ABSTRACT. – Delimitation of Risk Generating Geomorphological Processes in Cluj’s Metropolitan Area. The geological substrate, chemical and physical processes, epigenetic movements, the great diversity of landforms from Cluj metropolitan area are all conditioned by its location at the intercourse of three geographical units (Apuseni Mountains, The Someş Plateau and The Transylvanian Plain); moreover, the climatic conditions are influencing the intensity of the erosion processes and also the type and density of the vegetation which is installed in certain conditions of linear and local erosion. The identification and localization of geomorphologic processes plays an important role in drawing, designing, developing and implementing the local, regional and national development strategies. Once the geomorphologic processes are identified, the next step is to execute risk maps, which are essential in urbanism studies and territorial planning, since on their bases the next direction of town expansion, localization of economical implements, (interdictions, conditionings), real estate investments, transportation networks etc. will be drawn. The research was focused on identifying contemporaneous geomorphologic processes from Cluj metropolitan area and their repartition in the territory. Risk generator geomorphologic processes from Cluj metropolitan area are landslides, torrential bodies, ravines and areas of instability.
