Summary:
The purpose of the present thesis is to study the phenomenon of flash floods and specifically to study the area of Mandra in western Attica, which was once more affected by an instantaneous flood that cost the lives of 23 people, as well as the study of the location of an early warning system with capabilities and innovations that until now have been limited in the field of disaster management. The history of this area and the frequency of such weather events in the wider area make the study necessary to avoid similar events of any scale. For the realization of the work measurements (height of water level) were carried out by the research team of the postgraduate program in the area where the destruction occurred as well as digital ground and surface models (DEM, DSM) provided by the research team. The analysis, processing and extraction of results was carried out using the GIS and in particular the ArcGIS Desktop - Arc Map (ESRI) and the SANET tool created by Professor Atsu Okabe and his team from the Aoyama Gakuin University in Tokyo, Japan, through which I was able to map out the flood risk of the area. Then, taking into account the field data, maps and theoretical background from the bibliography, the final map was created, depicting the scheduling of an early warning and tracking system (CPS) that interacts between the physical and the digital world.
