| Abstract | ||
| This study includes the implementation of a method for the analysis of rockfall hazard along roads and motorways. The method is the Rockfall Hazard Rating System (RHRS) developed by the Oregon State Highway Division. This method was implemented on rock cuts along Mirawa main road, north of Shaqlawa summer resort, in Kurdistan Region, north Iraq. Seven road cuts are rated according to RHRS and the results showed that most of the studied rock cuts of Mirawa area are classified as moderate hazard and needs remedial measures with moderate urgency, because their rockfall hazard rating values are between 300 – 500. The other two rock cuts (Sites 1 and 6) are classified with low hazard and needs remedial measures with low urgency, because their RHR values are less than 300. Accordingly, a geological map with rockfall hazard sites was prepared for Mirawa main road. | ||
