Evaluation of the Landslide Hazard and Risk Assessment Using GIS and Remote Sensing –Dambovita County

We focused our research on a north part of the central region of Dambovita County, part of the relief unit known as Subcarpathians of Ialomiţa as severe events of the mass movement were reported during time, but have never been the subject of a detailed investigation with modern techniques.

According to the GIS-based risk analysis, the areas that are most prone to landslides are found in the eastern and south-eastern parts of the study area, in the Mercani and Baloiu Hills, where steep slopes are predominant and geology includes schist, flysch, and sandstones.

However, the landslide susceptibility model is theoretical, being an approximate prediction of the real dynamic of the actual situation in the study area, given in terms of probability. On the other side, InSAR techniques depict the real past and present dynamics of the surface, by measuring surface displacement. These two techniques can be cross-correlated in a future study for validating the results of the susceptibility model.
