Abstract:

This study aims to analyze by spatial queries using QGIS technology, the identification of flood risk settlements in Romania, depending on precipitation forecast, which will lead to the achievement of the objectives imposed by the European Union on the reduction of the potential negative effects of the floods for human health, economic activity, the environment and cultural heritage. Firstly, it has been presented the actual stage of the use of geographic information systems, after which it has been analyzed how they can be used in the flood risk assessment on the example of Romania, in order to reduce the negative consequences. The collection of data was done in digital form from three types of maps: Romania's digital map, flood risk map and precipitation forecast map. The spatial data base integrated with graphical information thereby provides a flood risk spatial mapping, which together with analysis of thematic maps leads to a rapid assessment, analysis and visualization of the potential consequences. In this way, decision makers can know and prevent certain poor situations , based on the history and on the images obtained in real time by satellite of the water level of rivers and rainfall. And, during disasters, satellite imagery provides reliable information that fast intervention systems can use to make optimal and real-time decisions.
