Analysis of rockfall hazards along NH-15: a case study of Al-Hada road
The analysis results showed the starting falling rock with X (m) and Y (m), the mass of falling rock (kg), first hit point and run out the distance of falling rock. The slope height is more than 15 m in all study locations except site 4, which allows the blocks to attain higher velocity and even higher momentum.
