A GIS-based extended fuzzy multi-criteria evaluation for landslide susceptibility mapping
Landslide susceptibility mapping (LSM) is making increasing use of GIS-based spatial analysis in combination with multi-criteria evaluation (MCE) methods. We have developed a new multi-criteria decision analysis (MCDA) method for LSM and applied it to the Izeh River basin in south-western Iran. Our method is based on fuzzy membership functions (FMFs) derived from GIS analysis. It makes use of n...
متن کاملlandslide susceptibility mapping for the urmia lake basin, iran: a multi- criteria evaluation approach using gis
although typically small in terms of their spatial footprint, landslide hazards are relativelyfrequent in northern iran. we assess landslide susceptibility for the nearly 20.000 km2 large study area of the urmia lake basin which is dominated by agricultural land use but includes the major settlements areas of the east azerbaijan province, iran. landslide factors are established in form of gis d...

متن کاملA GIS Based Landslide Susceptibility Mapping Using Multi-Criteria Decision Analysis Model at a Regional Scale
The paper aims to produce a landslide susceptibility map by means of multi-criteria decision analysis based on GIS for Qianyang County, Shaanxi Province, China. At first, a detailed landslide inventory map was prepared and fourteen landside conditioning factors were considered: slope aspect, slope angle, altitude, plan curvature, profile curvature, geomorphology, rainfall, STI, TWI, SPI, distan...
متن کاملGIS-based landslide susceptibility mapping with probabilistic likelihood ratio and spatial multi-criteria evaluation models (north of Tehran, Iran)
The aim of this study is to produce landslide susceptibility mapping by probabilistic likelihood ratio (PLR) and spatial multi-criteria evaluation (SMCE) models based on geographic information system (GIS) in the north of Tehran metropolitan, Iran. The landslide locations in the study area were identified by interpretation of aerial photographs, satellite images, and field surveys. In order to ...
