|The SPEI fulfils the requirements of a drought index since its multi-scalar character enables it to be used by different scientific disciplines to detect, monitor and analyze droughts. Like the sc-PDSI and the SPI, the SPEI can measure drought severity according to its intensity and duration, and can identify the onset and end of drought episodes. The SPEI allows comparison of drought severity through time and space, since it can be calculated over a wide range of climates, as can the SPI. Moreover, Keyantash and Dracup (2002) indicated that drought indices must be statistically robust and easily calculated, and have a clear and comprehensible calculation procedure. All these requirements are met by the SPEI. However, a crucial advantage of the SPEI over other widely used drought indices that consider the effect of PET on drought severity is that its multi-scalar characteristics enable identification of different drought types and impacts in the context of global warming.<br>

Description The European Flood Awareness System provides probabilistic flood forecast information more than 48 hours in advance to National Authorities. It currently incorporates multiple weather forecasts from three different weather services, real-time weather observations from more than 5000 stations across Europe and real-time hydrological stations from more than 500 stations.

EFAS uses LISFLOOD as a hydrological model. LISFLOOD is a GIS-based, distributed hydrological rainfall-runoff-routing model specifically designed to be used in large scale catchments. Detailed information on its specific characteristics and example applications can be found in the User Manual or in various publications. The model is run in EFAS for all of Europe on 5km grid and either with a six-hourly timestep fed by ECMWF deterministic forecasts.
