Percentage of the city that would be flooded in case rivers rise one metre

Methodology

1) Potential flood areas by 1 m water rise were delineated for all Europe according to ETC/LUSI (2010). 2) Cities were defined by clipping UMZs inside Core City of Urban Audit. 3) Resulting layers of step 1 and step 2 were crossed and, for each city (accordign definition in step 2) intersected area was calculated. 4) For each city, flooded area (step 3) was divided by total area (part of the UMZ inside the core city of Urban Audit) in order to obtain the percentage. 5) Percentages obtained from the cities were grouped by quartiles in order to represent groups of cities in the map.

Note: Neither coastal floods nor flood protection measures are considered in the calculations.
