ERIC flash flood indicator

EFAS holds two flash flood indicators: ERIC and ERICHA. The ERIC flash flood indicator data set holds two layers. The one layer contains key locations at which the ERIC flash flood indicator forecasts a high probability of exceeding the 5-/20-year return period. For those locations additional hydrological information are provided. The second layer outlines the drainage area affected by heavy precipitation and potential flash floods.

This information is part of the operational suit of EFAS (www.efas.eu) and intends to provide EFAS partners with in-depth information at relevant key locations along affected European rivers to facilitate decision making.

The update frequency of this data set is twice a day (00:00 and 12:00 UTC); and the spatial coverage is the extended geographic Europe.

EFAS 拥有两类山洪预警指标：ERIC 与 ERICHA。其中 ERIC 山洪预警指标数据集包含两个图层：其一标注了 ERIC 系统预判出洪水超5年/20年一遇重现期概率较高的关键点位，并为这些点位补充了相关水文信息；其二则勾勒出受强降雨及潜在山洪影响的汇水区域。
本数据集隶属于 EFAS 业务套件（www.efas.eu），旨在为 EFAS 合作伙伴提供受影响欧洲河流沿线关键点位的深度信息，助力决策制定。
该数据集每日更新两次（协调世界时00:00与12:00 UTC），空间覆盖范围为扩展后的欧洲地理区域。
