Flood hazard analysis - GIS aspects of possible solution

Abstract

© by PSP. Floods are a devastating natural hazard that affect more and more people every year, so flood hazard analysis is becoming increasingly necessary. For the purpose of this paper, floods that affected a large area of Southeastern and Central Europe in mid-May 2014 were analyzed using available hydrological measurements, satellite and information technologies. The research involves flood hazard analysis in Serbia and Croatia, mainly focusing on zones of influence and changes in the water level of Sava River and satellite image verification. For that purpose GIS techniques have been used -mostly the free GIS program and multi spectral Landsat images. The same area was analyzed before the floods on 19 May 2013 and after the floods on 22 May 2014. Using GIS techniques for flood hazard analysis and timely monitoring of fluctuations in water levels may be beneficial in the improvement of early warning systems and the prediction of flooding risks, and provide greater protection for human settlements.
