subalpine ecosystems are highly fragile as compared to biological andenvironmental factors. landslide is one of the ruinous upshots of this ecosystem. one of theimpressionable areas in the cause of natural factor is masoleh watershed in western alborzmt, (iran). in order to landslide hazard zonation, landslide index and frequency ratio methodbased on twelve causative factors such as slope, slop...

Extended abstract In the management of landslide problem, the estimated hazard is an important factor for the creation of thematic maps of the general conditions of risk and constitutes an essential element of decision support for both a proper planning of the territory and for the optimization of prevention actions. With regard to this, GIS can be considered an excellent tool, because it allow...

it is very important to recognize the areas with high potential risk of landslide in order to resist that. in a case study, thirty three landslides have been observed in safarood watershed. the purpose of this study is to recognize factors and zonation of potential areas for landslide. this paper covers specific factors including lithology, fault, height, slope, direction, rainfall, soil, veget...

This study focuses on landslide susceptibility mapping in the Daunia area (Apulian Apennines, Italy) and achieves this by using a multivariate statistical method and data processing in a Geographical Information System (GIS). The Logistic Regression (hereafter LR) method was chosen to produce a susceptibility map over an area of 130 000 ha where small settlements are historically threatened by ...

The large rainstorm happened on Sep. 3, 2004 at Tiantai village of Xuanhan County, Sichuan province, which lead to a oversize landslide. The foreside of landslide slid into the Qian river and formed a dam about 20m height, jammed the Qian river and caused heavy damage and loss. Based on the digital landslide and 3D Visualization Technique, the research of the landslide was started by using the ...
