Rockfalls are one of the major hazards in hilly regions which can impose significant damages to the structures as well as human lives and property. Understanding the behavior of a rockfall along its trajectory is essential in order to design and implement protection measures for providing safe environment. Coefficient of restitution is one of the most important parameters for predicting a rockfall behavior. Back analysis is an effective tool in estimating the coefficient of restitution for a specific area. This study presents the analysis of rockfalls around the Mardin castle by probabilistic methods after estimating the real coefficient of restitution. Run out distance, bounce height, kinetic energy and translation velocity are studied in the area and accordingly barriers in 4 m height with capacities ranging from 3000 to 5000 KJ are suggested as protective measures.
