Background and objectives: Tehran and Alborz provinces are important zones from an economic, social and political activities point of views in the country; most of the habitations in these provinces were built in areas which are in the risk of landslide. This research, studied the damages and physical-infrastructural vulnerabilities in these areas, considering the landslide hazardous zones base...

A landslide susceptibility assessment for the Three Gorges (TG) region (China) was performed in a Geographical Information System (GIS) environment and Persistent Scatterer (PS) InSAR derived displacements were used for validation purposes. Badong County of TG was chosen as case study field. Landslide parameters were derived from two datasets. The Advanced Spaceborne Thermal Emission and Reflec...

This study used GIS as a tool to map storm-induced landslides from SPOT5 images. Digital elevation model (DEM) of 10m x 10m resolution was used to extract geomorphic landslide causative factors: slope gradient, slope roughness, tangential curvature, relative slope height, total slope height and wetness index etc. Digital geological map was used to extract geologic causative factors: lithology a...

Landslides are one kind of slopes processes have been take place in some area at worldwide and Iran every year, and they are associated with damaged, many people are harmed and losses their properties. The aim of this research landslide hazard assessment in central zab basin in the southwest mountainsides of West-Azerbaijan province, Iran by using information layers and effective factors in lan...

Assessing Landslide Susceptibility Mapping (LSM) contributes to reducing the risk of living with landslides. Handling the vagueness associated with LSM is a challenging task. Here we show the application of hybrid GIS-based LSM. The hybrid approach embraces fuzzy membership functions (FMFs) in combination with Shannon entropy, a well-known information theory-based method. Nine landslide-related...

With so many techniques now available for landslide susceptibility modelling, it can be challenging to decide on which technique to apply. Generally speaking, the criteria for model selection should be tied closely to end users’ purpose, which could be spatial prediction, spatial analysis or both. In our research, we focus on comparing the spatial predictive abilities of landslide susceptibilit...
