Abstract

Landslide are the common disastrous events in the Nilgiris District, it shows a historical record in the study area. The objective of this present study is to prepare a landslide hazard zonation map. The present study has been carried out by using secondary sources of data. Total 33 landslides have been recognized through Landsat-8 satellite imagery. In this study five parameters have been taken such as land-use/ land cover, rainfall, slope, aspect and geology. The hazard zonation map has been done with the technique of Weighted Overlay Analysis by using GIS software ARC GIS 10.4. The results of this study reveal that the most of the landslide has been occurred in the north and center part of Nilgiris district which are highly prone to landslides. These regions are in very high and high zones.  The northern most part of the Nilgiris is in the very low zone due to densely forest covered. Therefore, the results of this study also reveals that the final map of hazard zonation can be useful for mitigate the hazard and is very helpful to planners and engineers for determining the safe and suitable locations to continue the developmental works.
