Short summary

Catastrophic floods (the most severe ones) in Catalonia from 1301 do not show any statistical trend, while extraordinary floods (moderate ones) have increased since 1850 due to a marked increase in developed land and population in small coastal basins. The most significant flood-rich periods occurred with a strong negative NAO phase. Solar activity has some impact on changes in catastrophic floods: flood-rich periods in autumn generally occurred during periods of increased solar activity.
