Abstract

The paper examines the exceptional floods that appeared within the Raznic river basin, more specifically, their amplitude, causes, and consequences. In order to accomplish the objectives, hydrological data were used to identify the characteristics of flash floods recorded in the years 1972, 2006 and 2023. Finally, the inventory of the socio-economic damages recorded led to the analysis of structural and non-structural measures proposed and implemented by local authorities. The research offers an insight on the dimension of the maximum discharges recorded during exceptional floods (1972 – 190 cm/s; 2006 – 188 cm/s; 2023 – 210 cm/s), their frequency and return period. The importance of the study lies in the fact that it manages to revive both the insufficient scientific and stakeholder concerns on this kind of hydrological risk, issued in a small catchment, considering their recorded effects and the high frequency of occurrence.

Extreme hydrological phenomena in the hydrographical basin of the Danube. The floods from the spring of 2006 along the Oltenian sector of the river

Abstract: Among the natural hazards that confront the human civilisation and its activities, floods represent hydro-meteorological phenomena with high frequency and with destructive effects, both in the economic and in the social sectors.
The Oltenian sector of the Danube Floodplain develops between Drobeta-Turnu Severin and Corabia, being 335 kilometres long and covering a surface of about 105 thousand hectares, which represents around 1/5 of the entire surface of the floodplain displayed by the Danube on the Romanian territory. Under the conditions of this geographical space, the Danube Floodplain presents high vulnerability.
It is necessary to explain the somewhat differentiated flooding of the Oltenian sector of the Danube Floodplain on the two sub-sectors: the one stretching between Drobeta-Turnu Severin and Golenţi – Calafat, as compared to the other, which extends downstream of Calafat, all the way to Corabia and Islaz. Also, it is important to show the reasons that led to the flooding of certain human settlements located within the southern sub-sector, on the morphological levels offered by the low and inferior terraces of the Danube, respectively the settlements that exist between Rast and the confluence between the Olt and the Danube rivers. Finally, taking into account the stipulations of the new National Strategy for Risk Management, we shall formulate certain recommendation to increase the resilience of the area to flood phenomena.
