Abstract

© 2021, Saudi Society for Geosciences.Slope movements are commonly occurring natural disasters damaging the infrastructures, upper structures, and nature. Among the slope movements, landslide is the most damaging and frequent natural disaster. This study investigates the previously occurring slope instability and runs a landslide susceptibility analysis for the Karabük-Yenice area in NW of Turkey. Types of slope movements in the area were mainly slide, flow, and fall type failures. The most frequent slope movements were slides and flows. Fall type of movement, however, was seen only in two locations in bedrock as rock falls. After the determination of the mass movements, landslide susceptibility analysis was performed for the study area. Four predisposing parameters, geology, slope, aspect, and distance to the river were used in the frequency ratio landslide susceptibility analysis. Geographical information system (GIS) and frequency ratio methods were used in landslide susceptibility analysis. GIS made it easy to prepare the required layers and to perform analysis for generating a landslide susceptibility map. The outcome of this study, the landslide susceptibility map, reveals the susceptibility in five classes, namely, very low, low, moderate, high, and very high. The locations of the previous landslides defined by the fieldwork were overlaid on the landslide susceptibility map to verify the validity of the susceptibility analysis and make evaluations and interpretations.
