ABSTRACT
The importance of geological and geotechnical investigations of landslides occurred at dam reservoirs: Case studies from the Havuzlu and Demirkent Landslides. Landslides, occurring in dam reservoirs, result in a large number of causalities and huge economic losses all over the world. The landslide characteristics were also evaluated by measurements and observations. Laboratory experiments were conducted on the samples taken from the study area, and a landslide database was obtained. To assess landslide susceptibility, hazard and risk in the studied area, firstly, landslide locations were determined through field studies and aerial photo interpretations. With regard to the field investigations, laboratory studies and evaluations of existing and new data, susceptibility map of the area indicated that 88.9% of existing landslides, including Havuzlu and Demirkent landslides, have high and very high susceptibilities and that a risk of new landslides should be expected in the investigated area.
