Abstract

The objective of this paper is the flood risk analysis for the locality of Baltenii de Sus in the Danube Delta using two methods of analysis. This analysis is based on flow and level measurements both on the Danube and near the analyzed locality. The first method consists of modeling a real scenario of a rupture in the protection dam that surrounds the locality, for a period of 1 day using several flooding stages. The second method consists of GIS analysis, namely the application of the maximum water level over the digital terrain model. The digital terrain model is the information base for this study and is used as the main object in order to apply the 2 methods. The results are in the form of flood hazard maps and digital maps with flooded surfaces of Baltenii de Sus locality. Floods caused by the Danube’s peak levels or dam failure can be analyzed through a combination of 1D2D and GIS analysis techniques.
