Profile of Scientist and Scientific Staff

Image of Geosciences Department

Geosciences Department (GSD) is one of the oldest departments of IIRS established in 1966 in collaboration with The ITC, the Netherlands, to provide professional training to scientists and technical staff of government and public sector organizations dealing with geoscientific applications such as geological survey and mapping, groundwater resource assessment, mineral targeting and hydrocarbon exploration, and engineering geological mapping. Presently, the department has been evolved into a full-fledged entity for conducting training, education and R&D activities and national level projects on geological resource appraisal and hazards assessment. Significant contributions of the department are as follows:

  • Produced landmark geological maps: (a) geological map of Garhwal Himalaya (1970s), (b) geological map of Cuddapah Basin (1970s-1980s), (c) hydromorphogeolocal maps of different parts of the country including Cuddapah, Vindhyan, Doon valley and surroundings (1970s-1980s), (d) groundwater prospect and quality map of NCR Delhi (2000s);
  • Provided geological input in many national and international projects: (a) Highway Alignment Project in Nepal (1980s), (b) Parbati Hydroelectric Project (1980s-1990s);
  • Prepared Landslide Hazard Zonation and Seismic Microzonation maps: (a) along the pilgrimage route corridors in U.K. and H.P. states in Northern India (1990s-2000s), (b) national highway along Shillong-Silchar-Aizawl route corridor in NE India (2000s), (c) seismic micro-zonation of Doon valley in collaboration with ITC, the Netherlands and Wadia Institute of Himalayan Geology, Dehradun (2000s);
  • Produced numerically simulated physically based models (debris flow) along with rainfall thresholds to help mitigation, slope vulnerability, susceptibility, risk due to landslide hazard in the Garhwal Himalaya (2013-til date)
  • Provided advisory support in National Geomorphological and Lineament Mapping Project of ISRO in collaboration with Geological Survey of India, in numerous developmental and geohazard projects of Uttarkahand state and Public Sector enterprises (2010s)
  • Development of complete spectral library (0.4-16µm) of Proterozoic rocks/ minerals of Aravalli-Delhi Fold belt in Eastern Rajasthan
  • Provided satellite derived data products for mineral abundance/ target maps (space-borne and airborne) and understanding metallogeneis in parts of Rajasthan and Odisha, in collaboration with Geological Survey of India.

The state of the art facility in the department includes ‘hypespectral lab’, ‘engineering geological lab’ and ‘geophysical lab’ hosting VNIR-SWIR spectroradiometers, FTIR spectrometer for infra-red region (2-16 mm), multi-frequency bi-static ground penetrating radar (GPR), vertical electrical sounding, IP resistivity meter, permanent GNSS stations (CORS), dual frequency geodetic GNSS systems, seismic stations with broad band seismometer (BBS) and strong motion accelerograph (SMA), 48 channel engineering seismograph, and direct shear and tri-axial shear strength apparatus for measuring geotechnical properties of rocks and soils.

The present R&D thrust areas of the department includes:

  • Mapping, monitoring and modelling of landslide, engineering geological study for slope stability analysis and infrastructure development
  • Co-seismic and inter-seismic deformations, geodynamics of Himalaya and earthquake precursor study
  • Microwave remote sensing and SAR interferometry for monitoring of land surface deformation due to earthquake, mining and groundwater depletion
  • Hyperspectral image analysis for mineral abundance mapping and targeting
  • Glacier morphology, spatio-temporal dynamics and climate change study
  • Planetary geology of Moon and Mars including characterization of planetary surface and processes
  • Space gravity data (GRACE FO) analysis for ground water depletion study over Indian regions
  • Thermal remote sensing for thermal anomaly detection and monitoring of geological phenomena

In many of the R&D projects, the department has been collaborating with the premiers academic and R&D organizations and stakeholders in the country: (1) Wadia Institute of Himalayan Geology, (2) Geological Survey of India, (3) Central Ground Water Board, (4) Survey of India, (5) IIT (ISM) Dhanbad, (6) Central Institute of Mining and Fuel Research, CSIR, (7) Coal India Ltd., (8) Aryabhatta Research Institute of Observational Sciences, Nainital.
