Anthropogenic imprints, including hydromorphological pressure and illegal land use through unauthorised dumping and wastewater discharge, are various forms of human activity that often have lasting impacts on the natural environment. Despite this, integrating them into ecological assessments and water and natural resource management remains underexplored at the river basin scale. This study aims to investigate and analyse illegal dumping and pressures on freshwater resources in the Chepinska and Chepelarska River ...

Rock glacier hydrology remains poorly constrained in marginal permafrost environments such as the Southern Carpathians. This study quantifies spatial variability by relating spring temperatures to elevation, aspect, lithology, and spring type, and temporal variability through diurnal and seasonal thermal amplitudes, to detect permafrost occurrence and assess its influence on alpine groundwater systems. Between 2020 and 2025, 62 alpine springs were systematically monitored in the highest sector of the Retezat Mount...
