Abstract

According to Copernicus climate change service (C3S), the summer of 2024 was the warmest on record for our continent, the average surface air temperature over the European land reaching +1.54°C above the 1991-2020 average. In Romania, extremely high temperatures were recorded in July and August, heatwaves affecting particularly the southern part of the country. However, at their peak, western and eastern extra-Carpathian regions also registered extremely high temperatures. In Oltenia, there were recorded 24 daily maximum temperatures ≥40°C (20 in July and 4 in August), the area located in the proximity of the Danube being the most exposed (15 values above 40°C). In July, in four county municipalities (Drobeta-Turnu Severin, Craiova, Târgu Jiu, and Râmnicu Vâlcea), there were recorded 13 consecutive days with maximum temperatures above 35°C, while at Slatina there were 14 days (July 7/8 – July 20). In August, the interval was shorter, between 7 days at Craiova and 10 days at Drobeta-Turnu Severin (August 10/11 – August 17/18). The persistence of high atmospheric pressure formations intensified local insolation processes, which, together with tropical air advections, contributed to the increase of heating. Even if the previous thermal records (registered on July 24, 2007) were not exceeded, in terms of average temperature, the summer of 2024 was hotter than the summers of 2007 and 2012 (values above 27°C were registered at six meterological stations in July and at five in August), which triggered numerous problems in the region – agricultural losses, wildfires, power shortages, health issues.

EXCEPTIONAL FLOODS ON THE RAZNIC RIVER (SOUTH- WESTERN ROMANIA)

Oana MITITELU-IONUȘ Daniel SIMULESCU Ioana PĂTRĂȘINCĂ-GEAMBAȘU 10.52846/AUCSG.25.02 10.52846/AUCSG.25.02

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.

GEOMORPHOLOGICAL RISK AND VULNERABILITY OF THE SUBCARPATHIAN AND PIEDMONT SECTORS OF THE GILORT RIVER BASIN

Emil MARINESCU Sidonia MARINESCU 10.52846/AUCSG.25.03 10.52846/AUCSG.25.03

Abstract

Currently, geomorphological studies have been tasked with investigating a large part of natural hazards, so any study should end with a geomorphological risk map. The geomorphological risk maps take into account the analytical and synthetic integration of as many variables as possible to target both natural and social elements. In approaching the geomorphological risk assessment methodology, it is necessary to correlate each control factor with the map of current geomorphological processes and establish its weight of influence. A layer was created for each variable and the current processes were quantified by means of another layer by using Spatial Analyst – Density (ArcGIS). From the obtained layers, the numerical information was extracted according to a grid network, adopting a convenient size of the grid cell. Considering the dynamics of the current processes in the Subcarpathian and the Piedmont sector of the Gilort hydrographic basin (Romania), the geomorphological risk map was created for this space, highlighting four categories of risk (very low, low, medium and high). The obtained map has an important practical utility and includes the degree of vulnerability of the anthropogenic component to certain types of natural hazards.

ALIEN FLORA FROM DOLJ COUNTY, ROMANIA

Daniel RĂDUȚOIU Ioana SIMION Violeta BORUZ 10.52846/AUCSG.25.04 10.52846/AUCSG.25.04

Abstract

The areas covered by alien plants in Europe have expanded during recent years. Romania ranks 17th out of all European countries, with 740 allochthonous species. Most of these plants are classified as neophytes (703), the rest being archaeophytes (23), or archaeophyte-neophytes (14). The analysis of alien plants on the territory of Dolj County led to the identification of 160 taxa that belong to 49 botanical families. The best represented family is Asteraceae, with 30 taxa. There is a significant gap between the family holding the first position and the following two, i.e., Amaranthaceae, with 11 taxa and Fabaceae, with 10 taxa. Even though almost half of the families with identified alien plant species have only one representative, the reality in the field shows a completely different image, as the populations of the respective taxon are abundant (e.g., Phytolacca americana, Ailanthus altissima, Acer negundo, Asclepias syriaca, etc.). The analysis of the plant inventory revealed the presence of certain invasive taxa (Ambrosia artemisiifolia, Erigeron canadensis, Vallisneria spiralis, Erigeron annuus, Robinia pseudacacia), which found good development conditions on the territory of Dolj County. Some of them are of interest to the European Union (Asclepias syriaca, Ailanthus altissima, Elodea nuttallii). Climate changes occurred during recent years, associated with human activities in all domains, have led to obvious transformations in the chorology of some alien species on the territory of Dolj County. Xerophilous, thermophilic, heliophilous, and anthropophilic species (e.g., Abutilon theophrasti) are favoured.

A BRIEF HISTORY OF EUROPEAN CHRISTMAS MARKETS. CASE STUDY: THE CITY OF CRAIOVA (2020-2024)

Alexandra-Lucia ZAHARIA Claudia-Daniela ALBĂ 10.52846/AUCSG.25.05 10.52846/AUCSG.25.05

Abstract

The study «A brief history of European Christmas Markets. Case Study: The City of Craiova (2020-2024)» aims to present a brief history of Christmas markets in Europe and to identify how these seasonal events have become, in recent years, a real entertainment industrie, with application on the Craiova Christmas Market. The Christmas markets began to appear in the early Middle Ages for economic reasons: in winter, the food merchants recorded modest sales and began to sell their products near churches, where residents met for Christmas services. The meat sellers were joined by the pastry shops, the confectioners, the toy manufacturers, the ornaments producers, etc. The authorities encouraged and regulated these markets, established the venues, the period, the objects that can be sold. The locals were joined by visitors from other localities, which contributed to the increase in income from these events. At the end of the 19th century, in the Germanic space, the cradle of Christmas markets and the promoter of the decorated tree, the Christmas markets were increasingly numerous and the period of their holding was extended. In the following century, also in Germany, the use of luminous decorations, the specific music, the aromas of mulled wine and gingerbread was imposed, which contributed to the creation of the “Christmas atmosphere”, much exploited commercially today. The Craiova Christmas Market began to become a symbol of the city every winter season. The organizers aim every year to exceed their limits in terms of elements of novelty and uniqueness, to bring to the attention of the public varied themes that would attract tourists of all ages, from all social categories and even from abroad. The visibility of the event has increased year by year thanks to intense promotion on radio and television, the written press, but also on Facebook, Instagram or TikTok platforms.

WATER SUPPLY AND SEWAGE SYSTEM WITHIN BĂILEȘTI PLAIN

Lavinia CRIȘU Andreea-Gabriela ZAMFIR Daniel-Alin SIMULESCU 10.52846/AUCSG.25.06 10.52846/AUCSG.25.06

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.
