪水分区图集包含三类分区：模拟百年一遇洪水范围、水文地貌方法得到的淹没范围、历史洪水范围。后一类分区通过多种方法生成，因此具有不同的内涵。对上述数据进行任何使用或可视化呈现时，均需明确区分不同的分区类型。

依据《洪水指令》生成的大洪水风险区域（Large Flood Risk Territories, HRT）相关数据，未被纳入此前生成的洪水危险区图集（Flood Hazardous Area Atlas, AZI）的现有数据中，需将其补充纳入该图集以完善其内容。
