Flood Risk Analysis Model in the Village of St. George/Danube Delta. Although the natural hazards are currently a main subject of interest on a global scale, a unitary methodological approach has yet to be developed. In most cases, the risk analysis focuses only on an assessment of the probable material damage resulted from a specific risk scenario. Taking these matters into consideration, the aim of this study is to develop an efficient flood risk assessment methodology based on the example of the village of St. George in the Danube Delta. The study area is situated at the mouth of the St. George river branch, being part of the largest ecosystem of the European humid zones. As a complex hydrological process, the flooding of the delta space is very important within the dynamics and evolution of the natural system. The methodology was based on correlations between the flood risk maps resulted with satellite pictures, cadastral plans and field data by using GIS functions, this cartographic material playing an important part in the development of a proper public awareness strategy. In addition, the field investigations conducted in September 2008 focused on collecting the data necessary in the assessment of the buildings. The observations that synthesize the features of each construction included in the analysis were also stored in ArcGis in the shape of a table of attributes. The analysis revealed an increased degree of the area visibility, pointing out not only certain sectors affected by floods, but also the more detailed level of the residences. The flood risk damage assessment potential was also considered for the residences, the model revealing water depth maps. This cartographic material is essential in establishing a series of adequate strategies for the protection of the population and material goods.
