Considering the dramatic results as life losses and economic damages, landslides are the second most important type of natural hazards in Turkey following the earthquakes. The Western Black Sea region is well known with its frequent landslide events. In this study, Yenice Watershed, which embodies Derebaşı and Cebeciler landslides, was investigated within the context of water effect on landslide susceptibility. The relation between the landslide occurrence and variations in the saturation degree was attempted to be investigated in a watershed scale. In this way, landslide susceptibility variations could be analysed in space and time evolving out of triggering factors as water effect in terms of saturation degree of soil. This study presents an integrated approach which utilize the Soil Moisture Distribution and Routing (SMDR) model and Frequency Ratio Analysis with conventional parameters of landslide susceptibility.
