| Zusammenfassung |
| In this paper the catastrophic and extraordinary floods occurring in
Barcelona County (Catalonia, NE Spain) are studied, in order to characterise
the temporal evolution of extreme flash floods in that area and their main
features. These events usually cause economical losses and major problems
for undertaking daily activity in Barcelona city. This kind of floods is a
very common feature in the North-east of Spain and they are recorded every
year in some point of Catalonia. This contribution also shows the frequency
of those events, within the framework of all the floods that have occurred
in Barcelona since the 14th century, but also describes the flooded area,
urban evolution, impacts and the weather conditions for any of most severe
events. The evolution of flood occurrence shows the existence of
oscillations in the earlier and later modern age periods that can be
attributed to climatic variability, evolution of the perception threshold
and changes in vulnerability. A great increase of vulnerability can be
assumed for the period 1850-1900. The analysis of the time evolution for
the Barcelona rainfall series (1854-2000) shows that no trend exists,
although, due to the changes in urban planning, flash-floods impact has
changed over this time. The number of catastrophic flash floods has
diminished, although the extraordinary ones have increased. |
