Abstract
The implementation of GIS spatial analysis was aimed in order to determine the landslidesusceptibility in The Codrului Hills. The methodology for assess landslide susceptibility is based on thepremise that the processes will occur under the same geological, geomorphologic and climatic conditionsas in the past. The analysis of the landslide susceptibility data showed that the most susceptible areas arethe ones with 6-17° slope angles, facing on southwest, with a high drainage density of 4-6 km/km²,overlapping Pannonian deposits, covered by pasture and an amount of precipitation in the cold season between 225 and 250 mm. Finally, the landslide susceptibility map was tested using current landslidedistribution. The test results showed satisfactory agreement between the landslide susceptibility index andthe landslide inventory data. Thus, 92.41% of the current landslides fit the areas characterized bymoderate and high susceptibility and only 0.14% of the contemporary landslides are located in the verylow susceptibility area. The GIS analysis of the landslide susceptibility revealed that most of the studyregion is stable from this point of view (68.65%), mainly due to the prevalence of the low slope anglesand good vegetation coverage.
