Investigating the flooding events of the urban regions of glyfada and voula, attica, greece: a contribution to urban geomorphology

Urban geomorphology examines the conditions that lead to flooding problems in urban regions. Glyfada and Voula are located on the southwestern coast of Attica. Several times in the past catastrophic flooding events have taken place in these areas. This paper concerns the geologic and geomorphologic features, human intervention and its impact, along with their interaction. The locations with the highest vulnerability to flooding were registered. GIS processing served to present the results of this investigation. The relief of the region, the geologic and geomorphologic conditions, the stream flow features, the drying up of wetlands and lagoons, the elimination of vegetation cover, the urbanization of streams and the deficient draining networks, are the main causes of flooding generation in the study area. Some major suggestions dealing effectively with the problem are given.
