LANDSLIDE HAZARD ZONATION AROUND ROHTANG (KULLU DISTRICT) HIMACHAL PRADESH

Objectives:

1) To develop a methodology for landslide susceptibility zoning considering landslide source.2) To investigate and assess the potential risk of landslides.3) To generate various thematic maps such as soil, slope, aspect, contour, LU/LC, DEM and other maps.4) Generate a landslide susceptibility map using thematic maps.

Need for the Study:

• The NH 21 runs through the study area. It is the only highway connecting Kullu valley with rest of the country.• This highway has got its additional importance as the supply of defence equipments and essential commodities for defence personnel deployed at Leh has been diverted through this route.• Also trucks to transport apples from valley to the capital and other metropolitan cities of the country starts plying on this highway right from beginning of July. As such it is immense importance to study landslides prone areas along this highway.

Methodology:

• To do the literature survey.• To collect data such as satellite images, topographical maps etc.• To perform analysis on Arc GIS.

TOPOSHEETS REQUIRED- 52H/3, 52H/4, 52H/7 & 52H/8

Data Collection:

Prepared by: National Remote Sensing Agency, Dept. of Space, Govt. of India, Balanagar, Hyderabad.Participating Organizations: I&PH Dept., Govt. of Himachal Pradesh. National Remote Sensing Application Centre, Shimla.Data Used: IRS-1D LISS-3.

Brief Description:

• This project is related to generate landslide susceptibility map of study

area vulnerable to landslides.

• In this respect we have collected data like satellite images, scanned

topographic sheets.

After that we have processed the data using Arc GIS software and produce

output such as slope, aspect, soil, DEM maps. Based on this information we

will produce final landslide susceptibility map of the study area.
