Abstract
There is a high consensus that severe rainfall events in recent years contribute to flood occurrence in the urban environment within Athens basin, Central Greece. Adverse weather conditions that are more frequent in the Anthropocene Period drive extended damage in urban agglomerations, especially to public and private infrastructure, even loss of life. In the previous decade, three rainfall events caused significant impact in the area, resulted in more than one hundred flooded properties. The objective of this work is to analyze these flood events from a meteorological perspective and also their relative impact on urban environment. On the one hand, synoptic meteorological conditions of these events are investigated based on the available rain gauge records, SYNOP reports and composite mean and anomalies of surface and upper-air synoptic patterns. On the other hand, the corresponding impact is analyzed taking into account the entire dataset of flood events on residential property, to provide an overview on several characteristics that determined by utilizing street view imagery and GIS techniques and to highlight the level of differentiation found in the urban fabric. The findings of the analysis give evidence that urban flooding is a result of intense urbanization in synergy with heavy rain of convective structure triggered by atmospheric circulation.
