GIS-based landslide susceptibility assessment: a case study in Kelemen Valley (Yenice—Karabuk, NW Turkey)

摘要: This study focuses on revealing the landslide susceptibility of mainly Kelemen Valley and adjacent valleys in Western Black Sea Region Turkey by investigating parameters causing occurrences region a GIS environment applying frequency rate method landslide-prone areas. Many buildings houses area, 382 to be exact, had evacuated General Directorate Disaster Affairs based findings from studies conducted since 1950 were declared “unsuitable for construction residence due disaster.” Therefore, it is vital significance disclose factors consequently prepare maps. For this purpose, 82 exposed areas are determined field surveys checked against satellite imagery. All landslides found have occurred Cretaceous Ulus Formation with same climate vegetation, which not considered distinctive region. These given rise exclude these analyses basis that they proclaimed as common parameters; instead, such slope, aspect distance river taken into consideration assessed ArcGIS™ software. Finally, has been obtained. Furthermore, comparison between existing outcome map, deduced map produced correlation ratio 86 % high-risk finding clearly dictates need accounted when planning new settlement
