Abstract

Climatic factors and human activities can cause mass movements. Due to the risk of these movements to human communities, one has to control them. In order to control mass movements, different aspects of the movements should be studied in detail. The aim of this research is to evaluate the efficiency of a statistical model - LOGISTIC REGRESSION - and a probabilistic model - FREQUENCY RATIO - in ROCKFALL HAZARD MAPPING in THE SALAVATABAD SADDLE in eastern Sanandaj, Iran. The study of 34 sensitive slopes and 34 stable slopes in the study area using field works, local interviews and the literature review showed that 8 factors including slope gradient, slope aspect, slope curvature, elevation above the sea, and distance from road, distance from faults, lithology and landuse are the most effective factors for occurring ROCKFALLs. The relationships of ROCKFALL and these 8 factors were studied by the LOGISTIC REGRESSION model and the probabilistic FREQUENCY RATIO model and the generated ROCKFALL susceptibility maps were compared. The results showed that both models work reasonably well for ROCKFALL hazard studies; however, the LOGISTIC REGRESSION model has an accuracy of 85.09 percent of the Area under ROC Curve (AUC) in prediction of sensitive areas compared to the accuracy of 76.74 percent by the probabilistic FREQUENCY RATIO model. Therefore, the LOGISTIC REGRESSION model can be used for ROCKFALL hazard studies in the study area.
