“…Additionally, these companies are reluctant to provide their databases, and some of them are not even available due to confidentiality restrictions (André et al 2013, CNT 2014. For this reason, there are still few studies that relate flooding and insurance (Merz et al 2004, Thieken et al 2006, André et al 2013, Zhou et al 2013, Spekkers et al 2013a, 2013b, Moncoulon et al 2014, Paudel et al 2015, Torgersen et al 2015, Bernet et al 2017, Grahn and Nyberg 2017, Sörensen and Mobini 2017, Cortès et al 2018).…”

This research aims to understand how insurance, rainfall, land cover and urban flooding are related and how these variables influenced the material damage in the Lisbon Metropolitan Area (LMA) during the 2000-2011 period. Correlation coefficients show strong relationships between built-up areas and claims (0.94) and payouts (0.88). Despite no significant relationships being found between rainfall and the amount of material damage per event, three likelihood levels of flooding were determined for hourly rainfall. Unlike the studied period, the number of claims and their spatial distribution during the 2008 extreme rainfall event were strongly dependent on rainfall. Flooding related to the old watercourses assumed greater importance during this extreme event, recovering a more natural/ancient hydrological behaviour. In the LMA, the greatest material damage was the result of high-magnitude/low-probability rainfall events. Lower magnitude events can trigger numerous claims in heavily built-up areas, but they are hardly capable of producing large material damage.
