Flash flood layers

EFAS is also providing information on flash floods. This can be found in the Flash Flood menu and particularly after selecting the ERIC reporting points layer.

The ERIC reporting points layer indicating probabilities for flash flooding.


Note that the information about flash flooding can also be presented as maps showing the affected area (see example below).

Image Added

The affected area based on the ERIC values (flash flooding).


For the ERIC reporting points, the number placed near the triangle indicates the % of COSMO-LEPS members (20 in total) exceeding the 5-year return period threshold. The triangles can have different colour and size depending on the (probability of the) threshold exceedance and lead time. More information on the ERIC points is available here. Information about the scientific evaluation of the ERIC product can be found here.

Static layers

The static layers menue contains mostly auxiliary layers easing vizualisation and interpretation of the information presented in the EFAS IS. For example, the LISFLOOD drainage network and the Catchments layer presented together with the Major Rivers layer allow for a better orientation on the map.
