In this catalogue, in total, 545 events are reported, which caused 686 casualties and extensive damage across the country. Although regular recording of flood events by civil protection agencies started relatively recently in Greece, an extensive catalogue of flooding phenomena during the last 130 years has been compiled (Diakakis et al.
In the Mediterranean region, flash flooding is the most common type of inundation since the majority of flood events is induced by intense rainfall occurring in short time periods. Rising rate of urbanization, together with high population density, especially in coastal areas, contribute to augmenting flood vulnerability in the region. Finally, the application of both of the above functions to a third case (the Erasinos river basin in Attica, Greece) resulted in a fair difference (9 %) in the estimation of the expected average annual direct damage to residential buildings.Īccording to the Emergency Disasters Database (EM-DAT), between 20 the number of large-scale floods around Southern Europe increased with respect to the previous decade to over 120 major events causing some 345 fatalities and an estimated economic loss of at least €12 billion. Differences and similarities in damage datasets are examined and explained by related causative factors such as structural or architectural features of buildings. The local depth-damage function for residential use is compared to generalized functions and a site-specific function developed for the urban area of Palermo, Italy. The replacement cost of the affected components of a building structure and the market value of each category of flood-affected property are estimated in order to develop depth-damage relationships for building structures. In the case study, the damage percentage is calculated per category of flood-affected property on the basis of relief payments. It also compares the developed depth-damage functions to functions from other areas with similar conditions. This paper aims at demonstrating a step-by-step methodology for devising depth-damage functions using data from a flood event which occurred in Moschato, a suburb of Athens, Greece in July 2002. It still remains an open issue whether a site-specific depth-damage function can be applied to another region with similar climate and building conditions.
However, there are few publications that describe in detail the derivation of depth-damage functions based on actual flood damage data. A conventional approach for the economic estimation of direct flood damage to buildings is using the method of depth-damage functions.
