Abstract. Floods in the Mediterranean region are often flash floods, where short and intense precipitation is usually the main driver behind the events. Determining the link between the causes and impacts of floods can help better characterise the level of flood risk. However, up until now limitations in quantitative observations for flood-related damages have been a major obstacle when attempting to analyse flood risk in the Mediterranean. Flood-related insurance damage claims, which could provide a proxy for flood impact and cover the last 20 years, are now available in the Mediterranean region of Catalonia, in northeast Spain. This means a comprehensive analysis of the links between flood drivers and impacts is now possible. The objective of this paper is to analyse the possible relationship between precipitation and flood damage compensation for the period of 1996–2015. Results show high correlation values between daily precipitation and insurance data on a regional, basin and local scale. These results confirm the hypothesis that precipitation is the main contributing factor to damages caused by flash flood events. The relationships between precipitation and damage shown provide insights into the flood risk in the Mediterranean and are promising for supporting flood management strategies.
