rates of the FR and WoE methods are in the range of 0.7332–0.7907, indicating a good performance of the models, with a slight differentiation for the WoE model. In the case of the success rates, the IV method shows a low score of 0.5881. This value is less convincing than the two remaining models ( Fig. 5d ).
From these calculations, we can say that the slope gradient is the most important parameter for slope stability analysis, because the driving force of mass movement increases with increasing slope. In the study area, the gradients over than
