25.06.18A multipurpose flood inundation framework for Europe 2
• Physical based
FLOOD MODELLING
• 2D/Floodplain hydraulics see Bates et al., (2010)
1. Digital Elevation Model (DEM)
• 1D/Channel hydraulics see Neal et al., (2012)
1. Channel widths
2. Channel depths
3. Bank heights
4. Inflow boundary conditions (discharge/water
level)

Setup
1. MERIT-DEM (Terrain elevations)
2. HydroSHEDS hydrography at 1 Km
3. Widths from the Global Width Database
for Large Rivers (GWD-LR)
4. Daily discharge between 1994-2014,
JRC Ispra (EFAS System)
5. Sea level from Permanent Service for
Mean Sea Level (PSMSL)

● We are validating the current modelling framework across European basins by
using real flood outlines (from local authorities) and satellite-based outlines
(from MODIS, Landsat) to generate an European flood inundation reanalysis
● This methodology can be applied elsewhere by coupling a different source of
forcing (e.g. National Water Model from NOAA)
● Once calibrated the modelling framework, different applications can be
achieved (e.g. Early warning system, climate change scenarios, flood risk
mapping)
