Abstract:

One of the important natural hazards arising from topographic, morphological and meteorological conditions in Bitlis city in Eastern Turkey is rockfall. As one of the natural hazards, rock falls damage settlements and cause significant loss of life and property. There are many inclined and steep slopes along the Bitlis Stream Valley in the city. The urban and intercity roads were designed parallel to these slopes, while many neighbourhoods of the city have been built on these slopes. The ground snow load also contributes significantly to the rockfall hazard in Bitlis where the highest snowfall was observed in Turkey. In addition to these unfavourable conditions, random structuring was also added, on the other hand, topographic and morphological conditions and the hazard of rockfall were almost never taken into account. The risk of rockfall, which is observed intensely in seven neighbourhoods in Bitlis dontown, was investigated by Fine-Kinney Method within the framework of this study. In the frame of Fine-Kinney Method, Damage probability rating, Hazard exposure frequency rating, Impact rating of hazard on human and environment were calculated and Action planning table was prepared to define the risk of the rockfall in Bitlis downtown.
