Toe erosion induced landslides from şebinkarahisar (Giresun-Turkey): Part I
This case study presented herein describes and analyses the results of the detailed surveys of landslides caused by toe erosion in Avutmus district of Sebinkarahisar (Giresun-Turkey), based on field and laboratory measurements, monitoring and remote sensing data of the study area. Sebinkarahisar has been recognized as a landslide-prone area. Landslides in this area caused several hazards in the houses and farming areas. In view of landslide re-occurrence potential in this area and its close environ, understanding of the failure mechanism is highly crucial. Field investigations, analysis of geological data, and laboratory tests suggest that two important factors have acted together on the slopes to cause sliding. The surficial water and groundwater circulation also played an important role in the initiating the movements. However, instability condition of the slopes is especially connected to the toe erosion created by river.
