Abstract

The paper presents some elements of intergated approach in rockfall risk analyses prepared for zone of Macedonian village Staro selo in Polog area. The wider zone of Polog is characterized with pronounced rockfall, landslide and flood hazards in general terms, where several critical locations exists. The results from rockfall simulation analyses, contemporary and innovative terrain surveying techniques used in detection of hazardous zones with LIDAR and INSAR methods and other data are presented. Analyses confirmed the possibility for detachment of rockfalls, which is observed in reality, and not only in the exact zone of the village. Integrating findings from rockfall simulations with benefit and cost analysis of suggested protection mesaures, some recomendations from the aspect of tolerable level of risks including possible trends suggested in new Eurocode 7 generation are presented. The main findings leads to the conclusion, that interaction and integration of technical, economic and social aspects and involving different perpectives is necesary in process of rockfall risk management.
