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.

Abstract

This article evaluates the implementation status of water supply and sewer systems in Băilești Plain, as a response to the alignment with the objectives of the National Sustainable Development Strategy 2030. The length of the water supply network and the sewer system was analyzed at the administrative-territorial unit (ATU) level and their correlation with the population in each ATU was assessed. The potable water distribution network is approximately 900 km, which is insufficient for the population in the region. Furthermore, the sewer network has a low level of implementation in rural areas, not yet reaching the objectives set by the strategies and Oltenia Water Company (OWC), namely providing access to essential utilities for the population.

The influence of topography on the subsidence processes of loess-like deposits from Sălcuța plain (South-western Romania)

Abstract

This paper aims to establish the role of the local topography of Sălcuța Plain (subdivision of the Oltenia Plain) in the subsidence process of loess-like deposits. The relevant features of the topography, especially the slope, were generated using SAGA GIS v.7.8.0 and QGIS v.3.22 software based on an altimetric terrain model. The results obtained highlight the fact that 303 microdepressions were formed following the chemical and mechanical subsidence of the loess deposits. The most important characteristic, which conditions the genesis of the subsidence process and implicitly the formation of microdepressions, is the slope; in this case, the subsidence process occurs in areas where the slope has values lower than 2 degrees. The research advanced by generating the Topographic Wetness Index (TWI) in order to identify areas with moisture excess, the moistening of loess-like deposits being one of the basic conditions in the genesis of the subsidence process. The highest values of the Topographic Wetness Index (TWI), over 10, were recorded in the areas with microdepressions.
