Paper Abstract

The main aim of the presented research is to demonstrate an integrated methodology for flood monitoring with SAR and optical satellite data in order to track the dynamics of flooded areas in two different locations in Greece and Turkey. The subjects of the research are the flooded areas near Athens on 12 and 13 November, 2017 and along the valley of the Maritsa River between Greece and Turkey on 17/07/2017. The objects were analyzed and mapped according to ESA (European Space Agency) data from Sentinel. Results have been obtained for quantitative changes of flooded areas and their dynamics. The importance of this type of remote sensing is considerable as the access to the Earth is difficult, and the presence of clouds severely limits research by optical sensors. The use of Synthetic Aperture Radar (SAR) is much more effective, and it is more accurate to plot the flooding degree during flooding and after this event. The data used are with high time-spatial resolution, which is imperative when studying a short-term event such as the flood. River-type floods in combination with torrential rains falling over vast river basin territories such as these two floods on absolutely different seasons are one of the most common natural disasters which cause many economic losses and take many victims. The flood near Athens has taken a few lives and caused great economic damage during the late autumn, which has led to even more complicated situation. The floods along the Maritsa River valley are often repeated.
