Hydrological Risk Phenomena and Flood Analysis

Abstract

This paper is one detailed research of the major river basins of the Romanian North Dobrogea, Taita River Catchment. The Taita River has a catchment size of about 591 km 2 and is flowing into the Black Sea through Topraichioi Lake after 57 km. Upstream it has an elevation about 240 m height and 0 m at downstream (the reference is the Black Sea). The complexity of this research study is given, on the one hand, by the descriptive side of the natural aspects (geological, morphological, climatic aspects, hydrology and the soil) and, on the other hand, by the practical side, boosted by the information system processing of data. This study presents the theoretical concepts concerning the hazards and the risk, which, for a better interpretation of the impact of these phenomena, are supplemented by the maps, graphs and photographs.
