This study aims to enhance the morphometric analysis of terrain and land classification in Romania's coastal basins through the advanced application of Digital Elevation Models (DEMs). While DEMs are increasingly utilized worldwide for environmental mapping and analysis, their application in the Romanian context, especially for detailed geomorphological studies including flow accumulation, sink routes, and landform classification, remains underexplored. Utilizing DEMs, this research integrates Geographic Information System (GIS) technologies with statistical analyses to investigate geomorphological features such as watershed basins, specific catchment areas, the topographic position index, LS factor, plan curvature, and the topographic wetness index. Results demonstrate the effectiveness of DEMs in identifying complex terrain features and in classifying land with high accuracy, highlighting the utility of incorporating advanced morphometric parameters like geomorphons and flow directions. However, the study acknowledges limitations related to the resolution of DEMs and the necessity for ground verification. The findings have significant implications for environmental management, urban planning, and conservation, offering new insights for land use planning and disaster risk reduction in coastal regions. The relevance of this research lie in its targeted application of DEMs to the complex terrain of Romania's coastal basin, contributing significantly to the field of geomorphology by offering nuanced insights and practical methodologies for terrain analysis and land classification.
