It is well known that atmospheric aerosols have both a direct and an indirect impact on the Earth's systems and have natural or anthropogenic origins. In this paper we present the results of the 2022 spring-time lidar measurements conducted within the European Aerosol Research Lidar Network (EARLINET) using a multi-wavelength Raman and depolarization LIDAR system operated in Cluj-Napoca, Romania. The Cluj-Napoca lidar system (CLOP) emission is based on a Nd-YAG laser Continuum INLITE II-30, which has a repetition ...

In recent years, the growing impact of flood events on society, economy and environment, has increased the need for early prevention and mitigation measures. The prediction of future flooding areas represents an important tool that can reduce the magnitude of consequences, by identifying and mapping the flood prone-areas. The intensity and extension of floods depends on various contributing parameters, such as hydrometeorological and geomorphological indicators, land use, anthropic activities. Therefore, by analys...

The population and economy growth in the past years, and subsequently the increased demand for freshwater, led to an increased pressure on water resources. The quality of surface water is affected by anthropogenic factors, such as: domestic sewage, industrial activities, agricultural activities, recreational activities, land use change, urbanization. Therefore, the impact on surface water vulnerability is higher in large urban areas or in urban areas with intense touristic activities. The analysis of water vulnera...

In this paper we present a case study regarding a desert dust intrusion over Central and Eastern Europe in 5th of April 2021, observed using a multi-wavelength Raman and depolarization LIDAR system operated in Cluj-Napoca, Romania. This type of system meets the requirements of the European Aerosol Research Lidar Network – EARLINET and is suitable to provide reliable data on optical parameters for aerosol characterization. While mineral aerosols are the second largest source of aerosol and are the subject of long r...

The devastating impact of floods in the past years triggered the awareness and interest regarding the need of effective flood risk management and improved strategies. The spatial distribution of the elements at risk, which are represented by land use inventories, is an important factor that influence the cost associated with floods, the rapid urbanization leading to an increased flood exposure and vulnerability. The land use planning can be a useful tool for flood damage mitigation and must be taken into account i...

Vulnerability, land use and sustainability are some of the main elements of major concern in the last decades that can be translated in practice through efficient development and planning. The role land use plays is recognized worldwide due to the rapid and continuous urban growth and development, which determine the occurrence of new powerful forces leading to social, demographical, environmental, technological and governmental changes. The large number of disasters in recent years demonstrated that the most effe...

Romanian economy is based, to a certain extent, on chemical industry and its approximately 300 SEVESO operators present on its territory. This situation implies numerous transports of raw materials or final products between operators in the chemical industry and/or other economic entities. A considerable number of cargos may consist in actual shipments of hazardous materials (HAZMAT), fact that can lead to an important issue: in Romania, a developing country, the current road transport infrastructure for dangerous...
