Abstract: – The landslides characterization based on physical parameters of the soil from Copăceni village (Cluj county, Romania) – causes, effects and technical measures for rehabilitation. The study area, located 25 km south from Cluj-Napoca city and 7 km north from Turda city, in Copăceni locality, near the Transylvania Highway, is threatened by the landslides, actives or susceptible to be reactivate. The main factors causing the landslides are both natural (as slope morphology, soil features or rainfalls) and anthropogenic (overgrazing, highway construction). Field observations and measurements together with determination of physical parameters of the soil have been conducted in three different points, in order to describe the landslides characteristics, to identify the causes producing the landslides, their effects on environment and humans, and to offer solutions for rehabilitation of the studied area. Thus, the studied landslides are considered as being superficial, shallow and active. The sliding surface is situated at 1.60 meters deep. Small water accumulations can be observed in the lowland areas, resulting marshes zones, present even during the dry periods. The overgrazing is the main identified cause producing the landslides. Due to the fact that these landslides can affect the houses, the gardens, the agricultural areas situated in the vicinity, the road between Copăceni and Săndulești, as well as the Transylvania Highway, some prevention and control measures are necessary.
